What happened with that guy? Did he ever come back?

  Rust is a unique language in that it deallocates memory on the heap
  without requiring the writer to call free,
  while at the same time having no need for a garbage collector.

Someone correct me if I'm wrong but surely this is not unique - don't Objective C and Swift have automatic reference counting which accomplishes much the same thing?

Agree with you 100%, and the ability to dynamically define methods is one of Ruby's great strengths.

However, metaprogramming is a power that should be used wisely. When implemented unnecessarily it reduces readability (and probably performance) for no real gain.

The devise source contains some great examples of metaprogramming used properly:

Just because you CAN do something doesn't mean you SHOULD.

Metaprogramming has a place in Ruby but for the examples in the article there are far more readable ways to implement it.

Readability > cleverness every single time.

Important to note that this isn't STATIC typing (which detects errors at compile-time), rather this is more like a validation library to make sure structures have certain properties at run-time.

Not saying it isn't useful, in fact I have a project in which this would be a very good fit and I might even implement it there.

Photos are everything man.

There are a tonne of average-to-poor looking girls on Tinder who have very good photos of themselves that paint them in a much more flattering light than they really deserve. Take a leaf out of their book.

Tinder is the most superficial distillation of dating out there, your entire judgement of the person is based on a few photos (and often just the first one).

You need 4 photos, show them in this order:

One full body shot of you with a clear image of your face, one of you topless (if you have the body for it), one of you looking cool with your friends, and one of you doing something you like, preferably some sort of adventurous hobby like climbing or diving

PAY TO GET PROFESSIONAL PHOTOS DONE. I can't emphasize this enough, more than anything else this will drastically improve your results.

The 'about me' field is almost irrelevant. Keep it to 3 sentences or less. When you get a match, push for a meetup at a bar (or your house if you feel bold) as soon as possible, preferably within 24 hours. Get their actual phone number within the first five messages. THE GIRL ALREADY LIKES YOU, there is no need to play silly games at this point.

I also use a Tinderbot to automatically like all the girls. I wrote my own version based off the work of somebody who reverse-engineered the API, my repo is here https://github.com/samphilipd/tinderzapper . When I feel like going on some dates, I just run that for a few days, unlike all the unattractive matches and push for meetups with the rest. It's a pure numbers game.

BELIEVE ME there are girls out there who will find you attractive and want to meet up with you, you simply have to sift through the junk to find them.

The above is pretty much exactly what I do. I'm only slightly above-average looking and very below-average height (5ft4). I do workout so I have a somewhat decent body. I've been on countless dates this year and got laid with 10-15 girls just through tinder.

Anyone can get a date on Tinder with professionally taken photos. In fact, most of the girls on there already know the importance of photos and are very skilled at showing photos that present them in the best possible light.

If you are writing Ruby you already decided you didn't care about speed.

Don't get me wrong, I think Ruby is a great language and I use it every day to get paid, but it is not a speed queen. Ruby's strengths lie in flexibility, fast iteration, readable code and permitting a functional style.

In most practical web applications the big bottlenecks will be either view rendering or database. Choosing to put any focus at all on performance of something like parallel vs serial assignment (unless you are doing something truly pathological) is a complete waste of time.

It will have no noticeable difference to the end user and distracts from the far more important job of making your code modular, extensible and readable.

If need your code to be fast and you are running Ruby, you already lost. Use Java or a compiled language instead.

Actually it does make a practical difference but I would argue in favor of the electric razor.

Ever wonder why it itches in those first couple of weeks if you decide to grow your beard out?

Look at that picture.

Shaving with a straight-blade razor basically leaves a bunch of tiny little hypodermic needles behind. When those suckers start growing out, they curl back into your face and start jabbing you, resulting in that annoying itching sensation.

If you want to grow your beard out, take my advice and make your last shave with an electric razor, it's a lot more comfortable.

Sounds like Rubocop for Ruby:

https://github.com/bbatsov/rubocop

Fast enough to integrate into a continuous integration build process and catches a lot of dumb mistakes/typos before deploying to production.

Ah I see the problem. Actually I used a Ruby console.

So what then is the CORRECT way of doing this comparison in C, avoiding potential overflow pitfalls?

WTF? The article states:

  x = 1987654321 and y = -1987654321? Then the difference between them is -319658654 (negative) which proves that x is less than y. That’s less than correct.

Which is completely 100% wrong. Surely the difference would be x - y i.e (1987654321 - (-1987654321)) = (1987654321 + 1987654321) = 3975308642.

Which is perfectly ok, because that's positive and so proves x is greater than y. So this comparison works just fine for negative integers...

At the risk of sounding callous, perhaps they are poor BECAUSE they are so indiscriminately generous.

Everyone is needy. Everyone always needs help. People have an infinite capacity to suck up your help and they will always need more.

Probably like many programmers, I love producing work for other people that makes them happy. There is nothing that delights me more than watching someone's face light up while using my software and saying "Oh, this is EXACTLY what I need!"

The problem is there are many people out there who will happily take your best work and pay little to nothing for it. I've learned this from bitter personal experience.

A truly selfless person would give their best work away forever for as little as they needed to survive. But this kind of generosity will leave you penniless and the kind of people that use your work for nothing will not thank you for it.

Your employer only pays you because he needs you. If you respond to neediness by giving, you lose your power and your ability to get paid for your work.

To retain wealth requires a kind of dulling of your own innate urge to help others. Because nobody else will stop you from giving and giving and giving until you are an exhausted shell with nothing to show for it.

I'm not saying this is the ideal way to behave, but we have to live in the reality that exists, not an imaginary idealized one.

This also depends on where you live, and your responsibilities. I lived for six months in western Australia working only 2-3 days a week as a bartender. Pay was about $160 per day, which works out to $1500-$2000 per month.

With no kids or dependents, this is more than enough to live on. I paid rent and food comfortably, had plenty of time to learn guitar, go outside and skateboard, meet girls and even had enough leftover to buy myself a new Macbook Pro. Plus it was a fun and social job.

You could live on even less if you were determined, for inspiration on frugal living read Walden by Henry David Thoreau.

Priorities change though - right now I suppose I 'work' about 10 hours a day, six days a week. This is because I decided I was going to learn to code and got motivated and driven to become good at it. Building a skill takes a lot of hours of focus and concentration but it's not 'work' if you get excited about it.

Forgive my ignorance... but why would anyone want their URL 'forgotten'. If they want to hide from the search engine, isn't that what robots.txt is for?

Well I don't tend to actually write much code out by hand. Usually I use a notebook for sketching out ideas, thoughts or todo lists.

For copying out code I use the same text editor that I program in.
