Show HN: TrackerNews – Keyword monitoring and insight extraction
by winchester6788 | 2025-12-03 20:29:44+00:00
I built trackernews because, originally, I wanted to track opinions on few stocks I was interested in across some subreddits.

The core idea is that, by defining keywords, and a description, trackernews identifies actually revelvant posts and extracts user-defined data points from these posts.

Along with defining keywords, trackernews also allows the user to define various types of fields which trackernews extracts from the posts.

This allows the users to get a glancable/ searchable dashboards along with important insights surfaced.

I pre-created some topics which people may find interesting for publis browsing

Opinions on LLMs, agents, agentic tools - https://trackernews.app/browse/Opinions%20on%20LLMs

Discussions about Databases - https://trackernews.app/browse/Database%20Debates

Opinions and releases of Mac, IOS apps - https://trackernews.app/browse/Mac%20and%20IOS%20apps

Would love any feedback on the approach, UX and the idea.

Thanks, Praneeth

> Another choice we made without admitting it: we socialize the costs of aging, but only after families go broke first.

We effectively do the same in New Zealand even though our healthcare system is very similar to the NHS. Once you go into state funded nursing, then you can keep NZ$284,636 of assets (if unmarried) and NZ$56 per week of any income. Median house price is NZ$770,000 so individuals often are forced to sell their home.

So effectively bankrupted although not quite $0.

If, like me, you're not a real mathematician but suffered through linear algebra and differential equations, you can still totally understand this stuff! I started off teaching myself differential geometry but ultimately had far more success with lie theory from a matrix groups perspective. I highly recommend:

and

My friends were all putnam nerds in college and I was not, and I assumed this math was all beyond me, but once you get the linear algebra down it's great!

> AI-powered map

> none of it had anything to do with what I built. She talked about Copilot 365. And Microsoft AI. And every miserable AI tool she's forced to use at work. My product barely featured. Her reaction wasn't about me at all. It was about her entire environment.

She was given two context clues. AI. And maps. Maps work, which means all the information in an "AI-powered map" descriptor rests on the adjective.

Did they? AFAICT what they actually said was not to expect a faster Steam Deck any time soon, which was true, because the OLED version had basically the same performance as the original and in the two years since they still haven't released anything faster.

It kinda seems like you're conflating Microsoft with Seattle in general. From the outside, what you say about Microsoft specifically seems to be 100% true: their leadership has gone fucking nuts and their irrational AI obsession is putting stifling pressure on leaf level employees. They seem convinced that their human workforce is now a temporary inconvenience. But is this representative of Seattle tech as a whole? I'm not sure. True, morale at Amazon is likely also suffering due to recent layoffs that were at least partly blamed on AI.

Anecdotally, I work at a different FAANMG+whatever company in Seattle that I feel has actually done a pretty good job with AI internally: providing tools that we aren't forced to use (i.e. they add selectable functionality without disrupting existing workflows), not tying ratings/comp to AI usage (seriously how fucking stupid are they over in Redmond?), and generally letting adoption proceed organically. The result is that people have room to experiment with it and actually use it where it adds real value, which is a nonzero but frankly much narrower slice than a lot of """technologists""" and """thought leaders""" are telling us.

Maybe since Microsoft and Amazon are the lion's share (are they?) of big tech employment in Seattle, your point stands. But I think you could present it with a bit of a broader view, though of course that would require more research on your part.

Also, I'd be shocked if there wasn't a serious groundswell of anti-AI sentiment in SF and everywhere else with a significant tech industry presence. I suspect you are suffering from a bit of bias due to running in differently-aligned circles in SF vs. Seattle.

The author has unquestioning assumption that the only innovation possible is the one with AI. That is genuinely weird. Even if one believes in AI, innovation in non-AI space should be possible, no?

Second, engineering and innovation are two different categories. Most of engineering is about ... making things work. Fixing bugs, refactoring fragile code, building new features people need or want. Maybe AI products would be hated less if they were just a little less about being able to pretend they are an innovation and just a little more about making things works.

I don't disagree with the sentiment. But let's also be honest. There is a lot of improvement to be made in security software, in terms of ease of use and overcomplicating things.

I worked at Google and then at Meta. Man, the amount of "nonsense" of the ACL system was insane. I write nonsense in quotes because for sure from a security point of view it all made a lot of sense. But there is exactly zero chance that such a system can be used in a less technical company. It took me 4 years to understand how it worked...

