tbrooks··on Ask HN: Team for Hire?
Chattanooga is a beautiful town. I almost moved their in January. The city has a lot to offer and it could be one of the next great tech hubs.

I decided not to move because I didn't think the local economy offers a lot of choice for software engineering jobs. When I visited people remarked, we've got VaynerMedia, we've got OpenTable, we've got CarbonFive, etc. etc.

This news sucks because I really want to see Chattanooga grow into a techhub, but it also confirms the suspicions I originally had. :/

tbrooks··on Crystal: Fast as C, Slick as Ruby
I don't have a CS background, so I can't speak much to the performance of Elixir and Crystal.

As someone who has made the transition from Ruby to Elixir, I'm really, really intrigued by Crystal.

Though, upon a cursory look into the Crystal docs and community, a couple things are clear...

Elixir killed it on all the things surrounding the language.

- docs

- testing

- Slack chan, IRC, mailing list

- package manager (Hex)

- build tool (Mix)

- web framework (plug & Phoenix)

- books from major publishers (manning, pragprog, etc.)

- ElixirConf

- ancillary teaching (ElixirSips, LearnElixir, Elixir Fountain, etc.)

While the language may not be as computationally performant as some of others mentioned, all the things above lower the barrier to entry for adoption and make Elixir a more attractive language than some of the counterparts. And it's amazing that a language this young has nailed it on these fronts.

Goes on to list strategy for only content writing system. No mentions of strategy on sales calls.

tbrooks··on Rails 5.0: Action Cable, API mode, and more
In all your replies, you haven't given concrete example of "I need arrays because tuples or lists can't do X".

Complaining in the abstract isn't helpful.

If Elixir had arrays, why would that be better than using other enumerables like lists or tuples?

tbrooks··on Investing Returns on the S&P500
It's unclear if the NYT accounts for dividend reinvestment.

Leaving out compounding interest could massively affect the returns shown in the chart.

Warren Buffett bet $1mm that S&P500 will outperform a hedge fund over a 10 year period.[1]

That's good enough for me, I'll follow the oracle.

tbrooks··on Ask HN: Profitable SaaS? How did you grow your business?
The main thing to consider is, as your customer acquistion scales, does your headcount/labor cost scale as well? If so, that should be a factor in your CAC calculation.

I don't think there's one canonical formula. But here are David Skok's thoughts:

"To compute the cost to acquire a customer, CAC, you would take your entire cost of sales and marketing over a given period, including salaries and other headcount related expenses, and divide it by the number of customers that you acquired in that period. (In pure web businesses where the headcount doesn’t need to grow as customer acquisition scales, it is also very useful to look customer acquisition costs without the headcount costs.)"

tbrooks··on Ask HN: Profitable SaaS? How did you grow your business?
David Oglivy (ad firm founder) has a great quote:

"If you want action don’t write. Go and tell the guy what you want."

tbrooks··on Ask HN: Profitable SaaS? How did you grow your business?
While this is true, if you're a one-person SaaS company you probably won't factor in your time as a cost. Sales (and some marketing) labor overhead should be factored as a direct cost to acquiring customers.

If you are "profitable" as a one-person company; make sure you are paying yourself a market-rate salary or are at least factoring in your time as a cost. If not, your SaaS acquistion metrics could be way off.

tbrooks··on Ask HN: Profitable SaaS? How did you grow your business?
Meat and potatoes selling.

1) Found a list of potential prospects

2) Called 30 prospects each day

3) Repeat steps 1-2 for 4 years

tbrooks··on What happened to Austin, Texas when Uber and Lyft left town
TL;DR

Reporter based in an area with great transportation choices (NYC) says, "Austin w/o Uber and Lyft ain't so bad. There are new alternatives."

tbrooks··on Replacing Celery with Elixir in a Python Project
OP mentioned that Elixir is better at concurrency and parallelism. Python is better at processing (more libraries/toolsets available).

As someone who wants to use Elixir more and see its community flourish, what libraries does Elixir need so this project could be done without Python?

I'm guessing some sort of Beautiful Soup or Nokogiri equivalent?

tbrooks··on What's coming in Elixir 1.3
I'm most excited about the Calendar datatypes.

There are 2-3 really good Elixir libraries around dates and times: calendar, goodtimes, etc.

Choice is great, but I really like a canonical library around something so core as time.

"Estate tax" is equally charged language, even if you aren't superrich and affluent.

OS processes !== BEAM process

He's referencing processes on the Erlang virtual machine, not OS processes. A BEAM process is much lighter weight.

tbrooks··on Mandrill’s Betrayal
I want to use AWS SES, but the lack of a dashboard (like Mandrill had) is a dealbreaker.

Quick strawpoll: are others in that boat too?
