Show HN: CoreDNS-GSLB – DNS-based load balancing with GeoIP and Lua healthchecks
by dmachard | 2025-07-18 15:02:41+00:00
Most GSLB solutions are proprietary or Kubernetes-centric. This plugin adds global load balancing directly to CoreDNS for any infrastructure.

Key features: - GeoIP routing (MaxMind + custom YAML mapping) - route users to nearest datacenter - Lua-scriptable health checks - call HTTP APIs, parse JSON, check Prometheus metrics, even SSH exec - Adaptive health checking - automatically reduces check frequency for idle records - EDNS Client Subnet support - get real client IPs through DNS forwarders - Live config reload - no CoreDNS restart needed - TXT record debugging - dig TXT yourapp.com shows all backend states instantly

GitHub: https://github.com/dmachard/coredns-gslb Looking for feedback on the GeoIP implementation and Lua scripting approach!

> Other countries with government-controlled healthcare introduced wait times…

No, they have wait times. Just like the US does.

https://www.statista.com/chart/33079/average-waiting-times-f...

"According to a recent study by the Consumer Choice Center, the average wait for a GP appointment in the United States in 2023 was around three weeks, two to ten times longer than in Europe. For example, in that year, the average waiting time for a medical consultation was two days in Switzerland, six days in France and ten days in the United Kingdom and Italy."

Seems reasonable.

For most people, it'll be returned as they leave.

For people who really shouldn't be there, it serves as a filter; If they can't afford to loan the US $250, it is unlikely they will be able to afford theirlife necessities once in the US. Such a person should solve their issues BEFORE traveling to the US.

For visa overstayers, it funds their deportation.

Bad guess, I am not sure what OP really intends (perhaps you don’t consume whilst you sleep?!) because as you probably are starting to remember from primary school your body maintains homeostasis by continually respiring. It doesn’t suddenly decide to take a dump.

Ok, it does, but even when it does that, in order to do that it has been continually maintaining homeostasis

While I broadly agree with you, and am a self-taught (and occasionally mentored) software engineer, I have often thought that to “care about retaining employment and lowering anxiety” is by far the more rational approach in the corporate-dominated software world of today.

Over a long enough career I think we all see that a high percentage of interchangeable cogs at the BigCos end up with a lot of wealth and very little job-induced stress. Whereas among those who chafe at cogdom and “care about the code,” a tiny fraction make it big while most carry more stress than they should, shoulder more day-to-day responsibility for making things work, and do it for less reward.

I don’t regret being wired for creativity, but the boring people are doing great in this business. Maybe AI changes all that soon, but I wouldn’t dare to bet on which direction it splits.

> take a photo and identify you

Actually neither happened. The article says they were not able to find any identifiable information online. They had to use drivers license instead.

> the fire marshal sent links to Clearview AI face search results, an archive of school play photos and another to an archive of high school formal photos. He said he couldn’t find associated social media but offered to get a driver’s license photo for the detective. “We have access to that,” he wrote.

I read the sequence as,

1. They started with a protest video

2. Clearview provided public images of the same person, but no name. It was certainly more identifiable (e.g., their high school).

3. Then somehow they get the driver's license photo. Do they use the original protest video, or the Clearview images? How does this search even work? Nobody knows. Lazy journalism.

As readers, we have no idea if the Clearview search was actually important, or a dead end.

Ask HN: Knowledge/skills to develop and contribute to projects like Unsloth?
by hedgehog0 | 2025-07-18 15:05:27+00:00
Hi everyone,

I am a Master student in math in Germany and will graduate recently, since I am also interested in programming and LLM, I have been following HN and subs like r/machinelearning and r/localllama for some time. I have been really impressed by projects such as Unsloth that could help people train and/or fine-tune on commercial-grade GPUs.

I also want to develop/contribute to projects such as Unsloth, however, I'm not sure what are the background knowledge or skill sets one should have to contribute. So I was wondering if you have any recommendations of resources and materials for learning more about (post-)training, fine-tuning, and general ML/LLM Ops?

Thank you a lot!

P.S.: I'm reading and working through the book "Hands-on Large Language Model", and I have a Macbook Pro but no NVDA GPUs.

Hi Peter, My H-1B status is set to expire in November of this year, marking the end of my 6-year limit. My NIW (EB-2) petition is currently under review. In the event that my NIW is approved after my H-1B has expired, would my employer still be able to file for an H-1B extension on my behalf?

