joeyrosztoczy1··on Ask HN: Why do software companies still insist on Estimation?
Estimates or scientifically wild ** guesses (SWAGs) can be an incredible feedback loop to peers, a team, or an organization.

For peers, far apart estimates might indicate differences in understanding of the problem/solution.

For a team, if they are wildly diverging or low-certainty it can indicate the right next step is experimentation or exploration, rather than committing on delivering something to production.

For an organization, they can provide a barometer for investment decisions, such as what the appetite to solve a given problem space is, or how to evaluate sunken costs.

I particularly like a progressive framework on estimates, i.e. 10% certainty when a project is just taking shape, 20% when scope gets tightened up, 50%+ after spikes / rfc drafting / design etc.

Often they are used for rote accountability, which can be detrimental and/or naive - they should be a stake in the ground to have discussions around risks, assumptions, and trade-offs!

joeyrosztoczy1··on Human speech may have a universal transmission rate: 39 bits per second
I feel like there's an important follow up study in how much humans can compress data with respect to those bits (cat -> large -> mane ~= lion).
joeyrosztoczy1··on Ask HN: What programming language should I learn next?
As a shameless plug, there are a lot of interesting perks for a generalist to using Elixir.

- Declarative + functional programming - Highly productive (great frameworks for embedded + web, developer ergonomics, etc) - Great exposure to Actor Model concurrency - Great generic performance (no stop the world gc, strong multicore use via Erlang scheduler + processes, and lots of optimizations based on vm immutability) - Lots and lots of exposure to systems stuff + strong devops tools (built for distribution*, Erlang runtime tools, observer, great logging and telemetry libraries, etc) - Lots of built in services/tools (can use ETS instead of redis for things like auth-checking throughput)

joeyrosztoczy1··on Give Me Back My Monolith
I absolutely love the way the Elixir/Erlang + OTP projects (even within frameworks like Phoenix) decouple code organization / administration from the software runtime itself.

You can have both ^^ (and every tradeoff whichever extreme you feel more comfortable veering towards).

joeyrosztoczy1··on Applied Monotonicity: A Brief History of CRDTs in Riak
Just have to plug the super-practical and awesome implementation of CRDT's in Elixir's Phoenix Framework used for pub_sub and in the Presence feature: https://github.com/phoenixframework/phoenix_pubsub/blob/mast...
joeyrosztoczy1··on Ask HN: How do you manage your mental health?
I've been working as a cofounder of a startup and fullstack engineer the last 4 years and have tried a lot of different things to manage mental health.

One important comment I want to make is that even well managed, life is a journey with peaks and valleys. Its part of being human to struggle with this (and occasionally conquer it).

Current habits / beliefs:

1. I've been practicing MBSR (mindfulness meditation) for 40 - 60 minutes 5 days a week for almost 2 years. I cannot stress how powerful I believe the impact of this practice has been for me, nor how challenging it is to develop this habit. The investment is absolutely worth it.

2. I cycle in and out of a ketogenic diet (2 - 3 months on , 2 -3 months off). I lost 40 pounds and got to a very healthy weight in the very first cycle, haven't needed to lose weight since but I believe the diet + the weight have a profound impact on my mood stability and self perception respectively.

3. Connect with people. I'm not sure if its because I enjoy writing software so much or have any natural tendencies toward introversion, but I've gone through periods where I don't do this and there's a good correlation there with my mental health. I'll prioritize activities with friends and families at the same "strict" level as meditation. They can add perspective and meaning to life in ways nothing else can.

Edit: Also in the worst of times I'll turn to "Feeling Good" by David Burns, and finally the plug for if things are really rough professional help is the way to go.

joeyrosztoczy1··on Ask HN: Are there any courses/course materials that teach oop concepts well?
This is an all time favorite: Sandi Metz' Practical Object Oriented Design https://www.amazon.com/gp/product/0321721330/ref=as_li_tl?ie...

It takes the cognitive overhead off of the programming language completely and focus on design principles in a really modern learning style.