So I'll take this as another data point to create a startup that simplifies security... Seems a lot more complicated than AI

In 1995, I received an email from someone named Conway asking me for more details about some silly thing I wrote in sci.math usenet group. Later I came to know more abut him as John Conway. Sadly I lost access to those emails.

Now, I'm unaware of this strange GoL world with amazing work people are doing. Sometimes I wonder which frontiers of progress, should we as human race be utilizing this amazing creative potential of the current generations.

Countries like Singapore already figured out that if you pay public servants very well

Congressmen get paid 170K/year, get pension after only 5 years (MTG is leaving just after she becomes eligible), plus they only work like 6 months in a year, right? Not sure about healthcare and other benefits. While they can't get rich on this salary, this does seem pretty decent salary and perks, right?

How do other democracies solve this problem?

VistA EHR works reasonably well for end users but the problem is that the underlying platform is kind of a dead end. There's no practical technical path to keep it moving forward with major new enhancements (some of which are legally mandated for compliance). Hardly any developers have the platform skills, no one wants to learn (career suicide in most cases), and modern tools don't support it. It's a shame but that's the reality.

> But then I realized this was bigger than one conversation. Every time I shared Wanderfugl with a Seattle engineer, I got the same reflexive, critical, negative response. This wasn't true in Bali, Tokyo, Paris, or San Francisco—people were curious, engaged, wanted to understand what I was building. But in Seattle? Instant hostility the moment they heard "AI."

So what's different between Seattle and San Francisco? Does Seattle have more employee-workers and San Francisco has more people hustling for their startup?

I assume Bali (being a vacation destination) is full people who are wealthy enough to feel they're insulated from whatever will happen.

This person crafts quite the straw man!

> This belief system—that AI is useless and that you're not good enough to work on it anyway—hurts three groups

I don't know anyone who thinks AI is useless. In fact, I've seen quite a few places where it can be quite useful. Instead, I think it's massively overhyped to its own detriment. This article presents the author as the person who has the One True Vision, and all us skeptics are just tragically undereducated.

I'm a crusty old engineer. In my career, I've seen RAD tooling, CASE tools, no/low-code tools, SGML/XML, and Web3 not live up to the lofty claims of the devotees and therefore become radioactive despite there being some useful bits in there. I suspect AI is headed down the same path and see (and hear of) more and more projects that start out looking really impressive and then crumble after a few promising milestones.

They are extensive.

Death and suffering by other road users. It should be obvious to anyone with a working moral compass that nobody should die just because someone wants a larger car, or wants to go faster, or wants to drive under the influence – or simply has to drive because there are no better options.

Direct monetary costs to the society caused by said deaths and injuries inflicted.

CO2 emissions rapidly making the entire world a worse place to live for generations to come, with the death toll likely being in tens of millions as a conservative estimate. Climate refugees will number in hundreds of millions if not billions. Traffic emissions are dropping very slowly compared to other big sources, and that's almost entirely because of private cars and the political difficulty to regulate driving anywhere near enough even in less car-brained societies.

Particle emissions, including tire and brake dust. These affect the health of billions of people and cause countless premature deaths annually. Dust is flushed into water bodies, causing ecological damage. EVs are heavy and wear down tires and road surfaces much faster.

Noise emission, which is a real, recognized health hazard and a cause of stress. EVs still have wheel noise, which is a major noise component in urban areas.

Direct healthcare costs to the society caused by inactive sitting-based lifestyle. Car-friendly infrastructure is actively hostile, not just indifferent, to active modes of transport.

Direct costs to the society incurred by dark, paved surfaces and a lack of canopy coverage because cars need space. This can have an alarming effect on urban temperatures, increasing the need for cooling solutions and, in the absence of such, contributing to the hundreds of thousands of annual heat-related hospitalizations and deaths.

The costs of building expensive new car-centric infrastructure are externalized to everybody. Toll roads are rare. Taxes on gasoline are nowhere near high enough to cover all the externalities even in Europe. Driving is subsidized by the society, which is economically incredibly inefficient.

---

While we're at it, let's go over the main opportunity costs as well:

Indirect costs to the society by deaths and injuries in the shape of healthy work-years lost.

Indirect costs to the society caused by inactive lifestyle in the shape of healthy work-years lost. When you count both direct and indirect costs, spending money to encourage people to bike and walk, for example by building safe infrastructure, ends up saving money in the end.

There are vastly more economically sane uses for all the extra space that cars need in urban environments where land is valuable, including a wasteful number and width of lanes, streetside parking, parking lots, and parking garages.