U.S. work authorization isn't required to work for a U.S. company if the worker will be working remotely outside the U.S. Regarding her work visa options, they are limited. The only option immediately available is the O-1 visa, which is for people of "extraordinary ability," a high standard but attainable by many talented professionals. The H-1B "professional worker" visa is much easier to qualify for but it's only available once a year and via a lottery so it's not a realistic option. If she really wants to work for a U.S. company remotely or in the U.S., then she should have a consultation with an immigration attorney and have her background evaluated.

We had a good run, now it is time to scratch this evolutionary iteration as well and start from a clean slate again. There were mass extinction events before also and life restarted in a new form. It is time now for the same to happen, we are not capable of learning and behaving. While we might have advanced further than any species on Earth before, we are an evolutionary failure nevertheless. And what do you do with bad code? You rewrite it.

Kendo and Fencing are both sports. For starters a shinai is way lighter than a real sword, even an iaito is usually lighter than a real sword. The "meta" then evolves around a might faster and lighter style.

Slicing with a katana is also very technical, if you've ever watched tameshigiri being able to properly cut is much more than just scoring a point. Kendo tries to simulate that in its subjective judging parameters, but having your attacks properly cut will be a different technique than sport Kendo.

In real life warfare knowing how to not get your weapon jammed in an opponent is important for survival but is very hard to practice in modern day life...

Edit: as an analogue: if you learn boxing or muay thai, first you learn how to hit a bag properly. Then you spend 10-100x longer figuring out how to execute those techniques in an actual fight. Then you watch a master like Canelo or Tawanchai work their beautiful art and feel depressed

> Things like what happens when someone who looks 25 is actually 55? Who should they socially acceptably date?

I don't know man. There are already plenty of 55 year olds dating 25 year olds right now regardless of looks. Also, not as extreme, but looking like you're in your 30s throughout most of your later adult life is not that uncommon nor difficult. Barring any health issues, that's where most people's looks stabilize.

Why isn’t it possible — or is it — to make libc just use uring instead of syscall?

Yes I know uring is an async interface, but it’s trivial to implement sync behavior on top of a single chain of async send-wait pairs, like doing a simple single threaded “conversational” implementation of a network protocol.

It wouldn’t make a difference in most individual cases but overall I wonder how big a global speed boost you’d get by removing a ton of syscalls?

Or am I failing to understand something about the performance nuances here?

My brother works with COBOL for a bank here in Brazil, he is young (in his 20s), started before finishing his degree. Pay is poor, hours are insane, he is overworked as hell, and anything “modern”, like git, is out of the question.

He’s trying to learn Go now and modernize himself to see if he can get out. I’m trying to help as much as I can. Hopefully, he’ll land a job somewhere else this year.

Meanwhile, in Australia, they’re raising student visa fees to $1279 (USD.)

US student visas, after all fees are roughly $500 (USD.)

UK skilled worker visas are about $1660. The H1B is about $1700.

The U.K. multi entry visitor visa for 10 year validity is about $1200.

The U.S. version: $185

I understand it’s popular to post articles that sensationalize how “bad” the U.S. is, but reasonable people probably should have some perspective.

Hi HN,

I've been using ChromaDB recently for my vibe projects, but missed a simple web GUI that runs on any LAMP stack. So I ~built~ vibe coded phpMyChroma

• Browse tenants, databases, collections, docs • Semantic search • Add/Edit/delete in place • Zero dependencies beyond PHP 8.3 with curl • MIT license

I’d love feedback on: - feature gaps that stop you from using it - security pitfalls I might have missed - something not working properly

Thanks!

One has to love how it's two weeks after the big ugly spendthrift bill was passed, and its actual contents are still being dissected. Not just small details, but entire topics.

Where's the time for us citizens to be informed? And the time to write our senators and representatives so they know what their constituents think? Of course that's idyllic, and we haven't had that in decades. At least things like the (anti-) "PATRIOT" act were bipartisan, despite selling out the people. But the sheer speed this barge of incoherent trash was wholesale rammed through really shows how utterly feckless Congress as a whole has become.

It seems like they need to watch more of those 90's "Just say no" ads.

> after realizing that the risks are low, but life changing if it happens.

I think these risks are more common than was previously discussed on the internet. For a long time reports of very negative experiences were dismissed, laughed at, downplayed, waved away as symptoms of something else, or excused as something positive but mysterious.

