Ask HN: What did you find out or explore today?

I found out my crimson-bellied conure is laying an egg today! She's nesting in some towels now, chirping away while she works on laying it.

Having an egg is relatively hard on parrots. I've given her lots of food and warmth to prepare. She is comically hungry -- she's usually not such a big eater, but she's happy today to be scarfing down her apple slices, fruit pellets, and safflower seeds.

She usually sleeps at the bottom of her cage, beneath a towel I put down for her. It's already unusual for parrots! But tonight she has made quite a nest with her towel: It's folded in half like usual, but she has nuzzled her way between the fold, so she has the towel underneath and on top of her. It's super cute.

I'm treating her with delicacy but she is determined to be a wild child of a bird. She's still flying around during the day and moving around plenty. I don't think I would be so confident if I had an egg like that inside me.

She has a stone perch that she likes to nibble on when she's working on an egg. I've wondered if it is some innate need to nourish herself with calcium, or if it's stress relief :)

So that's my night. Sitting outside of the metaphorical delivery ward with a metaphorical cigar, making sure she lays this egg that isn't even fertile to begin with! Birds :)

I live in a condo complex in Florida where the onsite staff at the front desk know me well and they are mostly bilingual and know I’m learning Spanish.

I went up to ask then something and jokingly said “no hablo inglés, ¿Hablas español?” and I was able to carry on a more or less complete conversation with them in Spanish and ask for what I needed without pre rehearsing lines for the first time.

So I found out within the past 24 hours that I can carry on a simple conversation in “survival Spanish”

I got a handheld emulator console as a Christmas gift. Configuring shaders that emulate crt TVs, I realized I had no mental model of how those TVs worked at all.

I’m used to “pixels are three little lights combining rgb colors”, which doesn’t work here, so I went on a rabbit hole and let me tell you, analog TVs are extremely impressive tech.

Getting an electron beam to hit a glass, making the chemicals on it spark, covering it in a “reading motion” for hundreds of lines, and doing that 60 times a second! And the beam is oriented by just careful usage of magnets. It sounds super sci-fi for an already dead, 130 years old technology.

I also learned that my childhood was a lie. Turns out that the logic in consoles of the time was tied to the speed of the beam, which in turn used alternating current’s frequency as a clock. This means that since European current changes 50 times per second rather than 60, our games played in slowmo (about 0.8x). American sonic was so much faster! And the music was so much more upbeat!

I'm doing PHP for the first time in years. I needed a function that returns the date of last week's Monday. Turns out PHP has a funky date querying language. I can just do: $today->modify('monday last week'). Makes me happy.

I have started exploring Seneca/stoicism again. Prompted partly by a recent submission here, partly by personal reasons. Instead of consuming other peoples interpretation of stoicism I decided to go as close to the source as feasible for me. I have read Letters from a stoic a number of times before and my copy is filled with highlights, but this time I think I will try to limit myself to one or two letters a day and then really think about them properly.

The first one really hit me hard and prompted me to write out my own thoughts (https://jesperreiche.com/seneca-letter-2/) whether I will keep doing that I am a little unsure. It feels on the border of how personal I want to be/share on my blog.

P.S. I can see the irony in writing about me going to the source instead of consuming other peoples interpretation and then sharing a link to my own interpretation :)

I learned about this book / concept: Tools for Conviviality [0]:

> Illich proposes the idea of a 'convivial tool', one which allows its user to exercise their human autonomy and creativity.

This came up as I was reading about UX / UI design and trying to understand the fundamentals of how to increase human autonomy. Although my key takeaway is a bit shallow at the moment, mostly focused on applying this map towards existing tools in order to try to identify ways in which they can be modified and improved to maximize autonomy.

The Wikipedia article also references this concept of radical monopoly:

> Tools for Conviviality also introduced Illich's idea of a 'radical monopoly', which describes a technology or service which becomes so exceptionally dominant that even with multiple providers, its users are excluded from society without access to the product.

