I've decided to start writing a weekly post about the bugs I encounter, either in my personal code or at work.  Part of this is to just share tips/tricks... part of this is to share lols.

Most of my bugs will likely be in Scala code.  For those unfamiliar, Scala is a JVM-like language that adds in functional programming.  Basically, it's Java + Python.

---

This week's bug was a fun one.  So, we have this object (a singleton instance of a class), and it has a bunch of properties.  It also has an "All" property which is a set of them.  We'll say these properties represent languages:

object Languages {
 val All = Set(Java, Python, CPlusPlus)

 val Java = "java"
 val Python = "python"
 val CPlusPlus = "c++"
}

Can you spot the bug?  Yes, this does compile, so it's not that...

If I did this, you'd find it real quick:
scala> object Languages {
    | val All = Set(Java, Python, CPlusPlus)
    |
    | val Java = "java"
    | val Python = "python"
    | val CPlusPlus = "c++"
    | }
defined module Languages

scala> Languages.All
res0: scala.collection.immutable.Set[java.lang.String] = Set(null)
wtf.  Why is it a set of null?!  Well, as it turned out (after 4 hours of scouring through a ton of code built on top of this simple object), it's because Scala objects and classes evaluate those out of order... if I had made the vals below lazy (evaluated on call; not on defining the class) it'd have worked properly.  Sadly, that has a memory overhead.

The real solution is just to put All at the bottom of Languages:
object Languages {
  val Java = "java"
  val Python = "python"
  val CPlusPlus = "c++"

  val All = Set(Java, Python, CPlusPlus)
}

And boom.  It worked:
scala> object Languages {
    |   val Java = "java"
    |   val Python = "python"
    |   val CPlusPlus = "c++"
    |
    |   val All = Set(Java, Python, CPlusPlus)
    | }
defined module Languages

scala> Languages.All
res0: scala.collection.immutable.Set[java.lang.String] = Set(java, python, c++)

So, yeah, this was just an annoying bug that cost me almost an entire day.  Figured I'd share my annoyances.

I haven't seen Chozen's pilot yet.  I keep seeing ads for it on Spotify though.



btw, chances that they make a ton of NSA jokes this year?  I'm thinking it's high.

Little Talks - Of Monsters and Men

So, the episode was two nights ago. It wasn't as funny as I hoped, but it definitely set up the plot well for the rest of the season.

Thoughts? (You can use the spoiler tag to hide spoilers!)

People listen to my advice.

Sometimes... or, well, occasionally.

Consistency mainly.  That, and we're -already- editing the CSS file... might as well.  You can also then, in theory, expand it to be customizable using the Advanced CSS Editor by adding rules.  (Again, in theory. )

CTRL+F is a good improvement, for sure. In fact, I think they offer a shitty search field at the top of the box too.

Anyways to clarify... when you remove the CSS, you're telling it to just reset to an earlier rule... in this case, likely "width: auto;"

If we were to insert that rule at the end instead of deleting it earlier, it's easier to support future changes or removal of modifications.     

As long as they're all one sender, you're good.  Sadly, not easy to get one vendor.

Amazon will still send you multiple packages if they're different vendors.

Your lack of favorites disturbs me.

I'm sure many of you guys heard about the massive Adobe and Snapchat leaks (among others) recently.  It's a few weeks (or month for Adobe) old at this point, but it was a massive deal.

Well, one of the security bloggers I follow (Troy Hunt) decided to make a lookup service that let's you determine if your e-mail (or phone number) was leaked in any of the incidents.

It also lets you sign up for future notifications if you so choose.

(For the coders out there, he talks about the design of handling 1.5m records here and here (part 2). Pretty interesting stuff.)

Anyone want to try this as a weekend project with glue?

It's best to not ask questions sometimes.

It really makes me feel like your name should be twerk.
