Something that's been needed for years and it's finally delivered. Also it's moronically easy to setup. Also, definitely learn 2012/2012R2. The vast majority of the information about the services it provides is going to be applicable back to 2008/2008R2. The basics of DHCP, DNS, AD, File Shares, Group Policy, etc don't really change significantly from version to version. Learn how to work with them and what they do/how they work and you'll be in a good spot whatever the specific server version is. Also, learn powershell. No longer must you be laughed at by Unix SYSAdmins who script their entire jobs. You may now laugh at them for having to parse text constantly while you pass objects around between scripts/functions!

Question for the thread, Aside the lack of hardware support (nvidia) are there any technical limitations why more games couldn't be run on linux?

Tab8715 posted:Question for the thread, most current games are being written using DirectX under the hood. DirectX doesn't really exist on Linux except through 3rd party "Not-An-Emulator" software that typically lags behind in feature support. Plus the game developers aren't focusing on cross platform support so they do various things that may not be cross compatible. At least that's my general understanding.

Tab8715 posted:Question for the thread, I'm going to guess developers don't want to use different APIs for graphics for one. For the most part, studios are going to overwhelmingly go with DirectX rather than doing an OpenGL port as well. And Nvidia does have hardware support, but it usually lags and is a binary blob which is anathema for most Linux users.

OpenGL is less popular in gaming than it used to be, but it's still out there. There's an incomplete list of notable apps that use OpenGL on Wikipedia. Any game with a Mac port uses it pretty much by definition since D3D doesn't exist over there.

OpenGL only covers the graphics, naturally enough. Plenty of games use OpenGL for graphics and then use Direct(other things) for other subsystems meaning they're still hard to port.

Not other commands, any text. Like if you have a log file with a berjillion entries and you want to find every instance of "Wakka wakka" followed by 47 characters followed by a date, you can write a regular expression that describes that pattern. The patterns can get as complex as you'd ever want. The problem is that the syntax is heinous and you can very very easily write a regular expression that almost matches what you want, or matches what you want and other things you don't want, and it's not always apparent where the problem is or even that there's a problem at all. They're also very hard to read, if say you need to go back and change a regexp you wrote a while ago or just figure out one that someone else wrote.

There's a notorious regex, like, a page long, used for checking email addresses to make sure they're actually email addresses. Really, any situation where you need to match some sort of pattern is something that regex can conceivably be used for. Personally, the one time I've used regex was to strip 'http://' or 'https://' from the starts of URLs, while leaving any URLs without a scheme (immediately beginning with 'www.domain.com', etc) intact.

"Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems." - jwz Regexes are pretty confusing when you first start with them, but definitely worth learning if you write any amount of script or code that parses text. They're just ridiculously powerful. Heck, you don't even have to write code to run into use cases. Most nontrivial Apache configs will have them embedded in rewrite rules or ACLs as one example off the top of my head.

Also it's moronically easy to setup. Please don't run a DHCP server on Windows, use your L3 switch or router. Also you might as well learn 2012 because one important point is that a Server 2012 R2 Datacenter license and unlimited client CALs is built into the cost of spinning up a virtual server on Windows Azure, Microsoft's cloud service. I got the 1 month Azure trial and spun up 2012 servers and created a domain and joined PCs to it over VPN. It takes a day or two of Googling and then you can blow away the execs at your job when you tell them you know how to run a whole domain from the cloud, when it's not really a big deal.

I'm not teaching a helpdesk person how to log into a switch to look at a text enumeration of DHCP leases, it's a lot easier to give them the DHCP MMC. Plus having all these little decentralized DHCP address pools all over the place is loving stupid.
