IWantToRelocate

when I'm completely relaxed after a breathing workout, I sometimes dont "feel" the need of breathing, for long periods, is that normal?

Ask HN: For those who have ADHD – Inattentive Type – how do you overcome it?

A friend who is a psychologist came to warn me about this problem, which I possibly have and discovered only now in my 30s. Reading all over the web, I can say that I have ~ 100% of the symptoms since I was a child: inattentive, daydreamer, unable to follow instructions given, etc. All my teachers in my childhood always complained that I was never paying attention to classes. Unless it is...

yes, each user will have an user id (and also full name, phone and email)
thank you! We will use the data for customer segmentation purposes. For that, we will need to transform all the user's sources into a single entity for a given user, for example. And link that entity/user to another table, with their purchases so we can do the customer segmentation. I'm not sure about latency but honestly that's not really important at the moment, I just need to have a strategy to make an end-to-end solution for gathering the data, transform it and delivery a concise and coherent "user table" for the machine learning dude.

Ask HN: Best Practices for Creating a Golden Record or Single Source of Truth?

Hey HN.I'm facing this challenge at my job where I receive user's data from N sources and need to create a single source of truth (a table with single entities for each user).I'm looking for best practices, I don't even know how to start it.When I look for that on the web I find many random "tutorials" where it ends up trying to sell you a tool for that purpose. If anyone could point me in a...

Actually I don't feel it anymore since I started to practice deep breath before I close my eyes. It improved my sleep a lot.

You just described exactly what happens to me and that "sleep phobia", I read somewhere, is linked usually to people with anxiety/panic attack issues. Not sure if that's your case but 100% accurate in my case.

there's a guy in my building that 100% of the time he talks about the weather when we met in the elevator. its kinda funny that some people can't deal with silence for a few seconds
Re:Ask HN: Why is the Spotify UX so horrible? on Tuesday November 16, 2021 @09:47PM (#29248848)
Not sure about "all", but you have some ~free~ services on the web to convert playlists between deezer and spotify and vice-versa.
do you have any article pointing to that? i usually feel "powerful" for random activities after a 15min nap
Re:Fundamentals of Piano Practice on Sunday October 31, 2021 @12:13AM (#29054409)
started as an adult as well and couldnt stress this enough. anyone can play the piano with proper practice!
where I work at theres a beautiful, cool and collaborative office. friendly people overall. But I much prefer work at home or whatever I want. Just need a good ISP. If they ever tell us we need to go to the office in an arbitrary frequency, then im out.
Re:Show HN: Simple access to your music from the web on Monday October 18, 2021 @07:23PM (#28913113)
question: is it possible to cache the music locally somehow so you download/stream the track only once?
Re:Ask HN: Any Artists on HN? on Wednesday October 13, 2021 @01:47PM (#28855186)
being the type of person that need to focus on one task/life, i completely understand you! when I was commited to music production and paid the bills with it, I couldn't focus in any other thing/job. Now since the pandemics started, I had to focus in programming to pay the bills and had to quit music completely.
thats a great advice and makes total sense. thank you!

i make (electronic) music :)

thank you Paul for the references, will def take a look mainly in the early stopping problem.
thank you! on a quick look, that seems straight to the point, for someone who had calculus and linear algebra in 2006.
wolfram alpha told me its: cos(x) - xsin(x) lol kidding, i had calculus 15 years ago. so it sounds I should recap derivatives.
Thank you! appreciate your reply, honestly. i have an engineering degree but it has nothing to do with computers, so i kinda struggle sometimes. I basically want to get fluent with the metrics/performance when applying ML/NN, when to tweak what, how to improve some stuff, what algorithm works best for some of the problems, etc.
Well, not much. Data isn't the main product where I work for, so I end up just using python libraries for some mundane applications and small datasets (image classification and recommender systems). But I'm the "need to know from scratch" kinda person and I wonder if I should waste my time learning the math behind it or if its useless
