Show HN: FomoRobo – AI that reads your newsletters so you don't have to
by everyseccounts | 2025-09-30 21:17:32+00:00
I subscribe to dozens of newsletters and didn’t want to miss key insights, so I built an AI that reads them all and lets me ask questions about the content. I originally built it for myself, but decided to open it up in case others find it useful.

Forward your newsletters to FomoRobo, and the AI will summarize the important points. Ask it questions like "What are the key facts from my newsletters today?" or "Write a blog post based on today's newsletters."

The tricky part was making email parsing reliable and keeping conversation context across newsletters.

It’s already processing 100+ newsletters a day. Would love feedback, especially on the UX and on what other newsletter-related pain points you would want solved.

Thanks!

That's an excellent question and has a lot of nuance to it. In principle there's ~200 countries in the world, and most of them have their own currency, which leads do 200^200 = 40_000 exchange rates in the world. More even; most currencies have wildly different exchange depending on what exchange you are actually using and how much liquidity that exchange has.

In practice, most currencies are actually liquid against the American dollar; and maybe a few other major coins. This is mostly a technical issue, since liquidity is fragmented and it is just easier to trade against what you know everyone else has: the all-dominant US Dollar [1].

Now, enough theory, how do we do it at Peanut?

Currently, all user balances at Peanut are dollarized; that means users hold USD stablecoins. This is a deliberate simplification; in the future, we plan to roll out other stablecoin support (especially important for Europeans. The rest of the world is pretty happy with holding USD).

When we have to do an exchange to a local currency, like Argentinian Pesos, we work with a local exchange provider. They are able to give us the best exchange rate, because we go directly from a USD-like stablecoin (USDC or USDT usually), to their currency.

For them, USDC & USDT are functionally equivalent to hard cash, and they price it accordingly. They also get it IMMEDIATELY; they don't have to wait multiple days until settlement and until we wire them the funds from some American or European Bank. This is much better for us than for other fintechs like Revolut or Wise; they have to have their own liquidity (and all the infra, compliance, and legal that that entails!)

In the future, I expect our exchange rates to get even better. As foreign exchange continues to grow ON chain, liquidity on chain will increase; until it is the largest (and thus CHEAPEST) exchange in the world.

[1] Note: with the slow end of Pax Americana under the current US regime, the adoption of US Dollar has actually been falling somewhat; replaced by sovereign nations and funds actually holding more gold instead of usd . That's also why we've seen gold at all time highs

This is a good question.

Inflammation broadly refers to destructive immune activity (or sometimes any immune activity). If you get a cut, immune cells show up, they kill germs, sometimes they kill somatic cells too. Different cells show up to heal and close the wound. That's all immune activity.

When you need it, it's a net good, but you don't want any of that going on when you don't need it. Increasingly people seem to have more immune activity than they should and it causes cumulative low grade damage. That's the "systemic inflammation" that you've probably heard about.

hs-CRP (high sensitivity C-reactive protein) is a test which seems to be a good biomarker for systemic inflammation, although CRP is just one chemical involved in immune activity. This article is advocating for using that particular biomarker (related to systemic inflammation) to predict heart disease.

Sorry for the delayed response!

The main thing was wrestling with the instrumentation vs the out of the box langfuse python decorator that works pretty well for basic use cases.

It’s been a while but I also recall that prompt management and other features in Phoenix weren’t really built out (probably not a goal for them, but I like having that functionality under the same umbrella).

You'd get most Democrats to support voter ID if it came with a national ID card, plus an affirmative duty to some agency to ensure that everyone has access to one.

We have neither of those things. The closest we have is driver's licenses, because our culture is such that everyone eligible wants one. The only broadly available federal photo ID is the passport.

Requiring a driver's license, passport, or equivalent is unconstitutional, though. This is because even non-driver equivalents cost money in most places, making it an unconstitutional poll tax. That's why even the places with strict voter ID laws allow really strange forms of identification - they rely mostly on people not knowing this.

This may be, but not, I think, in a way that is particularly worth modeling?

When we try to model something probabilistically, it is usually not a great idea to model the probability that we made an error in our probability calculations as part of our calculations of the probability.

Ultimately, we must act. It does no good to suppose that “perhaps all of our beliefs are incoherent and we are utterly incapable of reason”.

