Nice! I am partial to this retirement calculator: https://networthify.com/calculator/earlyretirement

But then I'm biased because I created it.

Thanks! Thats exactly what I was aiming for. I'm glad that came across. I was thinking the same thing although I didn't actually discover https://learnxinyminutes.com/docs/perl/ until after I had written Minimum Viable Perl.

You rock.

You have high fidelity repls for python and ruby. The Perl hi fi repl is called Reply (https://metacpan.org/pod/Reply). If you are interested check out the plugins -- especially for Term::ReadLine::Gnu. If you have questions, let me know.

Most languages probably don't have the ability to download dependencies from the internet on the fly. That might be a nice feature to have.

Great response. I'll pile on:

Many people retire at 50 or 60 and don't die until 80 or 90 these days. Thats 20 - 30 years of living often while dealing with very high medical bills and health problems which can make work impossible. Everyone (not just programmers) should realize that their retirement situation is similar to professional athletes.

Programming is a hot field now and won't be in 20 years. Everyone in every country in the world is learning to program. Thanks to the internet its going to be a global employment market. Competition is going to go up. Salaries are going to go down.

Movies and popular culture say you have to enjoy your youth. I can sympathize with that, but as much as it sucks to work hard during your twenties, it would suck a lot more to work hard during your 60s or 70s when you are less healthy. Don't procrastinate.

If you save 60% of your salary you can retire in 13 years. If you save 80% of your salary you can retire in 6 years.

I built a tool that does this math for you: http://networthify.com/calculator/earlyretirement

I struggle with this all the time. Data driven tests are awesome because you write so little code. But the code is often abstract and the data is long and hard to read.

I have never been a big fan of Cucumber either and I'm not convinced its more readable -- isn't it just more verbose? Interesting point about it being language agnostic though.

I guess I don't have a better solution to contribute. Just wanted to say yeah I have that problem too.

Thanks! I have never heard of these. Here is the complete list of Amazon's leadership principles: http://www.amazon.com/Values-Careers-Homepage/b?ie=UTF8&node...

Excellent app! This is the writing style my high school composition teacher drilled into my head. Everything I write now is influenced by her.

I also try to write my code using this style. In fact, code and documentation and email should be:

1. As short as possible: Less words mean less stuff to maintain and comprehend.

2. Simple: The goal in business is to communicate well. Not to impress. And if I haven't communicated clearly, maintaining that code is going to be hard for the next person who has to read it.

HN navel gazing aside -- I think this is really good advice. Rather than trying to impress your coworkers -- try to impress your users.

I think the challenge in many companies is getting enough access to your users that you can tell if they are impressed or not.

I'm going to try to think this way more.

I'd love to chat with you about this stuff on email if you are interested. My email address is in my HN profile. Thanks for the comments!

Thats a great point. I do mention it in my blog post on withdrawal rates! (http://blog.networthify.com/withdrawal-rates/)

Its worth nothing that you could end up with an ever widening gap, but you could also end up with an ever growing surplus if your early years get > 4% return.

I don't think any calculators really deal with this other than http://www.firecalc.com/ (which has a terrible ui -- look for the big red 'Start Here' text and then click the 'Submit' button). Building a user friendly firecalc clone has been on my todo list for while. I'm not sure where they got their data.

With regards to my other calculators on Networthify, I'm not sure how to create a usable ui that reflects this reality.

Also there are at least 2 other big unknowns -- taxes and inflation. So when I'm calculating how much money future-you will have I'm not too worried about ROI. I agree that people need to understand these calculators are just educated guesses. Still -- you do the best you can with the information available. Its better than closing your eyes and not even examining the possibilities. At least you can calculate some worst case and best case scenarios.

-- UPDATE

Oh hey, do you mean there is some sort of formula for expected annualized return?

Yeah $2 can add up. I like to read the early retirement blogs and would like to somehow someday be financially independent.

The way I like to think about it is to figure out how big of a nest egg do I need to earn enough of a return to cover that expense in retirement. For example, I would need an investment of $18,000 which earns 4% avg annual interest to cover my $2 daily coffee expense forever.

Its fun to think of all your expenses this way and as you build your investments you can see how much of your lifestyle is paid off forever!

I built a little calculator to do this math for me: http://networthify.com/calculator/recurring-charges

The title is better than the article.

Humans and robots are merging more than they are competing. Its a symbiotic relationship.