It’s becoming more acceptable for people to discuss their negative experiences and not get downvoted or attacked for sharing them.

With a dedicated Gemini client I simply have to trust/verify code provided the client developer.

With your solution now I have to trust/verify code provided by the browser developer(s), the apparatus the browser provides for extensions, and code provided by the extension developers.

If I'm super paranoid I can just look at a .gmi in Notepad or vi and understand it. I can't do that with all but the most basic HTML.

> Acting like this is UBI's fault is kind of weird.

As Noah Smith wrote:

>...Now, increased leisure time isn’t zero benefit — obviously it’s nice to be able to sit around and do nothing and live off of government cash for a little while. But it represents a steep tradeoff — programs like this are already very expensive in fiscal terms, and if they make people work less, that only adds to the total economic cost. If leisure time is all we’re getting for all of that money and lost output, it’s highly questionable whether the intervention is worth it.

A guy called Steve Paul coached me for a few years, the connection is that he was Peirce Brosnans double in Die another Day. He got motor neuron disease just before covid and the poor old sod fell down some stairs when he was on holiday and died.

Irony can sometimes be a bit harsh.

Fencing was such a big part of my life for so long, but when I got to my late 30's the power went out of my body. It was shocking, but just true, I couldn't do what I used to be able to do when I was young and I had to come to terms with it. A lot of people go into coaching, or make their peace and fence as a veteran, but I couldn't do that. It took me a long time to grasp why because I used to coach when I was competitive, so why could I not abide it when I knew I could not compete.

The answer was not attractive. I envy the young. I cannot stand to watch them and know I am not one of them.

If you are young then take up swords, or racquets, or gloves and revel in your sinuous power. Soon it will be gone, and all you will have is memory, until something comes sliding and slipping and takes even that, and you find yourself tumbling into the night.

This seems to be a mixed bag for privacy.

You have the judge coming down on the side of privacy, which is good; but the circumstances of the particular case are troubling (allegations of someone throwing a rock at someone else).

I'd be happier gaining ground for privacy rights with cases about, e.g., blanket surveillance, using surveillance for political purposes, surveillance capitalism, etc. Then we figure out where the best lines are for when surveillance actually should or can be used.

(Edit: And ill-considered downvotes is why I'm not going to bother to try to have a meaningful discussion on HN.)

Its not JUST cost.

Insurance company covers person.

Person gets chronic ill, with covered disease.

Person is now 'less profit' or a cost.

Company, against contract, refuses to cover medication/procedures.

Company waits out patient to die.

The person is demonstrably wronged, but these companies can just wait sick people out. And that's precisely what happened with UHC. You know, Delay Deny Defend.

Netflix is building a large part of their production style around people keeping netflix running in the background 24/7. Writers are told to have the characters frequently "exposition dump" because the viewers aren't actually watching. Generative AI makes total sense if you have a product that no one is actually watching; just using employing it the same way I employ a white noise machine to help my toddler sleep.

If the basic capabilities are present the thing that matters is motivation.

Self-taught naturally correlates with motivation (as well as a few other mixed traits).

It's neither a cause or guarantee of performance, but it can be very useful information to know about candidates when recruiting.

Indeed.

The 2nd amendment and the notion that we have physical power over the government is going to be whittled away as facial recognition and omnipresent government spying via data brokers gives them all the info they need to spy on every citizen, all the time.

AI means they don't only collect all the data they want for when they need it ala NSA 2008, but they can have a robot army of analysts transcribe photos and phone calls instantly and analyze for sentiment, flag for review.

If we don't demand, as a society, that government stay out of the business of the people, and that the military stay out of the business of civil society (ICE/National Guard/Marines), we are in for true evil.

> prove flight was safe

Flight did not have potentially uncontrollable consequences.

> human cloning

No uncontrollable consequences.

> Nuclear fission

To a reasonable standard, yes! I remind you that there was a concern of atmospheric ignition that was reasonably disproven before the first test.

> CRISPR technology

Tbh they should have, and I fully advocate this standard for any sort of live genomic research as well.

Also, just fwiw. I am not scared of AI. I'm not even particularly scared of dying in a global armageddon (as the song says, "we will all go together when we go", and tbh that's genuinely a relief). I just think, fairly dispassionately, that it's going to happen. You can't explain your disagreements with "my opponents are just emotionally affected."

