I want to build an app for android and ensure that the user can only use this app. (i.e. user should not be able to open or install any other app.) Is it possible to force such restrictions on an Android device ? And if it is where should I start ? What you are looking for is called the "kiosk mode" (just to help you googling the appropriate term). There is no such thing in the standard android api (at least... not yet : see the Edit ). User always have the ability to press the home button to come back to the Home application. But solutions exists: Writing an Home app This solution is a little

We have a Subversion repository with one directory that is: Not really in need of revision control beyond the capabilities of RCS Not versioned in conjunction with anything else in the repository Modified about six times as often as the rest of the repository Although I know that high revision numbers aren't a problem, nonetheless I'd like to pull this one single directory out of my main repository and into a second, ideally new one. What is the best process for that? If it makes a difference, the SVN repository is hosted on a (... checks... ) FreeBSD machine. It's worth noting that while I

This suits the requirement: select username, account_status, EXPIRY_DATE from dba_users

Can we setup passwords ssh that User A from Computer A to log into computer B using his User account(A). Thank you!! If I understand your question, can you set up ssh-keys to allow user A and user B to log into to two different computers A & B without providing a password? Sure, but user A can't log into user B 's account via ssh any more than user A can log into user B 's account on a local machine. (directory ownerships are different for the $HOME , etc..

I'm just getting started in PowerShell and one of my sysadmins told me that Powershell can do as much as C# can for systems management, if not more. Please forgive the ignorance of this question, but when would I use Powershell over C#? When I worked in the Windows build lab a LONG time ago (1997) the rule I was taught that if the code satisfies either of these two conditions write it in interpreted script, otherwise write it in compiled code: there's more overhead than code (using/include lines, function declaration, etc) there's a better than 10% chance that the code will change before it
