CSS tips

Been back in CSS today. Here are some things I learnt today.

1) text-transform will allow you to transform the text to uppercase, lowercase or capitalize i.e.

h1 {
text-transform: uppercase;
}

This is a handy alternative to typing everything out in upper case (which is bad because the designer may change his mind to switch away from all caps at some stage).

2) If you are going to use jQuery to show/hide a table, wrap it in a div and toggle that instead. This is because show/hide/toggle in jQuery changes something from display:none to display:block. A table's display is inline-table by default and setting it to block will lead to some unexpected results.

3) If you have to write CSS (or anything) for IE only, you can use conditional comments
<!--[if IE]>
Special instructions for IE here
<![endif]-->
It's best not to use special CSS code for IE at all, but in some cases it's unavoidable.

4) You can modify the sliding doors technique by using a single image (instead of 2 images). The advantage to using a single image is fewer graphics to download (as they are cached).

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.
