A note of caution: when installing the Fortinet SSO Agent on a server, the option to secure connections from a FortiGate with a password is enabled by default, and a random password is assigned.
You have to turn off or change the password before you add the SSO agent in your Fortigate.
There's no mention of this in the manuals, so now you know...
A bit of a hidden feature in Windows 8: you can actually "quit" Windows Explorer.
Right-click the (empty) taskbar while holding down Ctrl+Shift to reveal Exit Explorer as an additional menu item. Clicking it will then end Windows Explorer, leaving you with a blank screen, same as ending explorer.exe from the task manager.
You can then call up task manager (Ctrl+Shift+Esc), and start Windows Explorer again (File > Run > explorer.exe).
For some time now, installing/updating Java prompts you to install the Ask.com toolbar and search page. After installation, this is offered each time you install a new update of Java, which can be very annoying. A somewhat undocumented feature is that you can disable these offers from the Java Control Panel, preventing future updates from prompting you to install this thing.
For debugging purposes, I often prematurely abort a function by adding a return statement in the middle of it. With most compilers this works flawlessly, accept with Java...
The Java compiler bums out with an unreachable statement error, and won't allow you to compile a class until all code is reachable within a function.
Luckily, you can trick the compiler by adding an if-statement that's always true:
if (1==1) return;
This way, as the return is supposedly conditional, and the compiler doesn't consider the result of an if-statement, it is tricked into believing the following code is still reachable.
A nice article about how to set up NIS on Red Hat linux: http://bradthemad.org/tech/notes/redhat_nis_setup.php.
When attempting to log on with a domain account on a computer joined to a domain that has both 2012R2 and 2003 domain controllers, you may encounter the following error:
Additionally, an Event ID 4 on Source: Kerberos is logged. You can only log on using local accounts.
Mixed 2012R2 and 2003 AD environments require hotfix 2989971 to be installed on every 2012R2 DC. See the KB for a full explanation.