Which has extended to me wondering about what the world will look like as people are increasingly pushed to use LLMs or other AI tools in more and more interactions. And in particular, what actions can or should be taken to maximize human well-being.

I went on a tour of a miso factory today and learned about how it's made!

What surprised me the most was that shiro (white) miso and aka (red) miso are both the same mix of soybeans, salt, and rice malt but fermented for different periods of time. As the miso ferments for longer, its color becomes darker while its flavor becomes milder and more complex. Beyond 3 years of fermentation, you get diminishing returns as its flavor becomes too acidic.

After the tour, we got to sample some of the naturally fermented 3 years old miso, and it was easily the best I've ever had. Most miso you can buy in a grocery store is created through forced fermentation over a few months, so if you ever get a chance to try naturally aged miso I would highly recommend!

I found out that it is nearly impossible in Europe to buy a 10l enamelled bucket with a lid. I need one for my organic waste, since I found that both metal and plastic ones tend to keep the smell despite cleaning them weekly.

My home office gets up to about 1500ppm of CO2 by the end of the workday, which explains a lot about why I often feel exhausted after the end of a long, uninterrupted session in there (especially when I’m on back to back zoom calls).

I now have several plants in there that are supposed to be especially good at sucking up CO2, and my sensor reports that the current level is slightly below atmospheric ambient CO2 levels.

I also wrote up a blog post about the structure of the Washington state legislature, which began its sixty day session for 2026 earlier this week. https://www.brethorsting.com/blog/2026/01/how-the-washington...

Today I learned about the difference betweeen "preconnect" and "dns-prefetch": https://web.dev/articles/preconnect-and-dns-prefetch

I have thought that they were the same...

The origins of Port and Starboard on ships.

Chosen to be independent of a mariners orientation.

Starboard - most sailors were right handed and the steering oar was placed on the right. Star = steer. Board = side of boat.

Port - as steering oars got bigger, boats tended to dock on the left hand side. This became to be known as “lardboard” which sounded too much like starboard, so it was changed to “Port” (as in the side typically facing the port side.

My day just started but I found out that when I type a message in a MS Teams chat open in Chrome in Mac OS there are three separate independent spell checkers fighting to twist my meaning.

Sorry, no positive news yet. But it's only noon.

I'm exploring adding a firewall to my home network to detect if apps are using my network as residential proxy.

My daughter likes to install random games on iOS that have been advertised to her on other apps, and I wonder if some of those work as residential proxy behind the scenes.

Surströmming, the Swedish can of fermented fish, is strongly recommended to be punctured while submerged in tap water. It is not pasteurized and is actively fermenting in storage, and the content will spray around if opened under atmospheric conditions.

When transported on cargo flights, they are double packed as cans in a barrel in a crate, and considered UN classified "miscellaneous dangerous goods" with identification number UN3334 "Aviation regulated liquid, n.o.s." with accompanying scary(albeit monochromatic) warning stickers, if at all accepted. When transported on ocean going vessels, they are often required to be in its own shipping container, again double packaged and correctly labeled.

Learning how much of a hassle moving house is. Will take me forever to get addresses on all service providers etc moved

Also learning more about mold and dehumidifiers

I've learned that being truthful in your resume as a SWE doesn't work anymore. I've had nearly 0 response rate to my applications, even if I was nearly a perfect match. Dude that we fired a while ago for being abysmally bad and non-productive gets interviews, raises and just got into ycombinator backed company by making up 75% of his resume(which I saw). We need a reset, this is getting ridiculous.

I’m reading Domain Driven Development and learning why so many of my projects have been tough to maintain.

I also recently learned that you can get ancient coins for very little money if you don’t care about resale value or need them to be in pristine condition. I bought some coins from kingdoms that I’d never heard of. Many are thousands of years old! It’s fun holding a piece of history like that.

Set up motion detection on my home security camera. Caught four stray cats playing in the driveway at like 2am. Kind of annoying that the detection is unconditionally "object-based" (ANN is used to filter false positives like lighting changes).