Agreed. Fugitive rocks. I use it more than I do the command line. However I've never been happy with its ability to review history.

tig is one way to cover that gap, but I wanted to do my git log viewing in vim so I can more easily cut and paste. I wrote this git log viewer (vim plugin) to cover that gap:

https://github.com/kablamo/vim-git-log

You could get a job in a foreign country. Depends on your situation but for many programmers this is not a difficult option these days. Then you could make money while traveling instead of spending money.

I built http://iijo.org. Its free and does Chinese flashcards and uses spaced repetition. You can build vocab lists from a built in dictionary. You can also directly search the dictionary: http://iijo.org/dictionary.

And the code is on github: https://github.com/kablamo/iijo.org

Non code parts of Perl including the perlfaq and some of the Perl community infrastructure are available on github here for people wanting to do drive by fixes:

Probably this should be more widely known. Unfortunately I think some of these repos are old forked copies? For example the PAUSE and YAPC repos. I'm not sure why that is. Its not clearly documented how it all works exactly.

My side project is based on this article. I was intrigued by the graph in this post and so I created an interactive chart to explore it. The calculator will tell you how quickly you can retire and what your savings rate needs to be.

Sorry but I've become a bit of a personal finance nerd recently. :) Here is the story on withdrawal rates:

The 4% number comes from a study that discovered that a portfolio with a constant 4% rate would survive any period in US stock market history -- even the Great Depression. But past performance doesn't guarantee the future performance. Try to do this with European markets and there are periods where a nest egg won't survive a 0% withdrawal rate. But yeah 4% is the guess people use when planning retirement.

Thats fine, but in real life you have to be flexible as you approach retirement and keep an eye on the math. The first 10 years of retirement are the critical ones. After that you hopefully built up a buffer and don't have to worry due to the nature of compound interest.

Winning the startup lottery would be awesome but probably requires some amount of luck. If you save (for example) 80% of your savings you can retire after 5 years and never have to work again. Its not for everyone but you might be surprised at how little suffering is required. There is a community of "early retirement extremists".

Oh. Hey. This is my site. I will fix that.

The interesting part to me is they are selling their service via mashape.com which is new to me. Its a neat marketplace for "cloud APIs". Some of the APIs are free or freemium. Here is a list of the most popular APIs:

  - Facial recognition API
  - Yahoo weather API
  - Multilingual sentiment analysis of text
  - IP utils
  - Barcode / QR code generator
  - DuckDuckGo Zero-click Info
  - Bitly url shortner
  - Whois

I'm a Perl guy and don't know Ruby. Jekyll is excellent, but I ended up going with http://ruhoh.com which is based on (forked from?) Jekyll. That worked great. Ruhoh is sort of language agnostic. My biggest hurdle was grokking Mustache.

On a side note, I also had a problem with the RSS generator. I managed to submit a patch for my problem. I was pleased to discover Ruby is so Perlish! I guess thats obvious given that a lot of Ruby is inspired by Perl. I suspect switching back and forth between the two would not be hard.

> Attach to any running process and analyze away.

Interesting. It never occurred to me to want this. What sort of use case is this for? It seems Perl is capable of something similar:

    use Enbugger::OnError 'USR1';

learn more here: https://metacpan.org/module/JJORE/Enbugger-2.013/lib/Enbugge...

The stats in the link are interesting. I recently discovered the Code::Statistics module (https://metacpan.org/module/Code::Statistics). It tells you the cyclomatic complexity of your code which wikipedia tells me is basically the number of possible paths through your code.

It might be fun to see that run against the Perl core.

I also like looking at the number of lines of code. If your features go up while complexity and lines of code go down -- that could be a good sign.

The calculator assumes you never want to draw down your nest egg -- ie your savings will only grow larger. It also assumes you will spend the same amount in retirement that you spend now. Your rate of withdrawal is pretty much a wild guess as it depends on your rate of return, taxes in the future and inflation in the future. Historically 4% has been a good bet. See this article for a summary of this topic:

http://www.mrmoneymustache.com/2012/05/29/how-much-do-i-need...

and this article for more in depth writing:

http://financialmentor.com/free-articles/retirement-planning...

Thanks! I like the idea of a chart for annual rates of return.

The withdrawal rate is a little tricky. The withdrawal rate is the percentage of your retirement nest egg you will be spending each year. If you decrease your withdrawal rate you will need to save a bigger lump sum to compensate for the smaller amount of income you are generating. Therefore it will take longer for you to retire.

I'd love to hear any ideas/reviews. I was inspired to create this calculator after reading this Mr Money Mustache article:

http://www.mrmoneymustache.com/2012/01/13/the-shockingly-sim...

If you are interested in the math behind the calculator see my blog post about it here:

This is very cool. How do you plan to make money?
