Yeah it’s been a while since I’ve posted anything. I’ve been busy. This is nothing substantial, but I found it mildly interesting.
As part of device registration, it looks like Azure AD Connect creates a contact object in the configuration partition named “CryptoPolicy” and sets the employeeId attribute value to 365. I haven’t seen what it’s used for. It can probably just be deleted with no detriment (but don’t do that).
There are lots of “solutions” out there that just shell out to ntrights.exe or secedit or something else not powershell, and say “but powershell calls it so it counts!” No it doesn’t.
There is no native NET or COM interface to manage local user rights assignment. You have to use P/Invoke to call the API. It’s a pain. But I swiped some code from Roel van Lisdonk (http://www.roelvanlisdonk.nl/?p=1151) and got it working. Looks like he got the code from Willy Denoyette (see http://www.pinvoke.net/default.aspx/advapi32.lsalookupsids) which I kept intact except for a minor error correction (it was missing a semicolon and wouldn’t compile). See http://www.hightechtalks.com/csharp/lsa-functions-276626.html for what seems to be Willy’s original source.

Looks like there was an issue in the way my WordPress client posted the script last time, but that post has been fixed. One would think that pasting HTML in a rich text view would HTMLEncode it, but nooooo.
Any way, I’ve updated the function with some more info and streamlined the functionality. Here are some of what’s been improved:
In the future, I’ll be expanding this into a module and adding more functions. As before, please note that this uses code from the Managed Wifi API project (http://managedwifi.codeplex.com/) though slightly modified to make it suitable for PowerShell.

(Party game)
Get The Resistance on Amazon.com $13.94
The Empire must fall. Our mission must succeed. By destroying their key bases, we will shatter Imperial strength and liberate our people. Yet spies have infiltrated our ranks, ready for sabotage. We must unmask them. In five nights we reshape destiny or die trying. We are the Resistance!
The Resistance is a party game of social deduction. It is designed for five to ten players, lasts about 30 minutes, and has no player elimination. The Resistance is inspired by Mafia/Werewolf, yet it is unique in its core mechanics which allow for more informed decisions, wilder player interaction, and no player elimination.
Players are either Resistance Operatives or Imperial Spies. For three to five rounds, they must depend on each other to carry out missions against the Empire. At the same time, they must try to deduce the other players’ identities and gain their trust. Each round begins with discussion. When ready, the Leader entrusts sets of Plans to a certain number of players (possibly including himself/herself). Everyone votes on whether or not to approve the assignment. Once an assignment passes, the chosen players secretly decide to Support or Sabotage the mission. Based on the results, the mission succeeds (Resistance win) or fails (Empire win). When a team wins three missions, they have won the game. If you’re a Resistance Operative, expose the Spies as soon as you can; if you’re an Imperial Spy, lie and think quickly to sow distrust and confusion — either way, loud accusations and laughter are guaranteed as deceit and betrayals slowly come to light!

JAB: Realtime Boxing
(For two players)
JAB is a strategic boxing card game unlike anything you’ve played before. In JAB, you get direct control over your boxer’s fists, providing an experience as close as possible to real boxing without getting punched in the face. JAB is real-time. There are no turns. You can play as fast as you want, but remember: playing smart is more important than playing fast.
Has a real learning curve, the first few games you’re telling yourself, "WHAT THE FUCK, WHAT DO I DO?!" but once you get the hang of it, it is freakin awesome, and INTENSE 
Winning the game
To win the game, get a knockout by throwing staggering haymakers at your opponent until he eats canvas, or strategically win more rounds than your opponent by impressing the judges with your beautiful technique.
How is JAB different?
JAB re-invents the Real-time genre by slowing down gameplay and challenging you with strategic decisions. The innovative engine tests a player’s "strategic agility" by forcing constant quick decisions. It also measures your ability to calmly manage your focus, in a chaotic situation. The JAB engine is designed to be a develop-able skill, much like learning to play a fighting videogame, or even a real sport. Which also gives the game huge replayability.
Finally, you can beat up your friends and family, without the annoying assault charges and anger management classes!
JAB is a complete game, only one copy is required to play.
So how does the JAB engine work? (from a game design perspective)
The JAB engine can be broken down into a series of strategic real-time mini-games (mechanics), all running simultaneously. While focusing on all mini-games at once is almost impossible, all mini-games are equally important to win the game. A good player must not only be good at playing each of the mini-games, but also recognize which one he should be focusing on at any given time. A new player, much like a new boxer who steps into the ring for the first time, can easily feel overwhelmed and freeze up, priming his opponent for a knockout… so STAY CALM.
A Strategic Real-time Game? Pff.
No! It’s true! Every macro strategy or "style" in JAB, has a counter, like real boxing. See Boxing Styles and Techniques on Wikipedia for more info.
To counter a haymaker spammer, or slugger, a boxer must play like an outside-fighter, who focuses on counter-punching, and blocking, and points. An outside-fighter, like in real boxing, will be overcome by an in-fighter, who goes purely for combo points. An in-fighter boxer who is going for combos, will be knocked out by a slugger.
Every Boxer has a style, every style has a counter. What style are you?