Also been thinking about game ideas for a while. Finally settled on an open world RPG where you control multiple (>10?) characters. Core gameplay loop will be configuring / optimizing schedules (farming materials, grinding xp, etc) and watching damage / currency numbers go big. Though if I'm being honest, I just want an excuse to build something that involves a node-based UI. So even if I don't finish, I'll have at least scratched that itch.

On the command line the `strings` command will list out printable characters in a file (including compiled binaries).

I don't do any systems level programming but found myself down a small rabbit hole of learning about reverse engineering tools. https://github.com/NationalSecurityAgency/ghidra is an open source one. It will show you the assembly code, does its best at giving you a C representation of that code and lets you interactively rename variables and symbols to make it more human readable.

I’ve been slowing crunching through Math for Deep Learning, so spent a fair amount of time looking at Hessian matrices + second order optimisation. I’ve been slowly reading this book for a year, so stopping to do most of the math by hand each time. One chapter to go!

Then I was sick all last week, so ended up down a rabbit hole about the current card collecting bubble (right word?). Super interesting.

We've recently been without water in the UK for 5 days (water company failings). I've come to appreciate mains water and how its utility is hard felt by omission for toilets, washing & cleaning. Immensely grateful to have it back now.

I found out today that the location header of an HTTP redirect can be a tel:+ URI and phone's will actually ask you whether you want to call that number.

Reading up on the history of information management, and the real killer app for paper was double-entry bookkeeping, which made Venice rich and contributed to starting the Renaissance.

I'm building in robotics. Setting up a new 3d camera today. I found that the 10m active USB C cable that I bought transfers power in both directions, but only transfers data in one direction, it turns out to be some weird video USB variant. Next I needed to plug a gripper into a modbus controller. That uses an M8 8-pole 20cm cable. The controller manufacturer recently decided to switch from male to female connector, so now the cable needs to be male-male. After searching online for hours, I believe that is impossible to find as everyone only sells male-female cables.

I'm continuously surprised by how difficult it is to plug things together and how non-descriptive cable "standards" are about the actual capabilities of cables and connectors.

Incorporated a cli AI to my daily work. Just impressive, was working on some networking code, I could think of 100 ways to stress test it, then I ‘prompted’? AI to implement those ideas, found many issues, hangs. Shared agent those, asked it to add prints, retest, improve my implementation. Now I got a good solution in a day. Previously this would take a week at least with my worrying about all the things I could test, improve…

I had some eye strain and think it is because my eye muscles are overused. A doctor told me the muscles in the eye are flat, like tapes, and that I would not feel a muscle ache. I noticed the strain when I focus on different points quickly. I started to pay attention to how I move my eyes and realized I read a lot of text while scrolling, for example reading X posts on mobile while scanning the text at the same time.

Yesterday I was reminded of “Rapid Serial Visual Presentation” for speed reading, where the words are presented so you do not have to move your eyes. I am currently trying it out with a Chrome extension called SwiftRead. I set the text size so it fits into my fovea area. I used a fovea detector website I saw on HN a while ago: https://www.shadertoy.com/view/4dsXzM (make the pattern full screen, then you can see the size of your fovea).

I also learned that I can reduce some of the strain by moving my head more toward the things I am looking at on the screen.

I had a great euphoric epiphany feeling today. Doesn't come along too often, will celebrate with a nice glass of wine :)

Am doing data engineering for some big data (yeah, big enough) and thinking about efficiency of data enrichment. There's this classic trilemma with data enrichment where you can have good write efficiency, good read efficiency and/or good storage cost, pick two.

E.g. you have a 1TB table and you want to add a column that, say, will take 1GB to store.

You can create a new table that is 1.1TB and then delete the old table, but this is both write-inefficient and often breaks how normal data lake orchestration works.

You can create a new wide table that is 1.1TB and keep it along side the old table, but this is both write-inefficient and expensive to store.

You can create a narrow companion table that has just a join key and 1GB of data. This is efficient to write and store, but inefficient to query when you force all users to do joins on read.

And I've come up with a cunning forth way where you write a narrow table and read a wide table so its literally best of all worlds! Kinda staggering :) Still on a high.

