You clearly have not taught mathematics at either the college level or the high school level. But your experience carries a great deal of weight. You are correct. I’ve taught mathematics at Purdue University, Florida State University, University of Kansas, various community colleges and in a prison. I don’t know what I’m talking about. The book in question should be a course at every high school. Each high school will certainly have enough students who can take such a course to justify having the course.

By the way, don’t look up what an outlier is and don’t forget that your anecdote is, in fact, data.

Yep.

Either you radically gatekeep your community to ensure it only allows people discussing topics you find interesting and watch it die as newbies get turned away while stalwarts leave for whatever reason, or you welcome "new blood" with their own interests which are not always completely aligned with your own and watch the community change around you.

And it's not just forums, it happened in usenet, it happens in social circles and friendship groups, it happens in suburbs or neighbourhoods. I'm pretty sure it happened around campfires and caves 50 thousand years ago.

DIGIPIN is an open-source, geo-coded addressing system developed by India Post in collaboration with IIT Hyderabad and NRSC, ISRO. It enables “Address as a Service” (AaaS) by linking physical locations to its digital representation, allowing seemless encoding/decoding.

This is region specific (India only).

Yeah, I hear you. Many things are simplified in this crypto code, for example there’s no dynamic allocation. At the same time it’s incredibly difficult to get a realistic model of the hardware instructions because they all have side effects. And it gets incredibly more difficult if you try to prove real world, hand optimized code (vs academic proof of concept code).

With all this said, I think this could be a good inspiration and look forward to seeing advancements!

As evidenced by the other replies by OP, it’s a hyperbolic and bad take. There’s plenty of companies doing just fine with Rails codebases. Many of which are a decade or more old now and have done just fine with the inter generational transfer that happens due to natural employee attrition and haven’t been held hostage by one or two all-knowing engineers.
by throwanem | 2025-06-12 03:29:25+00:00
I said "empire builders," not "engineers." Nor did I say "held hostage."

My perspective on this is that of a working engineer who made a deliberate choice, now nearly 15 years ago, to avoid ending up stuck in the same decreasing-radius career spiral I saw Rails leading me toward - so I went and did some other things, then spent a decade building modern TypeScript instead, mostly on Kubernetes, without losing the ability to knock out a quick one-off script or architect a system top to bottom as I need. It's worked out splendidly for me! I suppose I might have done as well if I decided differently, but I admit I don't see how.

The later non-Commodore A4000Ts in TFA, however, are much better systems IMHO than the original Commodore-badged one and far easier to get. I've got one here too, with a QuikPak '060, Picasso IV RTG and Ethernet, and it runs very well in AmigaOS 3.9.

It cuts the other way as well. It's incredibly easy to file suit against larger corporations (e.g. your landlord in small claims) and just represent yourself and be confident all you're potentially out is the court filing fee. I've personally done it twice and settled before it went to trial; without the American rule there would be no way I could risk having them take it to trial and pay their fees.

Hey HN, I just launched 10AppDeals – a minimalist app deal site that features just 10 high-quality app offers each day (iOS, Android, and cross-platform). As an indie dev myself, I often felt that smaller apps get lost in massive deal listings. So I built something simpler.

It’s also a small win for SEO — devs get a backlink when their app gets archived in the “Wall of Apps.”

This is my first solo product launch and I’m currently offering free launch slots for devs to promote their apps as a thank-you for early support. Use code FREELAUNCH if you’re interested.

I’d really appreciate your feedback on the UX, concept, or anything you’d improve. Thanks for checking it out!

In general this is of course an active area of research, but yes, you can do something that and people have done it successfully[1] by adding extra layers to an existing model and then continuing to train it.

You have to be careful about the "same data" part though; ideally you want to train once on unique data[2] as excessive duplication can harm the performance of the model[3], although if you have limited data a couple of training epochs might be safe and actually improve the performance of the model[4].