Vast amounts of money have been, are being, and will be spent on road infrastructure that could be used on vastly more efficient modes of transport such as rail-based transit.

I don't see it that way. Tabs, spaces, curly brace placement, Vim, Emacs, VSCode, etc are largely aesthetic choices with some marginal unproven cognitive implications.

I find people mostly prefer what they are used to, and if your preference was so superior then how could so many people build fantastic software using the method you don't like?

AI isn't like that. AI is a bunch of people telling me this product can do wonderful things that will change society and replace workers, yet almost every time I use it, it falls far short of that promise. AI is certainly not reliable enough for me to jeopardize the quality of my work by using it heavily.
by beloch | 2025-12-03 20:34:11+00:00
The full quote from that section is worth repeating here.

---------

"If you could classify your project as "AI," you were safe and prestigious. If you couldn't, you were nobody. Overnight, most engineers got rebranded as "not AI talent." And then came the final insult: everyone was forced to use Microsoft's AI tools whether they worked or not.

Copilot for Word. Copilot for PowerPoint. Copilot for email. Copilot for code. Worse than the tools they replaced. Worse than competitors' tools. Sometimes worse than doing the work manually.

But you weren't allowed to fix them—that was the AI org's turf. You were supposed to use them, fail to see productivity gains, and keep quiet.

Meanwhile, AI teams became a protected class. Everyone else saw comp stagnate, stock refreshers evaporate, and performance reviews tank. And if your team failed to meet expectations? Clearly you weren't "embracing AI." "

------------

On the one hand, if you were going to bet big on AI, there are aspects of this approach that make sense. e.g. Force everyone to use the company's no-good AI tools so that they become good. However, not permitting employees outside of the "AI org" to fix things neatly nixes the gains you might see while incurring the full cost.

It sounds like MS's management, the same as many other tech corp's, has become caught up in a conceptual bubble of "AI as panacea". If that bubble doesn't pop soon, MS's products could wind up in a very bad place. There are some very real threats to some of MS's core incumbencies right now (e.g. from Valve).

My bet is on that there will be some kind of interaction of the metal catenary in the environment and maybe causing friction in the cables and shorts, which no one thought of since 1890 when they chose wood due for its insulating properties.

Then they will have to replace the metal with some fancy plastic one, because you can’t just admit the wood was better after all, but the plastic will also be unsuitable and degrade quickly which will ultimately end up with going back to wood in another 10 years. But that wood will then only last a fraction of the original wood, because we do not have old growth wood anymore and all the pine plantation wood won’t last a similar 130+ years.

So after about $3 billion dollars in costs and another $5 billion in economic and lifestyle impact after 20 years, they’ll declare it all a wonderful success, even though the wooden catenaries will live on as art or interior decor for another 200 years.

If we’re lucky, the death toll will even be low.

My entire being is anthithetical to this type of gatekeeping.

> You expect the players of the game to learn the rules before they play.

TFA is literally from a 'player' who has 'learned the rules' complaining that the papers remain indecipherable.

> You expect the players of the game to learn the rules before they play.

Actually, I expect to have to teach rules to new players before they play. We are different.

> int bar(int num) { return num / 2; } > > Doesn't get optimized to a single shift right, because the that won't work if num is negative.

Nit: some might think the reason this doesn't work is because the shift would "move" the sign bit, but actually arithmetic shifting instructions exist for this exact purpose. The reason they are not enough is because shifting provides the wrong kind of division rounding for negative numbers. This can however be fixed up by adding 1 if the number is negative (this can be done with an additional logical shift for moving the sign bit to the rightmost position and an addition).

Sure. I had a lot of help from Claude Opus 4.5, but it was roughly:

- Using pyscenedetect to split each video on a per scene level

- Using the decord library https://github.com/dmlc/decord to pull frames from each scene at a particular sample rate (specific rate I don't have handy right now, but it was 1-2 per scene)

- Aggregating frames in batches of around 256 frames to be normalized for CLIP embedding on GPU (had to re-write the normalization process for this because the default library does it on CPU)

- Uploading the frames along with metadata (timestamp, etc) into a vector DB, in my case Qdrant running locally along with a screenclip of the frame itself for debugging.

I'm bottlenecked by GPU compute so I also started experimenting with using Modal for the embedding work too, but then vacation ended :) Might pick it up again in a few weeks. I'd like to be able to have a temporal-aware and potentially enriched search so that I can say "Seek to the scene in Oppenheimer where Rami Malek testifies" and be able to get a timestamped clip from the movie.