Might actually be a conference paper, which is new territory for me. Lets see :)

I've been exploring kefir. I'm looking at finding some live grains to boost the store bought variety here (10-20 varieties) up to 50-60 varieties or so, like the kefir in Eastern Europe / Russia. The store bought stuff in my country (UK) is more like a diluted, gimmicky thing. However, I believe the strains of bacteria they do include are some of the more influential ones. I think it would just be interesting to expand the scope a bit.

This came from reading about the gut microbiome, which was spun off from reading a book about Ultra Processed Foods (Ultra-Processed People). I've been trying to remove UPF foods from my daily consumption, trying to lower the ratio of them I eat (the average is supposedly 60% for adults in my country), since the academic link between UPF and dementia is quite strong now. It's quite shocking to see just how much of a typical supermarket/food store is UPF, and where many of the emulsifiers and preservatives come from.

End of the day for me, as usual trying to walk around as much as I can with my partner, with the hopes to stumble upon stuff. Just found a great pasta spot, followed by a watering hole. Grateful to live in this city! Hope you guys are having a good one as well.

I found just now that my telecom operator - Airtel - randomly subscribed me for OTT services and charged me for it. But upon calling them and contesting, they just asked if I want to unsubscribe and then reverted the charges. No threats, pleading, or back-and-forth involved from either side. Mildly surreal.

I wonder that's a new corporate strategy - charge randomly till someone goes through the pain of IVR and spends 15 mins with support. Must generate quite an upside for them if it is indeed a strategy.

I now know that in Italian I should say 'mi piacciono' to convey my liking of things (plural), e.g "mi piacciono i libri" means "I like books", as opposed to singular 'mi piace il libro' (I like the book).

When I refer to likes of multiple people, e.g. "we like this book", I should use "ci piace il libro". Plural people speaking about liking plural books would be "ci piacciono i libri".

One of my goals for 2026 is to reach level B1 in Italian language.

Plumbing together stuff so that the files from a service that can only push to sftp server end up delivered in a Dropbox folder.

I've been exploring the origins of the 'relational turn' in psychoanalysis that began after WWII and ramped up in the 1970s. Psychoanalysis got vastly more interesting after Freud and I had no idea!

When you use a microscope to magnify something, the objective (magnifying lens) is literally taking the Fourier transform of the image. The optical system recovers up to a limiting frequency, determining the spatial resolution of the image.

Today, and yesterday, I've been poking about the history of what was once the longest steam powered fresh water pipeline in the world

https://en.wikipedia.org/wiki/Goldfields_Water_Supply_Scheme

I'm looking into rennovating a massive agricultural machine shed ~ two stories high in the middle built some 80+ years ago using sections of spur pipeline as central upright poles to hold up some beefy jarrah trusses.

The "verandah" wings flaring out from there were bulit from flimsier timber that's rotting and the iron sheet walls are starting to peel away.

The posts are of interest as they have old markings and water fittings, tee pieces, etc.

It's not far from one of the original steam powered pumping stations that moved water through the main line.

Exams in a week! I found out that it's actually pretty easy to fill an entire 150 page notebook with rough work in <2 days.

Welp I'm going through my folder of notes on publishing type stuff - site generators, hosting providers, headless CMSs, all-in-one platforms, etc. First time seeing it all at the same time and being able to compare features/workflows etc.

I found out that the adhesives I've encountered from time to time that remain tacky and easily moved or removed are called "non-hardening" adhesives. This was after using E8000 glue for a headphone repair today.

I was reminded of the US Constitution's 10th amendment and reading some of the history around it.

> The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.

Very relevant to what's going on today with National Guard and ICE deployments.

I’m learning about the “era of the nations” thinking from Hungary’s Balázs Orbán, via an episode of a podcast called the Winston Marshall show. YouTube just randomly suggested it to me.

I just rebuild a speed queen dryer that broke with spare parts from Amazon, which revealed a remarkably simplistic engineering. Very surprised by how simplistic the mechanism was. It’s incredible how over engineered most laundry systems have become.

