Why not just milk it until the money train dries up or you are rolling in cash? Just because one or more companies offer the same product doesn't mean you're going to squashed. What will tank your business is losing focus & giving up before you needed to.

For me it's mostly about gow people use metaprogramming.

In Ruby, if I'm trying to find the source of a dynamically generated method in a dynamically generated class, that usually requires me to run add a debug statement, run the program, and see what's being passed. Even if I have a stacktrace, I often find it difficult to understand what the code is doing without running it.

I find Elixir code easier to read, and grepping my way through the code base is often enough. And to be fair, a debugger is often less than useful in macros involving AST & when dealing with a process that got a random message from who knows where.

And supposedly the virus can survive for an extremely long time in a dormant state. Could someone do a little bit of homework who died from smallpox, dig up their corpses, and find live samples that way?

Former insurance agent here.

You can think of insurance as a small & certain loss to hedge against a large & uncertain loss.

If stuff happens and you do need to cash in on that insurance policy, the payout should be thought of as saving your butt, also known as indemnification.

An airbag in your car is a form of insurance. You spent $X to protect yourself in a collision. The small & certain loss is spending the $X. Say you unexpectedly end up in a crash, but instead of dying, the airbag saves your life. It protected you from a death, the large & uncertain loss.

The idea of that buying an insurance is making a bet against yourself doesn't make sense to me. Insurance is more about making sure you don't lose. It's reducing risk, and a bet feels like taking on risk. The insurance company is the one making the bet, not the policy holder.

I was playing with a parser generator last summer, and it was immensely frustrating to bump into bugs it had & features it lacked. In the end, it was much easier easier to write the entire parser myself. So if I understand the point you're making, I agree that giving up control can suck!

I like to comment on how my next door neighbor's rent (here in SF) is under $300/month. He moved when in many years ago when the rent was $85/month. I pay just over $1600 for the same 250 square foot layout.

Here's how I go from dumb to less dumb:

- on Saturday, I wanted to learn how to write a Kubernetes configuration file from scratch, so I decided I'd deploy a static web page

- for the static web page, I decided it should return pictures of teapots w/ a 418 status code, and initially tried to return responses using netcat, which I got working on my local machine, but not in a container

- instead of using netcat, I decided that nginx is for people that don't like over-engineering their weekend hack projects, so clearly I needed to write my own web server and hacked out a janky Elixir server that serves up a poop emoji teapot image [1][2]

- then I started working on an overly over-engineered HTTP server, which so far only has date headers [3]

- then last night I randomly wondered how HTTP 2 works, looked for the RFC [4]

- then I remembered working on the date header, and I wondered how headers work in HTTP2, and I learned they use Huffman encoding, and so my next side tangent is to read up on Huffman encoding and add HTTP 2 header support to my HTTP server! [5]

TL;DR -- I made a poop joke and turned it into a learning opportunity

I'm imagining an overly academic interview question that goes something like this...

"It's been determined that our CS interviews are both random and unscientific, and we'd like to reverse that trend. To give us more control of the outcome, and to help us be more science-y, how would you design a random number generator which can be made deterministic by giving it a seed value? We need one for our hiring process."

This happened to me, too. I lived in a hotel, moved out, and was unable to forward my mail. My hotel room was considered to be a commercial address. I think this was in 2011.

>> You can't really build a product without talking with the customer or talking to other departments especially sales/marketing/customer service

A friend of mine works at a large enterprise company on a multimillion dollar software project. Their dev team has never spoken to a customer or product manager (there is a PM team, they've just never spoken with the devs). It also takes them a long time to ship software. It's very odd.

After having retired a couple of phones due to crappy battery life, my most recent phone purchase has a removable battery. I'll probably buy a new battery in ~4 months, when the phone is a year old. I'm happy I decided to follow that path, because I really like the phone (LG G5), and a replacement battery is less than $20 USD.

If net neutrality fails, would it makes sense aggressively pursue a legal effort to break up "big cable"? Back in the long distance/DSL days, the local telcos were forced into allowing alternate vendors to sell long distance & Internet service over the copper wire running to one's house. Can we bust up Comcast's strangehold on the Internet service available to my apartment by forcing them to allow any vendor to sell Internet over that single Comcast-owned coax line? They lobbied against neutrality, so take away their monopoly!

Speaking for myself, and I tend to make practical choices for what I understand now. At the moment, I am not using Rails in my day to day work, and this is largely based on my past experiences.

Pros:

- easy enough to find libraries for most things I wanna do

- community likes testing, as do I

- community seems to focus on business & web implementations, so good for those use cases

- lots of questions for which I want answers already answered

- package management

- deployment to PaaS/Herorku-ish platforms pretty easy for smaller teams

- here in San Francisco, there are lots of job opportunities for Rails developers

- I like Ruby, even though I am less excited about OOP these days

Cons:

- Rails is magical & opinionated, and that always annoys me

- Figuring out where some method is coming from in a Rails object is often a pain

- In Elixir I almost never need a debugger, but in Ruby I almost always do

- loading Rails apps can get really slow, and learning to wait for software to boot isn't a skill I like to develop

- I feel more pressure "to do it" right when the time "to do it right" simply doesn't exist for reasons, because trying to come back and refactor gnarly Ruby code is just harder than it is in a compiled language

- Ruby has to be installed on the system to which an app is deployed, and needing to think about how to pre-install Ruby or how long a Ruby install takes is a mild pain (stand alone Go binaries or Elixir releases are pretty sweet)
