I must say it feels like it was ages ago when we started games, but we are almost at the finish line. I have no idea who is going to win the whole thing, but I have few candidates in mind that did wonderful job and quite frankly: I was learning from them, not other way around. Looks like I’m getting rusty with whole this “scripting” thing. 
I must say I was a little puzzled when reading description for this event. For me the main issue in this even is the lack of information about DHCP server. I assumed this is Windows 2012 (same as Hyper-V host), but I can’t find it anywhere in event description (I may be tired though and simply missed it). To be honest: we are not event told that DHCP server runs on Windows. 
It looks like I missed another deadline. Luckily, I’m not participating this year, so the only negative outcome of it is the fact that I will post my solution after most of you already seen entries done by others. I haven’t (I promise!) so you can expect many mistakes you’ve avoided by giving it second, third or fourth thought. I also had no chance to test it on some “real” material like some participants did (yes, I’ve seen your tweets and I’m sure you did it better, thank you for sharing! 
). Wonder how I could improve it… Surely – will find out soon. One note: I decided to focus on IPv4. Mainly because I started so late, and didn’t wanted to spent too much time on handling IPv6 addresses, that are less obvious to match with regular expression (IMO).
Active Directory is one of those things I just love to work with. That’s why I was looking forward to the entries in this particular event. I found out few things I was not aware of while reading some of the entries, but also seen some mistakes that I would like to highlight. As always: I will start with Beginner category “positives”, and move on until I get to “negatives” in Advanced category.
Time to summarize 3rd event of Scripting Games 2013. I must admin – I learn few new tricks while reading entries for this event. But I still see some things I really can’t stand. Especially in beginner category, where many people decided that putting everything in one line makes it “special”. It doesn’t. If you still think it does – read this article by Richard Siddaway. If you still think line break is cursed – read it again. Repeat. 
OK, I’ve seen your entries, and I must say – in general, I like what I saw. But it wouldn’t be helpful to tap you on the back and pretend everything is perfect, would it?
As previously, I will mention few pain points I’ve seen. I will also try to mention what I liked about entries. Let’s jump to beginner category first.
Now that event 2 is closed for new entries – time to let you guys know how I would do it. Again: feel free to complain, comment, judge. I hope I will show you few tricks here and there that will help you with next event, or at least: will help you understand what you might have done wrong. Not that I’m assuming you did, I just noticed few gotchas in this scenario that I wanted to addresses. Have I succeeded? As you probably already know, there is no definite answer to that question. 
Scripting Games is chance to learn things. You can learn by good example, or by mistakes, but often – mistake for one person is perfect solution for other. In PowerShell there are usually many ways to skin the cat, some of those I like – some, not so much. So what did I like and dislike so far? Here are few notes I made.
I think I blogged about it a while ago, but I still see people who assume that stating that their command SupportsShouldProcess is enough to implement –WhatIf and –Confirm. This is partially true. Namely: –WhatIf part will probably work just fine. Confirm will work fine too most of the time. When it will start to misbehave? When we start to use pipeline, or multiple cmdlets that SupportShouldProcess.
This year judges should focus on blogging. I’ve decided that it may be helpful to give attendees chance to return the favor – I will blog about things I like and dislike in your scripts. At the same time – I will post how I would do it. Feel free to complain, point out mistakes. I will try to post it as soon as entries are closed for submissions, so that I will do it “fresh” before I see any of your scripts – this way I won’t “steal” your ideas.