It depends. Often staff are a lot more even handed than volunteer editors because you have to be a bit weird and love moderating to do it voluntarily, but it's pretty normal to do it as a job.

StackOverflow has this problem (or had, before it died) - the mods were hugely invested in closing questions for basically any reason, so normal users ended up hating it and the company couldn't make any changes to improve things because whenever they tried the mods revolted.

It's not as much of an issue with Wikipedia because most Wikipedia users aren't actually editing articles and running into any moderation issues.

What a boatload of crap.

> Statins can be beneficial in patients who have already suffered heart attacks. Cholesterol lowering is not the reason for the benefit of statins. If it was, lowering cholesterol via any means should have produced the same benefit, but it doesn’t.

What a blatant lie! Ppcsk9 inhibitors have produced excellent results, even better than statins.

I hate this take. Duolingo users understand fully, once they clear their language's Section 3 or higher, that they have a long road ahead.

The point of Duolingo is to be a hook into language learning, not a complete replacement. It should be coupled with Pimsleur and other traditional study methods if one is truly serious about learning a language.

Would you rather have teens shitposting on TikTok or learning Duolingo? Posts like yours are doomer cringe.

On a 19 x 19 board the ranks are traditionally determined by the handicap needed to give an even game. So a 14 kyu would give 20 - 14 = 6 stones to a 20 kyu. 20 kyu is a rank that often sees rapid improvement, as the basic ideas "click" just through play and experience. You might be stronger than that now.

Handicap stones give a greater advantage on smaller boards, but 19 x 19 is the standard size. I've not seen any specific guidance for smaller boards.

The 770 and Maemo environment were pretty amazing back in the day - high resolution screen for the time, but a somewhat laggy interface given the compute available at the time. Hardware was somewhat compromised - the half-height MMC storage expansion was particularly difficult to find. I still have one sitting around somewhere.

It did support touch, with a stylus built in - I forget if the stylus was needed or if you could use your bare fingers.

Unfortunately, it's an arms race of cheating. Everyone else was the president of 5 school clubs, volunteered at a soup kitchen and animal shelter for 2 years, tutored disadvantaged kids for 4 hours a day, was a varsity athlete in 3 sports, played the trombone in band, and won 10 academic awards... so everyone has to say that in order to at least seem like an average candidate to college admissions.

I have an X-T3 and I love it. I went from an X-E2, to a Sony set up, and then quickly went back to Fuji. There's just something about Fuji that made it more enjoyable to shoot, for me (mostly travel photos).

I will say the only thing that gives me FOMO is the lack of the Classic Negative film sim, as a lot of recipes that I see online that I really like uses that film sim as the base.

If what appeals to you about Fuji's are the recipes and film sims, I'd make sure to research which ones you like, and then work out which model has the film sim you need to recreate it.

I walk my kids to school every morning. And I walk to pick them up. It's a 10 minute walk to get them, so that's about 40 minutes of walking each day. I could drive and get there in 2 minutes then wait in a line. It would probably cut the time in half, but walking is better for the environment (noise, pollution, safety, wear and tear), me, and my relationship with the kids (we, y'know, talk while we walk).

There's people that live even closer that drive their kids to school. One of them lives literally 19 houses down the street from it.

I also have a rule where if I can go somewhere within 20 minutes on a bike, I'm taking my bike. Most places I go fall under this rule, and I live in what most would call a suburban hellscape.

My wife used to drive to work. Driving took longer than walking. But she still drove.

I think it's less about easy vs hard and more about the culture around driving in the US.

It is a great example of "objectivism" where on the surface it seems neutral and rational but actually is the subject of intense motivations that corrupt the content. This is particularly true for anything related to politics, history, nation states, celebrity tech bros, and so on. An average article on "the history of bicycles" is not a problem and not what I am referring to ofc.

For a different reason it is host to a wide range of superficial treatments of scientific and medical information. Which is not ideal. See scholarpedia for a better alternative for this kind of information (although its not well populated).

I invite you to search HN for 'libor' and see how many of the American users of this website were affronted by the vast fines dished out by the US government to UK-headquartered banks for manipulating the LONDON Interbank Offered Rate from their offices in London, UK. If you can find a single one I'll eat my hat.