Kind of the opposite, I think AWS was the first hyper scaler so tooling did not exist for many of these problems back then

Like they have their own custom clustering software where you would probably use k8s if you were to rebuild things today

Repeat this over a million different tools, etc

RI/FI is similar to having long-lived branches in Git. Imagine you have a "develop-word" branch in git. The admins for that branch would merge all of the changes of their code to "main" and from "main" to their long lived branches. It was a little bit different than long-lived git branches as they also had a file filter (my private branch only had onenote code and it was the "onenote" branch)
Show HN: I built a tool to show how people trained for your goal marathon time
by tmulc18 | 2025-06-12 03:34:58+00:00
The idea for this came from wanting something like Naviance (let’s you see the GPA and test scores of admitted students for a given college) for marathon running.

In general, we’re working on making your running data more useful, and our newest tool, called, "Marathon Cohorts," gives you stats about runners who finished a marathon in a given time. You pick a marathon time / cohort and then look at

- Weekly training mileage

- Fastest 5k, 10k, half marathon, and 30k during training.

You can adjust the cohorts to see how these values change as the marathon time gets slower / faster.

If you are logged in and connected with Strava / Garmin, we compute your stats for you and overlay them. But you can explore anonymously–no login required.

There’s also a little shareable image generator we’re experimenting with (to make it easier to share on Strava).

It’s free right now, but we’re considering a freemium model — and we’d love thoughts on:

- Giving users X free queries (per month) before locking the tool?

- What would feel worth paying for?

- What other stats do you want to see?

- Better name for the tool?

Let us know what you think!

My country has a fairly high % of PhD holders, but nowhere near enough jobs for them, so they end up getting regular jobs (e.g. I have a friend who got a PhD in laser physics, who now plays with AI models for license plate recognition).

These people usually leave the PhD off their CV, as some employers frown upon it, as they think the person will have higher expectations and be hard to work with.

and sometimes before starting ... at two weeks' out, they'd had to change the salary offer (down) because they had screwed up the salary calculation, expressed surprise I'd said I planned to use the unlimited vacation policy to take a fixed four weeks a year (they felt it was a lot), changed the offer from employee to contractor, referred me to their accountant for what was really the simplest of accounting queries, sent me an equity calculator with an assumption of a $10bn sale price, and some other weird stuff. Really should have known better, and only lasted a few months -- my old company reached out to check I was happy in the new role, and had me back within a fortnight of checking in.

> LoRA does exactly the same thing as normal fine-tuning

You wrote exactly so I'm going to say "no". To clarify what I mean: LoRA seeks to accomplish a similar goal as "vanilla" fine-tuning but with a different method (freezing existing model weights while adding adapter matrices that get added to the original). LoRA isn't exactly the same mathematically either; it is a low-rank approximation (as you know).

> LoRA doesn't add "isolated subnetworks"

If you think charitably, the author is right. LoRA weights are isolated in the sense that they are separate from the base model. See e.g. https://www.vellum.ai/blog/how-we-reduced-cost-of-a-fine-tun... "The end result is we now have a small adapter that can be added to the base model to achieve high performance on the target task. Swapping only the LoRA weights instead of all parameters allows cheaper switching between tasks. Multiple customized models can be created on one GPU and swapped in and out easily."

> you can merge your LoRA adapter into the original weights (by doing "W = W_{0} + ∆W") which most people do

Yes, one can do that. But on what basis do you say that "most people do"? Without having collected a sample of usage myself, I would just say this: there are many good reasons to not merge (e.g. see link above): less storage space if you have multiple adapters, easier to swap. On the other hand, if the extra adapter slows inference unacceptably, then don't.

> This highlights to me that the author doesn't know what they're talking about.

It seems to me you are being some combination of: uncharitable, overlooking another valid way of reading the text, being too quick to judge.
by throwanem | 2025-06-12 03:37:25+00:00
Exactly so.

I'm not actually averse to a programming environment where the only ground truth is the running image. I love that kind of environment! In my editor, where worst case I dump some state when I restart, and I can just not play such dangerous games when on call or there otherwise exists a risk of winning such stupid prizes. Production has rules. Or it had better.

That said, if you want me to go back to dynamic typing, there's a fee. The grass really is a lot greener over here.

