Global Warming is a Year 2000 problem

Global Warming is a Year 2000 problem.

What I mean is not that Global Warming has been solved (far from the case) nor that it is a problem that we could only have solved 15 years ago (though that might be closer to the truth).

What I mean is that if we solve Global Warming, then people will think it was a hoax (or something we should not have worried about).

Think back to the glory days of the 1990s. Media was full of stories about how all the world's computer systems were going to fail because programmers tried to save space on their systems by dropping the first 2 digits off the year field. Power stations and ATMs would stop working. Global financial crises would ensue (well, that did happen, but for other reasons...). Basically we were going back into the stone age unless we chucked large amounts of money at software developers to fix our computer systems and by and large that did happen.

After we partied like it was 1999, apparently nothing happened. I am sure a couple of systems failed, but nothing major. We were all still alive and we still had electricity and we could still get money out of ATMs.

Post 2000, everyone now thinks the whole thing was just a bunch of hooey.

But maybe we did avert major disaster by all our hard work. We will never really know.

I hope to an extent the same thing does happen with Global Warming. There are differences of course. We have not got a set date where the planet will be uninhabitable. A date when we can look back and laugh at ourselves for being so silly.

Instead, we will look back at ourselves in shame for being so oblivious (and remember what things used to be like).

There's probably not much we can do on an individual level. We will need to elect people who are aware of the problem and reach consensus (easier said than done).

Let's just hope that in 7984 years we have a Year 10,000 problem to deal with ("Why on earth did they think they could save space by only allocating 4 digits to a year?").

Master of my domain

Hi All, I just got myself a new domain ( http://www.skuunk.com ). The reason is that Blogspot.com is offering cheap domain via GoDaddy.com and I thought after having this nickname for nigh on 10 years it was time to buy the domain before someone else did (also I read somewhere that using blogspot.com in your domain is the equivalent of an aol.com or hotmail.com email address...shudder...). Of course I forgot that I would have to re-register my blog everywhere (which is taking ages) not to mention set up all my stats stuff again. *sigh*. It's a blogger's life... In any case, don't forget to bookmark the new address and to vote me up on Technorati !

Elixir - destructuring, function overloading and pattern matching

Why am I covering 3 Elixir topics at once? Well, perhaps it is to show you how the three are used together. Individually, any of these 3 are interesting, but combined, they provide you with a means of essentially getting rid of conditionals and spaghetti logic. Consider the following function. def greet_beatle(person) do case person.first_name do "John" -> "Hello John." "Paul" -> "Good day Paul." "George" -> "Georgie boy, how you doing?" "Ringo" -> "What a drummer!" _-> "You are not a Beatle, #{person.first_name}" end end Yeah, it basically works, but there is a big old case statement in there. If you wanted to do something more as well depending on the person, you could easily end up with some spaghetti logic. Let's see how we can simplify this a little. def greet_beatle(%{first_name: first_name}) do case first_name d

Speeding up RSpec

So today I have been looking into getting our enormous battery of tests to run faster. I have yet to find anything that works for Cucumber, but I did find an interesting way to speed up RSpec which is detailed here. https://makandracards.com/makandra/950-speed-up-rspec-by-deferring-garbage-collection Basically, it seems that by not collecting garbage too frequently, you can make your tests run much faster (at the expense of memory management of course). We observed a 30% reduction in the time it takes to run an RSpec test suite. I did try to implement this on Cucumber, however because we need to store much more in memory to set up and tear down our objects, it meant that I kept running out of memory when I wasn't using the default Garbage Collection and the tests took even longer (so, buyer beware). I suppose if you had a small set of features though you might see some benefit.
