dirtyaura··on Marc Andreessen Says One Job Is Mostly Safe from AI: Venture Capitalist
It is same time hilarious take as described in the article but also a weird take for smart man in many ways: surely entrepreneurship itself will also change if AI did replace most of the human jobs. Why would those psychological factors matter as much as they did?
dirtyaura··on A look at the creative process behind Bluey and Cocomelon (2024)
Moomins - the 90s version especially. Most of the episodes are suitable for toddlers and at least our kids have been enjoying it.
dirtyaura··on Take the pedals off the bike
Same with my daughter. We tried with balance bike, but she didn't adopt it and didn't find it fun to try. We went to training wheels and she was immediately motivated. And at the same time, I've heard success stories with balance bikes from my friends.

Kids are different, try out different things.

dirtyaura··on The EV Transition Is Harder Than Anyone Thinks
Can you list examples of those countries?

I haven’t analyzed the whole world, but in the developed parts of Europe, EV fuel costs are clearly cheaper than ICE

dirtyaura··on Ways to ship software
An excellent piece. I’m especially interested to hear stories from the fellow HNers about the last point Jocelyn mentions: how to build 2 shipping cultures inside one company, when your business requires it (for example: two-sided marketplaces with different apps for consumer and businesses).

In our case, we have this situation with SW vs HW shipping culture. On the SW side, we focus on continuously developing features and have deliberately emphasized productivity over schedule-predictability, while on the HW side they naturally are focused more on schedule-predictability due to complex dependencies.

Now, this dichotomy has created an interesting discussions inside the company on the right way to ship products and projects, and to me, arguments mainly come from the fact that people come from the different shipping culture and have hard time to see the benefits and requirements of the other culture.

dirtyaura··on Nuclear power looks to regain its footing 10 years after Fukushima
There are several countries that have reaped benefits of nuclear power for decades. In Nordics, both Sweden and Finland has over 30% of electricity generated by nuclear. In Eastern Europe there are also several countries (Ukraina, Hungary, Slovenia, Slovakia, Czech R) with a big chunk of their electricity generated by nuclear.
dirtyaura··on Ultra Safe Nuclear
This argument doesn’t hold. There are several countries such as Finland that have operated nuclear power plants for decades and do not have ambitions for nuclear bombs.

This is incorrect, the Oura ring 2 has been mostly designed by in-house team, not Haltian. They have been involved in the process though.

dirtyaura··on Cut global emissions by 7.6% per year for next decade to meet 1.5°C Paris target
Storage and grid stability problems are still largely unsolved. When wind and solar starts to be 30-50% of the capacity, this problems will get serious. If you factor the cost of storage solutions, the cost of wind and solar against nuclear is not that lucrative any more
dirtyaura··on What are some alternatives to Fitbit products?
The Oura ring especially for 2. and 5. https://ouraring.com

Oura focuses on the night-time measurements, such as HR, HRV, temperature and sleep quality. It also tracks your daily activity and inactivity level. It summarizes all this to your ”readiness”.

Especially temperature is a game changer that no other popular wearable has.

dirtyaura··on The Epstein scandal at MIT shows the moral bankruptcy of techno elites
Hiding the origin of money in case like Epstein is clearly wrong. It prevents the bright people to make informed choices - based on their moral standards, not yours - where to work at. There are plenty of scientists who don’t want their work to be funded by that kind of money.

Oura (ouraring.com) | Backend (Python) Developer | Helsinki, Finland | Onsite

https://ouraring.com/careers/

Oura is a fast-growing consumer company that helps people track and improve their sleep using the Oura ring. We are looking for a Python backend developer to strengthen our team.

Oura offers intellectually and technically interesting challenges that differ from typical web app scaling problems. The Oura ring’s sensors have tracked millions of nights of biodata and helped people in over 70 countries to improve their sleep and recovery – and this is only the beginning. Oura’s mission is to empower people to own their potential, giving them the insight and tools needed to be in control of their life.

Oura has solid financial backing and a steady revenue stream. We are now expanding our core cloud development team to better support our rapidly growing customer base.

Our office is located in the center of Helsinki – Kaisaniemi – which is easily reached by public transportation.

As a fast-moving startup, we focus on delivering customer value and being productive. As such, we leverage AWS managed services whenever possible.

dirtyaura··on Non-English-based programming languages
This is absolutely amusing. Seems that the creator of the Tampio language has created several esoteric languages, one of them being domain specific language Retki for writing interactive fiction. It is also based on Finnish language. https://www.kaivos.org/projektit.html
dirtyaura··on Evernote Blows Up the ‘Fail Fast’ Gospel
If a personal productivity tool provides real value and costs $60 dollars per year, it is a no-brainer buy even from personal budget. Most higher income information workers earn that in an hour or two.
dirtyaura··on Evernote Blows Up the ‘Fail Fast’ Gospel
Why wouldn’t ”note taking on steroids” be worth $1B? It is useful for any information work, and most of the higher income jobs are essentially or at least partly information work.

And if they are currently making close to $100M in annual revenues, then $1B valuation doesn’t seem far off.

Lock-in effect is quite substantial after you have a couple of years of tagged information.

As a user, I just wish they would have a smoother implementation of their current product-offering.

dirtyaura··on Boléro: Sergiu Celibidache (1971) [video]
I don't know why this is in HN, but thanks for posting this. I have always loved Bolero for its hypnotic transcendental feeling, that can be found in music of Terry Riley, Arvo Pärt and electronic music. I started to reading about Sergiu Celibidache and he seems a very interesting composer. A teaser from Wikipedia:

"Celibidache frequently refused to release his performances on commercial recordings during his lifetime, claiming that a listener could not obtain a "transcendental experience" outside the concert hall. Many of the recordings of his performances were released posthumously. He has nonetheless earned international acclaim for celebrated interpretations of the classical music repertoire and was known for a spirited performance style informed by his study and experiences in Zen Buddhism. He is regarded as one of the greatest conductors of the 20th century."