> For context, if we tried this with “vanilla Git”, before we started our work, many of the commands would take 30 minutes up to hours and a few would never complete. The fact that most of them are less than 20 seconds is a huge step but it still sucks if you have to wait 10-15 seconds for everything. When we first rolled it out, the results were much better. That’s been one of our key learnings. If you read my post that introduced GVFS, you’ll see I talked about how we did work in Git and GVFS to change many operations from being proportional to the number of files in the repo to instead be proportional to the number of files “read”. It turns out that, over time, engineers crawl across the code base and touch more and more stuff leading to a problem we call “over hydration”. Basically, you end up with a bunch of files that were touched at some point but aren’t really used any longer and certainly never modified. This leads to a gradual degradation in performance. Individuals can “clean up” their enlistment but that’s a hassle and people don’t, so the system gets slower and slower.

Great quote from him here.

How often do you read ChatGPT's entire response?

I rarely.

If you ask a human who understands the value of time, you will answer in fewer words. Unless their job is to illustrate, nobody wants to bore us.

But ChatGPT (or any other chatbot) lacks this ability. They assume you have all the time in the world, and its answers can be as detailed as possible.

However, I found this technique helpful in cutting the fluff and getting to the point quicker.
by firesteelrain | 2025-06-12 03:37:57+00:00
GP has a valid point. We had a Git repo managed in BitBucket that was gigantic because it contained binary files and the team didn’t know about LFS and storing them in an external tool like Artifactory. So checkouts took forever and even with shallow clones it took forever. With a CI/CD system running constantly and tests needing constant full coverage and hundreds of developers well it eats into developers time. We can’t just prune all the branches well because of compliance rules.

So we ended up removing all the binary artifacts before cloning into a new repo then making the old repo as read only.

Microsoft seemed to want to mirror everything rather than keep source depot alive.

We had another case where we had a subversion system that went out of security compliance that we simply ported to our git systems and abandoned it.

So my guess is they wanted everything to look the same and not just importing the code.

I'm going to give you guys the keys to the kingdom. If you do a reddit search for "plex server sale" you will find dudes that share membership to their curated Plex server.

I pay $20 for a server with nothing but 4K remuxes (zero-quality loss from 4k blurays). 5 streams, no transcoding allowed, so you need an nvidia shield because after testing a bunch of devices those are the only ones that play _everything_ without transcoding, even DTS and Dolby Vision.

This reads to me like "I don't have the skill, so I don't understand what quality even means." Which is the main issue with using AI.

Comic art is as abstract, expressive, and integral to the final product as "story, structure, and dialogue." Using the art to express motion, setting, emotion, etc is so key. It's why most comic artists are masters of figure drawing.
Show HN: Rolling Bloom-chain – A lightweight rolling Bloom-based blockchain

Hey HN,

I’ve been building a minimal blockchain-style system called Commitchain, designed for a very specific use case:

Making irreversible, timestamped personal commitments that can be verified probabilistically — with no tokens, no consensus, and no full sync.

I’ve written a whitepaper that explains the architecture, including pseudocode. Core idea came from thinking how light nodes could verify history without needing history.

AI smartypants keep saying that smart people use AI as a tool and people who are... not smart... view it as an oracle.

Given this administration's to-date track record with AI it seems that they're using it as an oracle.

I have zero faith that the current administration won't just feed papers into it, ask it "so, like, is this cool or what?", and rubber stamp what it shits out.

It was important to me that it be 100% private and local and wanted it to be a one time payment solution. Because it locally process your data it can be a one time payment text to speech app.

No. From the linked page:

So it kinda came out did it? I remember seeing it in PC Mag, I guess 93 and thinking man Amiga is in a lot of trouble. My best friend at the time wanted one so badly and I thought he was nuts because to me it was clear as day the 4000 was the last Amiga, NT was amazing and from build 189 on, Windows 95 was clearly going to be good, and it was. I think by late 1995 I'd forgotten all about Amiga my friend never got a T because amiga died, and we all switched to windows machines. I still feel like if gnome and kde hadn't been in competition, linux would have stood a chance around that time, especially if Mandrake had gone more mainstream.

