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 :)replyainiriand 1 hour ago | parent | next [–]
It confounds me why would anyone keep a bird in captivity... Imagine that you have the power to fly and they keep you in a box.replysatvikpendem 0 minutes ago | root | parent | next [–]

"I always wonder why birds stay in the same place when they can fly anywhere on the earth. Then I ask myself the same question." - Harun Yahyareplysatvikpendem 2 minutes ago | root | parent | next [–]
This was always a flawed quote because even before such a realization, people still did novel things (and literally flew to new places), much the same as birds. And the answer is still the same for birds and humans, the constraint of resources. If you have enough then by all means, fly.replyauselen 41 minutes ago | root | parent | prev | next [–]
Good question, if it is such.We keep a rabbit indoors, free roaming in the house, now for 7 years, I expect he will do 10+Would you prefer to live freely for 6 months or have a hopefully comfortable life for ten times more.

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!replymitjam 57 minutes ago | prev | next [–]

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 :)replyjcynix 3 minutes ago | parent | next [–]
Good read thanks. I totally can relate to the choices problem. It's rather easy with physical books (or was, as we have little room left for even more books ;-0) but ebooks are "dangerous" too.Regarding cameras, it's harder (and more expensive) to wrangle with gear acquisition syndrome (GAS) but after switching from Canon EOS to Fuji, because the Canon stuff was too heavy when hiking, I managed to restrain myself most of the time. Because the question always is whether my images would become better with different gear or with more trial and error.I opted for trial and error and eagerly watch a selected number of YouTube channels who almost always show me that I should and can improve myself and not my gear.replyRagnarD 18 minutes ago | parent | prev | next [–]

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!replyspenjovewkwhalo 3 hours ago | prev | next [–]
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.replynicbou 1 hour ago | parent | next [–]

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.replyaaronbrethorst 1 hour ago | prev | next [–]
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...replysjw987 35 minutes ago | parent | next [–]
Interesting. What hardware do you use to measure this?I have a Netatmo home device that measures PPM and have been observing the trend lines throughout the day. At some points my flat gets up to about 1400, which the device says is bad, and sometimes it goes down as low as 500. I've noticed a pattern but can't quite connect that pattern to my activity or the surroundings. It starts going up around 4pm, which could be homewards-bound vehicles, but it seems to trend even on weekends when there is lower traffic. Maybe I start breathing differently at these times. I'm quite interested in getting to the bottom of it. Unfortunately I'm west facing so plant use is quite limited.What is the atmospheric ambient CO2 level? Is that variable based on location?I've learnt a few things:- I had my sensor on my work desk which meant the CO2 pooled, and was increased dramatically by my breathing almost directly onto it. Moved the sensor at least 1.5m- I had the sensor quite low down, where CO2 pools (being heavier), so moved the sensor to eye level- CO2 seemed to increase when cooking (same room), so while cooking I open the windows and let the warmth flow out of the buildingreplyFazebooking 1 hour ago | parent | prev | next [–]

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.replyilinx 4 hours ago | prev | next [–]

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.replyGarnetFloride 4 hours ago | prev | next [–]

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.

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 :)/off dancingreplyFazebooking 1 hour ago | parent | next [–]

Seriously, this is not what big data does today. Distributed query engines don't have the primitives to zip through two tables and treat them as column groups of the same wider logical table. There's a new kid on the block called LanceDB that has some of the same features but is aiming for different use-cases. My trick retrofits vertical partitioning into mainstream data lake stuff. It's generic and works on the tech stack my company uses but would also work on all the mainstream alternative stacks. Slightly slower on AWS. But anyway.

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.replyaqula 38 minutes ago | prev | next [–]

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.replyp00dles 2 hours ago | prev | next [–]

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.replygeuis 2 hours ago | prev | next [–]

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. Aaaarghreplymediumdeviation 4 hours ago | parent | next [–]
Another fun fact - lodash/fp doesn't deduplicate with lodash when bundled. For a couple of months I was wondering why our app had bundled two copies of lodash. I dismissed it as a measurement artifact at first. It took so long to realize there was actually two copies of lodash and it was because one developer on our team had a preference for fp syntax.replyesperent 3 hours ago | parent | prev | next [–]
> lodash-es doesn’t ESM lodash/fpMost of my career has been JS and TS and I have no idea what this means.replysoulofmischief 3 hours ago | root | parent | next [–]
I'm guessing you're only a few years into your web career, so I'll provide some background. lodash is a popular library that fills in many blanks that pre-2015 JavaScript had. It still provides value in modern JavaScript, but it's no longer as important as it used to be.JavaScript is actually based on a standard called ECMAScript. ActionScript shares this standard, as an example. In 2015, we got ECMAScript 5, which modernized JavaScript in many ways. With that came many changes such as ECMAScript moving to a yearly update cadence, in response to the large amount of effort involved in implementing ES5, which came with a ton of changes.One of those changes was ES modules, or ESM, which provided an official way for working with modules. The import/export syntax you're used to is a part of that spec. Before this, we had competing non-standard specifications for module loading, such as CommonJS.ES5 reduced the need for tools such as lodash, and so it's less common in newer projects. It also is old enough to have been around before ESM was adopted, and is a large project, and so like many projects it either had to completely rewrite everything, or use transformation tools such as babel. If not, the user was responsible for using babel/etc to transform the code. Now, in modern stacks, because this is unnecessary, native support for CommonJS is being phased out, leading to OP's conundrum.Now we have TypeScript, and the horrors of JavaScript 10+ years ago are a fading memory.replyesperent 1 hour ago | root | parent | next [–]
Nope, I'm about 15 years in and (unfortunately) deeply familiar with all of that. As someone else pointed out below, it was the use of ESM as a verb that threw me off.Thanks for taking the effort to type out a history lesson though, hopefully someone will benefit from it.replyesperent 1 hour ago | root | parent | prev | next [–]
