rpozarickij··on ChatGPT Pro 500
On the plus side, it'll be easier to compare these new plans than what we have with all the models.

It looks like they have literally chosen the most straightforward sounding plan names they could think of.

rpozarickij··on Dots: Always-on agents
There used to be Bard but no one remembers it anymore (although this is a bit different, because Bard wasn't nearly as well known as Gemini).

I'm really curious if OpenAI wanted to adopt a different name at some point. Or maybe they hope that sometime in the future one of their products will supersede ChatGPT and everyday people will start using that new name for everything AI so maybe they aren't in a rush to rename ChatGPT itself to anything else.

rpozarickij··on How Delhi cut electricity loss from 50 to 5 percent
Interestingly, this page seems to contain data only until year 2014, but the graph next to Estonia in the grandparent link does show an increase on the right side. Maybe Estonia did indeed experience some changes in overall distribution loss in recent years?
rpozarickij··on How Delhi cut electricity loss from 50 to 5 percent
> Albania, Argentina, Bangladesh, Brazil, Estonia, India, Kenya, Pakistan, Sri Lanka, Uganda, and Venezuela

Even if Estonia does have stated electricity distribution loss, it still looks so way out of place in this group of countries by so many criteria. I wonder why not pick Egypt or Libya given that they have the same distribution loss.

Edit: this could be the reason - when you click on "Map" above the graph, for some reason Estonia is one of the blue countries shown on the map. Argentina, Brazil, and Kenya are there too (but not others).

rpozarickij··on What is the size of Yemen? (2024)
Although I do hope too that people don't lose their sense of meaning and curiosity too much, it's worth keeping in mind that this article was published in 2024 which was a very different world from now. Curiosity requires energy, and it'll be hard for a creature relying on energy for survival to justify using their own energy for some activity when there's a more energy-efficient way to reach a specific goal. But just like going to the gym makes your body healthier despite the fact that this requires energy, thinking on your own will be increasingly important for maintaining a healthy mind and the sense of self.
rpozarickij··on Samsung is expected to more than double output of its HBM4 and HBM4E DRAM
I wanted to mention AWS Snowmobile [0], but after looking it up I found that apparently it was discontinued [1]. It seems that nowadays there are more economical/efficient alternatives (I guess theoretically you could still beat these alternatives in certain metrics, e.g. by using more trucks at once to get more bandwidth).

rpozarickij··on Attention is all you have
> verify you're a human

There could be a technology that cryptographically ensures that each letter/character came from a physical keypress/touch from a human when you want to interact with a human online in written form, but then again a robot could also be pressing the physical switches or interacting with a touchscreen. Perhaps this technology could handle copying/pasting too as long as the text originally came from a human.

I hope we'll develop more robust mechanisms for detecting non-human generated content (including text) that aren't only enforceable by law (e.g. labeling AI-generated content in the EU). Apple Reference Image is one of the steps in this direction.

rpozarickij··on Dropbox's Jan 1st 2027 terms of service
> Your account may be terminated if you don't have a Paid account and haven't accessed for 6 months

I hope file sync is treated as "access", otherwise this would make me anxious.

rpozarickij··on Intelligence per Watt: Measuring Intelligence Efficiency of Local AI
> During the winter time the GPU also doubles as a 300W in-house heater

There could be a service that works in reverse where if someone needs a heater for a few months, they could rent a portable server (e.g. using older repurposed GPUs) with a built-in 5G modem that would run inference on LLM queries. As an incentive perhaps renting itself could be free (or you could earn money?), but you'd still have to pay your electricity bill.

rpozarickij··on Mullenweg has returned as CEO after attempted board ouster
A fun fact about another well known company - Foxconn. Apparently the founder Terry Gou came up with this name by joining words "fox" and "conn". Fox is an animal he liked and "conn" refers to connectors (which is what the company specialized in in its early days).
rpozarickij··on Muse – Meta’s personal AI agent
I've seen people using "chat" to refer to ChatGPT because it's easier/simpler. I'm pretty sure an average person has no idea that chat.com will redirect you to chatgpt.com (or what a redirect is for that matter). It's similar to how people were calling the COVID-19 pandemic or the virus itself "covid".
rpozarickij··on Meta reaches $17B settlement over social media harms to children
The Unhook extension on Firefox does a very good job of hiding various parts of YouTube (including Shorts) that you don't want to see/access.

I use the YouTube app very rarely, but out of curiosity I went to iOS YouTube app settings, and I wasn't expecting this, but apparently in Time Management you can set Short Feed limit to 0 and this hid shorts completely from my YouTube app home feed and I can't scroll to the next Short when I open one.

rpozarickij··on After wearing the Pebble Time 2 for two weeks, I'll never buy another smartwatch
Before owning a Garmin watch (Epix Pro Gen 2 in my case) I had no idea just how useful always having a flashlight* with you is. I'd put this feature near all the health/digital features in terms of usefulness. I have it set to red light mode by default and double-pressing the light button gives me instant and unobtrusive night vision. I have also turned on the Red Shift mode for the display which makes the watch itself much more pleasant to use.

* not all Garmin watches have it AFAIK

According to Wikipedia [0] the headquarters of IERS (International Earth Rotation and Reference Systems Service) is in Frankfurt, Germany (contact information on their website [1] has an address in Frankfurt too). The web server hosting the linked file also contains German text in its error page:

rpozarickij··on Learn Vim motions with an ice-cream van
There's also Homerow [0] that adds Vimium-like features OS-wide on macOS. It does have some rough edges but overall I've been very happy with it. It usually works well even on apps that don't have proper keyboard navigation implemented and also handles situations with many clickable elements very well (e.g. IntelliJ).

rpozarickij··on Slow breathing modulates brain function and risk behavior
There's also a level above that, where you're aware of what is aware. I find this mental state to be even more calming/grounding than being aware of breathing but I'm not always able to shift myself into it. Being aware of breathing feels much easier/natural to me whenever I'm able to remind myself of it, which already provides quite a noticeable effect on how I'm feeling and reacting to whatever is happening in that moment.