BSD-0 is a public-domain-equivalent license. The guy who published it is one of the few people who has actually been involved in a lawsuit to try to assert a copyleft license. The whole thing was such a bad experience for him that he decided copyleft licenses are a false goal.

You should watch his talk:

(He used to be a maintainer of busybox, a GNU clone for embedded devices. He then ended up writing toybox, a similar project under the more free MIT license.)
Show HN: I built a dashboard to compare mortgage rates across 120 credit unions
by mhashemi | 2025-12-03 20:35:27+00:00
When I bought my home, the big bank I'd been using for years quoted me 7% APR. A local credit union was offering 5.5% for the exact same mortgage.

I was surprised until I learned that mortgages are basically standardized products – the government buys almost all of them (see Bits About Money: https://www.bitsaboutmoney.com/archive/mortgages-are-a-manuf...). So what's the price difference paying for? A recent Bloomberg Odd Lots episode makes the case that it's largely advertising and marketing (https://www.bloomberg.com/news/audio/2025-11-28/odd-lots-thi...). Credit unions are non-profits without big marketing budgets, so they can pass those savings on, but a lot of people don't know about them.

I built this dashboard to make it easier to shop around. I pull public rates from 120+ credit union websites and compares against the weekly FRED national benchmark.

Features:

- Filter by loan type (30Y/15Y/etc.), eligibility (the hardest part tbh), and rate type - Payment calculator with refi mode (CUs can be a bit slower than big lenders, but that makes them great for refi) - Links to each CU's rates page and eligibility requirements - Toggle to show/hide statistical outliers

At the time of writing, the average CU rate is 5.91% vs. 6.23% national average. about $37k difference in total interest on a $500k loan. I actually used seaborn to visualize the rate spread against the four big banks: https://www.reddit.com/r/dataisbeautiful/comments/1pcj9t7/oc...

Stack: Python for the data/backend, Svelte/SvelteKit for the frontend. No signup, no ads, no referral fees.

Happy to answer questions about the methodology or add CUs people suggest.

This reminds me of the recent SvelteKit Remote Functions GH discussion:

> Even in systems that prevent server functions from being declared in client code (such as "use server" in React Server Components), experienced developers can be caught out. We prefer a design that emphasises the public nature of remote functions rather than the fact that they run on the server, and avoids any confusion around lexical scope. [0]

> B) Something happens and kids record it aka school fight videos.

A friend's kid got in a small amount of trouble for something along these lines. He was "present at but not involved in" a fight at school, where some of the other kids were shooting it on their phones.

Then one of the teachers came round the corner to break it up and take the guilty parties off to the headmaster's office.

My mate's son, kind of similar thinker to his dad, clever guy, bit of a windup merchant, sprung into action.

"OKAY, CUT! Right, you and you - " pointing at the antagonists " - reset please, everyone else places right now please, " and rounds on the teacher "... and you can be here but you have to be out of my shot."

There's no way to prove they weren't trying to make a film. There was a note home from the school that basically said "We know he's at it, we just can't prove he's at it, but we do know that he's not going to do that again, right?"

Most of the people against “AI” are not against it because they think it doesn’t work.

It’s because they know it works better every day and the people controlling it are gleefully fucking over the rest of the world because they can.

The plainly stated goal is TO ELIMINATE ALL HUMAN EMPLOYEES, with no plan for how those people will feed, clothe, or house themselves.

The reactions the author was getting was the reaction of a horse talking to someone happily working for the glue factory.

> For instance, the fact that the laws of physics are the same today as they were yesterday and will be tomorrow — a symmetry known as time translation symmetry, represented by the Lie group consisting of the real numbers — implies that the universe’s energy must be conserved, and vice versa. “I think, even now, it’s a very surprising result,” Alekseev said.

As somebody who has lived in Seattle for over 20 years and spent about 1/3 of it working in big tech (but not either of those companies), no, I don't really think so. There is a lot of resentment, for the same reasons as everywhere else: a substantial big tech presence puts anyone who can't get on the train at a significant economic disadvantage.

It's not a fool's errand. You are underestimating how few games most of Steam user's playtime is in. Getting proper support for ARM to make out the most performance on the most popular titles is a reasonable thing to fund. Valve can still use FEX for addressing the long tail of games, but it will have disadvantages to a proper ARM port.