Get Dixit Odyssey on Amazon.com $32.69
Dixit Odyssey is both a standalone game and an expansion for Jean-Louis Roubira’s Dixit, which won Germany’s Spiel des Jahres award in 2010.
Game play in Dixit Odyssey matches that of Dixit: Each turn one player is the storyteller. This player secretly chooses one card in his hand, then gives a word or sentence to describe this card – but not too obviously. Each other player chooses a card in hand that matches this word/sentence and gives it to the storyteller. The storyteller then lays out the cards, and all other players vote on which card belongs to the storyteller. If no one or everyone guesses the storyteller’s card, the storyteller receives no points and all players receive two; otherwise the storyteller and the correct guesser(s) each receive three points. Players score one point for each vote their image receives. Players refill their hands, and the next player becomes the storyteller. When the deck runs out, the player with the most points wins.
Dixit Odyssey contains 84 new cards, each with a unique image drawn by Pierô and colored by Marie Cardouat, artist of Dixit and Dixit 2. It also includes a folding game board, new rabbit scoring tokens, and a box large enough to hold all the Dixit cards released to date.
Dixit Odyssey includes enough components for up to twelve players and also has variant rules for team play and for new ways to play with the cards.
Also has a few expansions out: Dixit, Dixit 2, and Dixit Journey. All worth getting if you enjoy the game.

In this award winning party game, players sketch a word that’s dictated by the roll of a die, then pass their sketch on to the next player to guess what’s been drawn. That player then writes down what they think the word is, for the next player to draw a sketch of. Remember the classic game of Chinese Whispers? This is like that, but with pictures, and it’s proven to be very popular and lots of fun!

It’s a solid, cheap temperature controller that’s great for turning a chest freezer into a kegerator or fermentation chamber.
Didn’t see anything I wanted, but it makes sense.
I live in a college town and most student leases end on august 1st. Many of these people recently graduated and are flying to a new state, some are transferring colleges. Either way they need to get rid of stuff fast and have a deadline. This means a lot of people are selling a lot of stuff in the same window of time, which will bring down the asking price. Leave low-ball numbers with the sellers and tell them to call you if they change their mind. Sure enough desperate sellers will call you the day of their move.
Also its a good idea to check pawn shops about a week after the standard campus housing move out date
People also tend to just through away things out of laziness. You don’t even need to dumpster dive. Many times things such as mini-fridges are left right next to the dumpster. You can even just store them for a month and sell them to incoming freshmen

Got mold? It’s hard to get rid of. (i.e, the following is a summary of a recent nightmare I’ve endured). It can take weeks to remove all visible mold and prevent it from coming back.
First, solve the moisture problem; open windows more, install dehumidifiers or run air conditioner often, check plumbing / seals for leaks, check for entering rain water etc.
Get a cheap temperature/humidity meter or two and place them around your house. I got two that are solar powered (they run off indoor lights) for $15/ea at a hardware store. The relative humidity should be <55% for as much of the time as possible but preferably lower.
Then, clean away the mold with a HEPA filtered vacuum cleaner (on rough surfaces), or clean with bleach (hard surfaces, tiles etc) but this won’t KILL the mold.
Now, kill the mold spores which are remaining by buying some distilled (‘pure’) clove oil from Name Your Linkamazon or a health store. Put about 1/2 tablespoon of the oil into about half a cup of methylated spirits (or denatured spirits, different named in different places around the world) and stir. Dilute this to 1 liter with water and then wipe the moldy surface: WORKS AMAZING FOR MOLDY SHOWERS. Clove oil is an incredible thing!
Lastly, some things are essentially ruined by mold in most cases and cannot be treated; leather and carpets are two examples. Throw them out.