> Your argument must be: we have to do things differently this time with AI because the stakes are higher.

I don't understand what you're saying here. That is in fact my argument. My whole entire point is just that it's not something beyond our means by any means- we have to do it, and we're capable of doing it, so we should do it.

My trial co-founder and I built Unpitched as a 5-week run to test if we'd work well together. The twist: we're experienced software engineers yet AI wrote ~90% of the 24k lines of code in Unpitched.

The product analyzes customer interview transcripts to catch when founders slip into "pitch mode" instead of learning. It's based on principles from The Mom Test book - essentially a digital coach that flags your mistakes and gives you personalized advice how to do better.

Why this project for our trial:

- Real problem we'd witnessed (founders talking too much in user interviews) - Tight scope but production-grade requirement - Chance to push AI-accelerated development to its limits

Tech: Next.js 15, Supabase, Trigger.dev, GPT-4.1 via Vercel AI SDK. We used Cursor, Claude Code, V0, and (briefly) Grok for development.

Key learning: AI development requires adopting new working patterns. You can think of AI as a chaotic software engineering intern. You need to be highly intentional in guiding the AI to do the right thing. Just like with human teams, bad managers get bad output from their people and the same applies to managing AI.

If you're an experienced software engineer, you have a lot of implicit assumptions about how to build software, how to rate importance of tasks, etc. You need to transfer these to the AI, and we think we found early patterns how to do this well.

For example, we used "walking skeleton" and "tracer bullet" concepts to structure project planning we did with AI. We found the basic pattern of think-research-brainstorm, and plan before writing any code to dramatically improve the quality of AI coding, as the project gets more complex. E.g. we'd plan error handling with AI first, save it as a doc, then use that as context for implementation - this kept the AI consistent across the codebase.

We shared details of this approach at Warsaw AI Tinkerers (over 200 people attending) a couple of weeks ago.

The co-founder trial worked - we built a working mini-product in 5 weeks, found out how we approach this alien technology in the form of modern AI, and uncovered many interesting personal quirks of each other (everyone has them).

You can check out Unpitched at https://unpitched.app. Sadly, we require sign up as underlying LLM calls are a little expensive.

We wrote more about how we approached the cofounder trial process at https://unpitched.app/about. Let us know if you have any questions about our trial, maybe share your own stories of looking for cofounders, or have any feedback on the app!

PS. Shootout to Circleback team (YC W24) as the only note-taking app we found that has working webhooks that we could integrate with Unpitched.

The risk is that it’s a false idea triggered by the psychedelic.

Maybe a better example would be my friend who took psychedelics and then believed he was in communication with Elon Musk. This one is more obviously a false idea, but nevertheless he was convinced it was real for a period after the psychedelic experience.

There’s a mystical concept that psychedelics open your third eye to see the world as it really is or something, but psychedelics are notorious for giving false ideas and making them seem like revelations. It’s obvious when it’s nonsense (like telepathy with Elon Musk) but it’s less obvious when the implanted idea is something like “your husband secretly doesn’t love you”. Another strangely common report is the belief that people around you have been replaced by clones, which can get scary very fast if the person can’t separate the idea from reality.

The operations used to perform these computations are utilizing algorithms backed by lattice-problems that are NP-hard to break.

edit: The only leaking information in this case are what operations you'd like to perform on the encrypted data. e.g., you now know that you've incremented the password by x amount, but you don't know what the plaintext was before, the plaintext after, _or_ infer what the value is by knowing you've modified the encrypted data by x amount.

edit2: Now I think I understand the question. The encryption is technically weakened because you can know what operations are made on the underlying data. Though it's still an advancing field, and there are promising developments with what's called circuit privacy[0] to prevent the server knowing the operations made as well.

Sorry, my phrasing was not clear. Your metabolic rate is generally lower during sleep than during the day; you definitely lose more weight overall during the day than while asleep. But, while you're sleeping, you don't eat anything. And quality sleep is necessary to maintain overall metabolic function. I'm not a scientist and didn't mean to make any strong claims!

Two short articles I was basing this off of:

- "When somebody loses weight, where does the fat go?" https://www.bmj.com/content/349/bmj.g7257

- "Sleep and Metabolism: An Overview" https://pmc.ncbi.nlm.nih.gov/articles/PMC2929498/