Microcontrollers with floating point hardware are very expensive (60¢ and up) compared to microcontrollers without (3¢), and since the 01980s, software floating point has been plenty fast enough to use in pocket calculators, even on the slowest microcontrollers available.

To be somewhat concrete, on amd64 with valgrind --tool=callgrind my non-BCD decimal fixed-point RPN calculator program https://gitlab.com/kragen/bubbleos/tree/master/yeso/rpncalc.... compiled for the console (rpncalc_linux.c) takes 228,141 instructions to process the input "2 3q" from the keyboard, and 229,824 instructions to process the input "2 3/q", an additional 1,683 instructions for the division, mostly to display the result. Division is probably the worst case for regular arithmetic. An additional division operation takes another 1,601 instructions. A subtraction instead takes 1,563.

On an 8-bit processor like a PIC or AVR, you need to run more instructions to do the same work, but it's typically maybe a factor of 8 for data processing and less for things like looping. So we're talking about maybe 10,000 instructions per keystroke, probably less. On a 16MHz 1T microcontroller, that's less than a millisecond.

You might think that if the microcontroller doesn't have space for floating-point circuitry it also doesn't have space for enough memory for software floating point, but that would be wrong. My decimal floating point library is 1204 bytes (≈602 instructions) compiled for AVR, and the calculator UI logic is 2134 bytes (≈1067 instructions). This fits in all but the smallest microcontrollers. Like, it doesn't quite fit in an ATTiny25.

I had a similar experience, I was a heavy Duolingo user between 2014 and 2016 (I used it for Spanish) and I still believe that back then it was actually a pretty good way to learn the basics and I had learnt enough to be able to get by in Spain, have casual conversations with people, even hang out with a group of natives (but I also was a member of a few WhatsApp groups with Spanish people so I had a bit more practice).

Then they dumbed down the phone app and soon enough they did a similar thing with the website. Tips & Notes section was gone (or they kept it but removed a lot of information? can't remember), the tree-style courses were gone and replaced with some kind of a Path, the exercises became too easy and they'd make you translate from Spanish to English most of the time, which is much easier than the other way around. Then they removed the ability to type with your keyboard, added the "match the word pairs" exercise (which sucks if you use a keyboard and yes, I know you can try to use the numbers on your keyboard), all of which made the whole experience even worse and less effective.

I lost my streak somewhere in the middle of this enshittification process and I've never really gotten back to using the site, other than maybe checking once a year whether it's still shitty (and it always is).

In my opinion, back in 2014 Doulingo used to be a learning website with some gamification aspect that made the learning process a bit easier and more entertaining. Now it's just a gaming app which tries to give you a false sense of learning a language but in reality you aren't learning anything. Just a waste of time.

I certainly didn't mean to imply that Julia's community was incompetent or that they were not doing integration testing. CRAN's approach (which is mandatory integration testing against all known dependents enforced by the packaging authority - the global and mandatory nature being what makes it different) is genuinely innovative and radical. I don't think that's an approach that should be adopted lightly or by most ecosystems, but I do observe that a.) these languages have similar goals and b.) it's an approach intended to solve problems of much the same shape as described in the article.

Again I think this approach is too radical for most ecosystems, but Julia is pursuing a similarly radical level of composability/reusability and evidently encountering difficulties with it, so I think there may be a compatibility there.

This is why, as an engineer, it seems futile to make an ethical stand against something. They'll just find someone else to do it. Early in my career I was asked to write code to cheat a benchmark, essentially to make it seem our software performed better than it really did. I agonized over it because I was a junior developer just starting out my career, and eventually got the courage to tell my manager I wouldn't do it. He said, that's OK and then assigned it to Bob, three cubicles down who didn't have any problem with it and finished the cheat in a few days.

Even with OP's kind of sorting, office chat products conceal the priority of any given message to trick you into more participation. The "purpose of a system is what it does" style thinking can get carried away, but more than 99% of the messages in places I will be expected to notice things that require same day attention, don't. The goal is to waste my time.

I rarely have >3 unscheduled conversations in a day that couldn't wait until tomorrow morning. They just never come from the same place.