Also spent some time digging into the integrations between Tesla FSD and rideshare services today. It’s remarkable how much progress has happened.

Was reading about version control history and found out Git went from first commit to self-hosting in like a week. Linus was just mad about the BitKeeper licensing thing and hammered it out. Not some grand architecture - just "screw this, I'll do it myself." And somehow that became... everything. Wild.

That the FOSS bazaar broke off into megachurches while still maintaining a healthy small scale and independent bazaar [0]. That FOSS sustainability is much more complicated than just "throw money at it".

That there's "metal paste" [1].

That the zodiac killer's messages have been cracked for five years now (I didn't know they were cracked to begin with) and that it was a shift and substitution cypher [2]. The telltale clue was that the symbol frequency was uniform but under shift it become non-uniform.

How to solder those pesky connectors that come on the tiny servo motors you can get from Aliexpress [3].

That Firefox only has 2.3% market share [4].

Multiscale 3d truchet patterns are freakin complicated [5].

That prioritizing tasks by the linear combination of priority and effort remains a good strategy.

Not strictly today. But I discovered that there exists a special class of algorithms that are designed with the use case of streaming data to your program. I just used one to get a uniformly distributed sample from a 10Gb log file.

I knew this was something coding interviews delved into: "if it doesn't fit in memory", but until like yesterday I never went down the rabbit hole. I have to say it was a nifty trick.

That running and taking cold showers really do make me more focused! And that i will have to be the one that fixes my life and builds my future. Deep, i know

I explored the programming language nim a bit deeper for use in game programming with SDL3 bindings, but I came to find out that compiled nim code on Windows often triggers anti-virus because, from what I hear from people, nim is used a lot in malware development currently. Which is a shame because I really like that language. I haven't tested it myself, it's just things I have heard and read. Someone on r/gamedev told me to write the code in nim, generate C code and then compile it with zig cc.

If anyone has any experience with this, please do chime in :)

I've explored various VPN settings/configurations/protocols to see what works best with my ISP that tends to throttle traffic to my work VPN.

Some things work OK, but still not as good as commercial VPN providers.

Talking to insurance agents I realised, they don't bother to read the policy documents and have a very superficial knowledge of the policies they are selling. You can glean lot more information feeding the docs to an LLM and asking questions.

Been working on sheet cutting optimization for https://measuretocut.com today and it sent me straight down the cutting‑stock / 2D bin‑packing rabbit hole. What started as “wouldn’t it be nice if the site could tell you how to cut your wood sheets optimally?” turned into reading about NP‑hard problems and flipping through old operations research papers like I was cramming for an exam.

The funny part is how far the mathematical version of the problem is from what measuretocut.com actually needs to output. In reality you have kerf, ugly offcuts, and the fact that nobody wants a cutting diagram that looks like a circuit board. We really have to take into consideration a 2nd optimization, it needs to be an output that a person in a shop can glance at and immediately understand.

Recently procured an AirGradient air quality monitor and set up the build environment so I can customize its reporting capability and perhaps add some different sensors. Also didn't realize how much CO2 builds up during the night in my bedroom. Will have to mitigate this as I believe this contributes to my poor sleep habits.

I've been working on a litle raspberry pi pico project with kafka. As someone that used to have an Arduino uno, it made me genuinely shocked at how small controllers have gotten and they're massive capabilities

setup a desktop with n8n, ollama, open webui, comfyui, and aider. work is dragging it's feet on AI orchestration and workflow tooling so figured I learn it a bit to get ahead of things. just need some personal projects that are interesting enough that I'll pour time into them.

Today I took the subway at a different time than I normally do, and I saw a very different mix of people. Fascinating.

I learned that the large tree near where I live in London that has visibly grown in the last year is a Coast Redwood (a.k.a. California Redwood, a.k.a. Sequoia) and that there are half a million of them in the UK.

Loving this post.