A return of the 1980s home computer form factor in modern tech could be awesome:

Imagine a laptop but with a full-sized keyboard. Doesn't need to be razor thin. More like a portable desktop. Make it wedge-shaped like the Amiga A500 or C64 or Atari ST 520. All the ports. Maybe a detachable display that can fold like a regular laptop clamshell, but optional so you could buy one without a display.

Maybe an operating system that lets you code and create as soon as you take it out of the box and plug it in, and it could be perfect for reintroducing the magic of computers to a new generation.

I won't touch level 8/9 nothings, other than to say I don't think they're coherent. But I am of the metaphysical camp that thinks there will be at least some small ground truth which physical law or object which cannot be reduced, an axiom of nature. Physics unfortunately will probably always be limited in distinguishing between basic facts which are truly irreducible, and those which are simply limits of our observational abilities. That's the thing that bothers me; even if there were a single beautiful law of nature that just IS, one which we actually manage to postulate based on evidence, we will never know for sure. GR definitely has a beautiful mystique, it's a shame that it's most likely just a mathematical approximation.

I am starting to feel like hallucination is a fundamentally unsolvable problem with the current architecture, and is going to keep squeezing the benchmarks until something changes.

At this point I don't need smarter general models for my work, I need models that don't hallucinate, that are faster/cheaper, and that have better taste in specific domains. I think that's where we're going to see improvements moving forward.

Worked at AWS in the past. This resonates. Let's of missed chances. For example, the Alexa for Automotive team initially impressed with a well-produced demo video that painted a compelling vision of in-car voice integration. However, that vision unfortunately never translated into real-world execution. Despite having a major opportunity to collaborate with one of Asia’s largest automotive manufacturers—an ideal partner to bring Alexa into the vehicle ecosystem—there was little to no follow-through. The opportunity was essentially ignored.

From my perspective, one of the core issues was cultural. The Alexa teams were often staffed by long-timers with substantial RSU grants, many of whom appeared more focused on preserving internal influence and career security than driving bold external partnerships or innovation. It indeed felt less like a team pushing the envelope, and more like a collection of fiefdoms guarding their territory.

In the end, it was a missed opportunity—not just for Alexa, but for Amazon to play a central role in the connected car revolution.

“I don’t give out that information (as a matter of principle/because my mother told me not to/because people close to me have been victims of identity theft/because I’m old enough to know better).” Or some variation thereof. It’s enough to say that you don’t because you choose not to, but some people will belabor the point until you give an answer that has the ring of finality and can communicate that it isn't a matter of debate, but a matter of conscience, or rationale, or whatever principle(s) guide you.

Or you could provide a joke answer that is absurdly high or low or wrong, like saying that you weren’t born yesterday, or that you were born at night, but not last night, or in the day, but not yesterday. This might work for those who you are closer with personally, but some may find this kind of answer dismissive and will persist or get upset. If in doubt, use the principle-based approach I mentioned above instead or in addition to the joke one, as a way of showing that you’re answering in good faith and take their question seriously as asked.

Honestly I read (or rather, listen to) a lot of books already by getting the epubs onto my phone then using a very basic TTS to read it out.

> Neuroplasticity is the brain’s remarkable ability to adapt its structure and function by rewiring neural connections in response to learning, experience, or injury.

The invention and innovation of language, agriculture, writing, and mathematics has driven the change in neuroplasticity remodeling, but the overall structure of the brain hasn't changed.

Often in modern societal structures there has been pruning of intellectuals, i.e. the intelligent members of a society are removed from the gene pool, sent to Siberia. However, that doesn't stop the progeneration of humans capable of immense intelligence with training and development, it only removes the culture being passed down.

And, I say, with strong emphasis, not only has the brain of humans been similar for 25,000 years, the potential for sharpening our abilities in abstract reasoning, memory, symbolic thought, and executive control is *equal* across all sexes and races in humans today. Defending that statement is a hill I'm willing to die on.

"Mindset" by Carol Dweck is a good read.