Additionally, there's a practice called "walking meditation" [0] that can also be useful to practice this area of skills.

rpozarickij··on Creatine raises brain energy levels and slows cognitive decline: study
While this is true, but to my understanding this applies to women as well. Even one of these things has lots of benefits, but both are even better.
rpozarickij··on Creatine raises brain energy levels and slows cognitive decline: study
Magnesium Taurate is the form of magnesium I settled on. I take 1500mg of it (300mg elemental Mg) every evening before sleep, but I feel that even half of this dose has a noticeable effect on my sleep.

Magnesium Glycinate was destroying my sleep even when I took it in the afternoon. I'd wake up after 4-5h of sleep and would feel completely alert as if it was midday and then tiredness would slowly ascend on me over the next few hours but I'd still be unable to fall asleep.

rpozarickij··on Naphtha shortages in Japan
> If simpler packaging lowers costs and sales stay the same

In reality packaging is a very big part of marketing. People are drawn by vivid and bright colors, which is especially relevant in the modern world where unfortunately so many of us are living in a permanent hyper-stimulated state. It's hard to ignore well-designed packaging with tastefully chosen colors even if you're someone who is mindful about their eating/consumption choices and you know that what's inside that packaging is totally different from what you see from the outside.

rpozarickij··on Ferrari Luce
I wonder whether the mere-exposure effect [0] could also be at play here.

For me, the first reaction to the Ferrari Luce was utter shock, but after looking at it again several hours later I'm starting to see some of its exterior elements differently (although my brain finds it hard to call the car "beautiful" in the same way as some of the other recent Ferrari models).

It looks like a decision was made to depart from the "modern"-looking Ferraris, but the direction of that departure seems to be very different from what the competitors are doing and what the general public is looking for visually in such a car (but it's worth keeping in mind that members of the general public aren't really customers of this car).

rpozarickij··on SANA-WM, a 2.6B open-source world model for 1-minute 720p video
When I installed very high quality (CRI 98, R9 94, virtually flicker free) light bulbs to one of my apartment rooms I had headaches and felt occasional confusion for about a week while being in that room, so I had to slowly increase the amount of time the light bulbs were turned on for. To my understanding my brain was very used to the way objects and lighting looked in that particular room so it needed to rewire some knowledge given that I've spent many thousands of hours in that room with previous light bulbs.

I'm curious if a younger me would have adapted much faster.

rpozarickij··on Virtual violin produces realistic sounds
I've played other instruments (not very professionally) for 10y when I was much younger but was often surrounded by sounds of violins and these don't sound realistic at all.

My main instrument was the saxophone and whenever I hear AI/artificial saxophone somewhere I can notice it right away, but I'm very curious if I've ever been a victim of the toupee fallacy.

I wonder whether there's a good test/game where you have to guess whether a given sound of a musical instrument is real or not.

rpozarickij··on Claude Code is locking people out for hours
It's also worth keeping in mind that Anthropic's compute needs are nothing like those of a company like Shopify or Adobe, so revenue might not paint accurately enough the picture of what they're dealing with right now.

rpozarickij··on AirPods Max 2
I'm curious whether Apple has addressed the tinnitus issue of its ANC technology (or some part of it).

I couldn't use neither AirPods Max nor AirPods Pro (1st generation) because they were making my tinnitus noticeably worse.

I have no such issues whatsoever with my Sony WH-1000XM4 and a few other ANC headphones I've used.

rpozarickij··on Tinnitus Is Connected to Sleep
In addition to uBlock Origin I'm also using AdGuard as my home WiFi DNS server and I'm seeing zero ads and no cookie notices in the linked article. For cookies I'm using uBlock Origin's Filter lists which are available in the extension settings.
rpozarickij··on Show HN: Mines.fyi – all the mines in the US in a leaflet visualization
I'm pretty sure for me "mining.fyi" wouldn't have created any associations with landmines (although "mines.fyi" does seem to match the contents of the website closer).

It'd be really interesting to see A/B testing results about what most people associate the word "mines" with (I wouldn't be surprised if that would be landmines in this day and age).

rpozarickij··on I found a useful Git one liner buried in leaked CIA developer docs
This isn't exactly the same but I've been using git-recent [0] (with `gr` alias) for many years. It sorts branches based on checkout order (which is what I usually need when switching between branches) and allows to easily choose a branch to checkout to.

rpozarickij··on Pink noise reduces REM sleep and may harm sleep quality
I use the Background Sounds feature (in Accessibility settings) on iOS with a Bluetooth speaker every night while I sleep. It's quite battery-friendly and has several sound options alongside dedicated volume control with which you can set background sound volume independently of the main volume. It's also possible to add a shortcut button to this feature in the Control Center (the screen that's shown when you pull down from the top of the screen).

This makes occasional outside/neighbour noises much less noticeable, although I do keep earplugs near my bed just in case (not great for my tinnitus, but still usually better than without them if they're needed).

rpozarickij··on Two days of oatmeal reduce cholesterol level
Limiting animal fats (which are mostly saturated fats) has a very noticeable and measurable effect on how I'm feeling and doing overall. Primarily using olive/avocado oil and nuts/seeds as my fat sources significantly improved my energy levels, mental clarity, sleep, and stress/HRV (as measured by my Garmin watch). I've noticed this so many times that I don't think this is a placebo. I haven't checked any specific blood markers that might be affected by dietary fats though.

Saturated fats _are_ essential for humans but you should be getting enough of them from non-animal sources.

YMMV