I am in Mexico City and I learned quite a bit about Santa Muerte. Hard to know how much truth there is in what the locals tell me but supposedly people who live in such dire conditions they feel closer to death than to life pary to Our Lady of Holy Death for protection.

Wikipedia says it is the fastest growing religion in the world.

Published an edit today (post dated in Nov. but I've rewritten it 5x now) on my tutorial to use llama3.2:3b to generate fine tuning data to train tinyllama1.1b https://seanneilan.com/posts/fine-tuning-local-llm/ It took a while to figure out that when I made llama3.2 generate json, it didn't have enough horsepower to generate training data that was varied enough to successfully fine tune llama1.1b! Figured that out :) Something you never learn with the bigger models. Every token costs something even if it's a little bit.

Screws weren't standardized until ww2. And even then, they really haven't been.

I learned that my fav part of Apennines is famous for a lack of light pollution and thus is an astro-tourism target. Never paid attention to that aspect.

I also learned that on Aug 12th this year a total eclipse of the sun can be observed from certain parts of Spain.

That I promised my boss to check the office fridge for what we need for the team breakfast and forgot about it.

Also that Newfoundland has a pretty unique music tradition, that captures what irish music sounded before the Great Famine

I explored the space of valid Spelling Bee puzzles and found out the lowest scoring puzzle is (x)bejkou with 14 points.

Hoping they do it for April 1st one year.

Learned about superheterodyne receivers. Recently I've been studying up on RF technology, happened to come across superheterodyne receivers a short while ago, decided to research them today, saw that Technology Connections had a video on them, watched it, and felt reasonably enlightened.

I am deep down into the rabbit hole of assessing various open source projects to build a custom trackball with a 52mm billiard ball (appropriately, it’s the 8-ball).

I'm exploring writing a point and click adventure, and I've found out that they're basically just hierarchical state machines with a pretty UI. This is useful because it simplifies a lot of things.

The downside is that now I'm wondering if I could write one in SQL.

That lodash-es doesn’t ESM lodash/fp, which means there is no straightforward way of using it with Vite after version 5. God help me.

I don’t even want to use it, I just want to get legacy code building on a modern version of Vite without rewriting a couple thousand lines of code. Aaaargh

I found out I can automate my 5,12kWh house battery through local-only RS485 connection, and directly setting registers using ModbusTCP from Home Assistant. I then drafted an automation with hysteresis and damping that tries to aim for Net-Zero export/import (pv surplus/grid). It appears to work!

I am cleaning up some pointer arithmetic stuff for multi-dimensional C style arrays. I managed to replace the code with a std::inner_product minus a std::accumulate (to accomodate for the fact that the upper array bound is exclusive, ie one-past-the-end).

I found out that the guy who broke the thing I was working on was… me.

Found out about finding timing of http requests https://susam.net/timing-with-curl.html

An intern had trouble with an outdated exercise in Elixir that use an old version of an Erlang dependency, so we got to figure out how to depend on a local copy, dig into the Erlang code and do a little hack to make it work.

Basically it relied on a checksum algorithm that was previously in yet another external library but was now in the standard library so that call needed to be updated and variables carrying around the old external library had to be underscored out.

It was a good lesson in traversing error messages and going from an angry VM step by step to a clean success. Not to hairy for a junior to understand when explained, and also not too time consuming to burn out interest, while still a bit of a challenge.

I've been trying to research drone navigation tech from what we have learned so far from the russian/ukraine war. I'm very much not a hardware guy but software by itself has been feeling kind of useless or even crueler than usual.

I've read the adverserial attack paper, and I'm currently implementing a captcha based on images that have masks on them so that any LLM agent with a visual model will classify it wrong.

The idea is to use something like a slider that shows different images combined with a memory task, like "find out the pair of images" and then offer maybe a text input field where the user has to write 1,2,3 or something similar with the image numbers to pass the captcha.

The tldr is that I'm abusing the famous panda image that's classified as a gibbon as a technique to build a bot captcha.

I found git worktree today.

I found out more ways in which our entire socio-economic system is a scam. I literally learn something new about this every day.