It's a yappers paradise. They wouldn't include me on an email where they deliberately have to pick participants, but think the serendipity will occur down the road justifies forcefeeding me whatever bullshit they're working on just in case.

That's exactly a situation where signage is mandatory (and, I think, legally required) to say what the current rule is. The hard-coded traffic law that would apply here is "obey the traffic signs".

The point I was making is that these cars should absolutely not be "learning" what rules to follow by observing what other drivers actually do. When there is no clear signage, there are well-defined laws about what drivers need to do and self-driving cars need to follow those even if human drivers don't.

In the 1980s I read articles in the “science fact” columns in Analog Science Fiction Magazine that told me that NASA sold out a much more ambitious lunar program for something that was little more than a stunt.

The reality was that Von Braun looked at dozens of mission architectures before discovering one that was much more feasible than any of the others and made it possible to realize Kennedy’s dream.

The moon is not far away in terms of miles but in terms of energy and momentum it is very far away if your goal is to fly there and fly back. Right now the best idea we have for a moon lander is to hope that SpaceX gets Starship to orbit and masters orbital refueling it’s not like they can fly 100 tons there and back, but rather they can land about what Apollo did with a much bigger spacecraft that’s really tall and tippy, needs an elevator, can get the ascent rockets smashed on rocks, etc. if they had a set of those chopsticks on the Moon or Mars they could land it easily but on generic inner solar system bodies covered with boulders, craters and stuff good luck. Plan B is basically the same from Blue Origin.

If you could refuel there the math changes, maybe you can, there might be usable ice at the poles but nobody has seen it, unless we have a Drexler machine we’re going to have to launch a huge number of missions with a marginally effective system until we have a system in place that can reliably deliver fuel.

So it’s tough, any honest analysis of space colonization makes you come to the conclusion that Drexler did, rocketry has very little to do with it, being able to pack a self-sufficient industrial civilization into the smallest package has everything to do with it.

I'm sure there are those that have had different experiences, but I've been party to several M&A due diligence exercises (including >$1B) at a large financial and there is *tremendous* pressure (on both sides) to move quietly (MNPI baby), quickly and not destroy your relationship with the acquired entity in the process. The business wants the sale to close, you're looking for issues that could be leveraged in the deal and/or actual show-stoppers. The interactions are clumsy as they are managed through third party portals that keep the data locked down and in escrow. The sell-side entity still has every right to protect their intellectual property until it's parceled in a contract, so you're not going to get access to shit (unless they are stupid I suppose). It's going to be in an audit-like situation where you are going to ask someone for samples (which obviously can be groomed) or doing screen shares and taking screenshots or similar.

The fact that the acquirer is large is somewhat immaterial, the teams 'under the tent' doing the investigation are going to be relatively small on both sides, including folks from the business trying to close the sale, internal/external counsel and singular SMEs from relevant domains.

I'm not sure if anyone else runs into this, but I feel cursed by bad pasta.

Every time I boil it, I inevitably get pasta that is under-cooked in the center while mushy on the outside. I've had some times where I've had to boil it for several minutes more than recommended just to get the inside to cook fully.

And even a few minutes in, the pasta seems to split apart into pieces.

I've tried 'quieter' more simmer-y boils, I've tried cranking it up as far as it goes, I've tried salt, I've tried different stoves, nothing has seemed to help.

Maybe it's just low-quality noodles, I don't know.

> I estimated that they needed over $100m of chips just to do Qwen 3 at max context size

I will point out (again :)), that this math is completely wrong. There is no need (nor performance gains) to store the entire weights of the model in SRAM. You simply store n transformer blocks on-chip and then stream block l+n from external memory to on-chip when you start computing block l, this completely masks the communication time behind the compute time, and specifically does not require you to buy 100M$ worth of SRAM. This is standard stuff that is done routinely in many scenarios, e.g. FSDP.

That's a direct copy of what Midjourney has done already.

https://www.midjourney.com/explore?tab=videos

Many people are just playing with images and the distinctive styles that Midjourney (the model) seems to have developed. It's also trained by ratings and people's interactions.

When you make images you can dial down the "aesthetic".

Because the Software Update page under System Settings is all that normies will ever read and so what's in the text there is focused on normies.

Meanwhile techies may be interest in the CVEs listed in the security update list:
