plahteenlahti··on Ask HN: Share your personal website

Mostly mobile and web development, emphasis on monetization, and some cognitive science stuff (before I became a developer)

plahteenlahti··on Launch HN: FlutterFlow (YC W21) – Build Apps Visually
Looks great! Reminds me very much of AppGyver, which is a tool I've been using in few client projects. It uses react native under the hood, allowing for example creating logic using either the node-based logic builder or plain JavaScript. Interested to hear where do you see your advantage over AppGyver and similar tools?

One pain point of mine in visual app builders is the not being able to search the "code", for example when I've built a logic for fetching and mutating data in one view and now need to change it but can't remember where it is. Have you come across this problem and have you already solved it/have a plan for solving it?

The new remote is a welcome change. If it's backwards compatible I might end up buying just to replace the current one which is very inaccurate for navigating.
plahteenlahti··on Show HN: Netli.fyi – React Native app for managing Netlify sites
I made this app originally half a year ago because I use Netlify for a lot of sites and needed a quick way to check deployment information and form submissions. Finally two weeks ago I decided to see if anyone else would have any use for it and fixed a few bugs, bought a domain and setup testflight beta group, which ended up getting close to 200 users and a lot of feedback.

It's built with React Native. Works for on both iOS and Android, and is free to use through the open beta programs. Let me know what you think and what features you might possibly want to see.

plahteenlahti··on Show HN: Site with information about stocks
Hey this is actually something I’ve been looking for! It’s simple and fast without the extra stuff you often find on sites proving the same stock search functionality. I also like the ability so explore by country. What are you using as the data source? Would it be possible to bring figures such as P/e to the site as well?
plahteenlahti··on Ask HN: What interesting problems are you working on?
Oura seems to be the most accurate at the moment, but only by a small margin, and that is mostly because it's the only one that uses also temperature to measure sleep (in addition to heartbeat and movement).

Detecting when person is asleep has become quite good, but there's still a lot of work to do in also detecting sleep stages. I would not trust any wearables deep sleep readings too much.

plahteenlahti··on Ask HN: What interesting problems are you working on?
I'm trying to get people to sleep better by providing them relevant sleep coaching by combing their sleep tracker’s data with CBT-I derived sleep coaching program. Been working on this project for a year now, and it’s finally starting to take the shape I wanted it to have.

Been a really tough journey. I’m was the only coder and designer in the project for the longest time, and my development skills weren’t really that good when I started building this.

Maybe posting this will give that much-needed motivation to finish up on the two recent blog posts I've been postponing for over a month now.

plahteenlahti··on Ask HN: Books you plan to read in 2020?
Currently, my list of to-reads looks like this:

Non-fiction:

The Upstarts: How Uber, Airbnb, and the Killer Companies of the New Silicon Valley Are Changing the World

Invisible Women: Data Bias in a World Designed for Men Hacking Darwin: Genetic Engineering and the Future of Humanity

Bad Science

I'm Afraid Debbie From Marketing Has Left for the Day: How to Use Behavioural Design to Create Change in the Real World

Fiction:

This Is How You Lose the Time War

Catch-22

The Wanderers

I could definitely use some more fiction. Any suggestions?

plahteenlahti··on Launch HN: Aura Vision (YC W19) – Google Analytics for Physical Stores
Your explanation on how you plan to keep the data anonymised sounds good. I also love that you’re using existing cameras, I recently observed as a large it-consultancy piloted their multi-camera solution with a large Finnish grocery store chain and got rather poor results, mainly due to cost and amount work being too high when compared to the results.

This also instantly reminded me of the time I used to work in large thrift shop. Everyday the owner would count the daily visitors and compare it and the daily sales number to factors such as the amount of tables, changes in floor plans, amount of new items etc. He would have loved something like this.

Good luck with your product!

plahteenlahti··on Things I Don’t Know as of 2018
According to his tweet [1], there is a separate hiring track for front end engineers that does not include that much algorithmic knowledge. I was surprised too.

plahteenlahti··on Ask HN: Great books you read in 2018?
Really enjoyed Lost and Founder by Rand Fishkin https://www.goodreads.com/book/show/35957156

It’s an honest look at the life of a startup founder, but without all that self-congratulatory stuff and bragging you often find in these books. I would say it is a definite read for anyone thinking about joining the crazy world of startups.

plahteenlahti··on Ask HN: Recommended way to develop Android apps in 2018?
Flutter is worth looking into, and is currently being pushed quite a lot by Google as well. Key benefit over Android development with Kotlin or Java is the possibility using the same codebase for both iOS and android apps.

I’ve tried Flutter a little and personally still favour React native over it, mostly because of my web design and development background. However a lot of my colleagues and friends are leaning heavily towards Flutter in their projects because of its better developer experience.

plahteenlahti··on Ask HN: What new business you did you start in 2018?
I started a health tech startup, and our first product is a sleep coaching app, which combines user’s sleep data with sleep coaching protocol to train people to sleep better and manage their circadian rhythm.

Was able to get a paid pilot with a life insurance company by showing them the prototype and also currently negotiating with two large hospital chains to offer the app for their customer as work wellbeing solution.

Interested to hear what flexbox features were unsupported? I’ve been in a same kind of situation but was able to support everything on “IE version” of the app by using flexbox.
plahteenlahti··on Ask HN: Did you delete your Facebook account in 2018?
Deleted my account permanently two months ago. In the beginning it was interesting too see how it had become a habit to write the url almost without thinking, and for three weeks I found myself opening a new tab and writing the Facebook.com address every time my mind started wandering. Also deleted my Instagram account at the same time and currently in the process of deleting WhatsApp as well, as soon as some projects depending on it as the communication platform conclude.

Can’t say I missed it. The things I’ve lost in terms of communication power are far outweighed by the positive effect it has had on my wellbeing and time management. Other than that the effect has been relatively small on my life.

At the time of deletion I had around 700 “friends”, most of which I hadn’t seen in years and many of which I had had no connection after becoming friends on Facebook. Now two months after is feels weird to have used this service daily, when in reality it worked mostly as an address book than a communication platform.

Another thing I noticed was how invested I had become in other people’s lives by mostly just consuming their status updates, stories and pictures. This combined with lack of updates from my side had really distorted my relationship with people, and had me feel more connected to people than I really was. It has wonderful to notice how much more interesting and easier it has become to converse with people when you don’t know what they’ve been up to recently

Both actually work in improving the quality of your sleep and whether you should exercise in the morning or in the evening depends on your chronotype. However if you decide to exercise in the evening you should aim to be done with it at least 2 hours before your normal bedtime.
plahteenlahti··on Ask HN: 2018 Summer Reading List?
I think this depends how you value your time, and how you feel about reading. I personally feel that the point of reading is not simply about understanding the fundamental ideas those books are about. More important is to do something you enjoy, and if you don't enjoy reading that much, going with the more efficient way is most likely the better way to go.
