Mac's dictation is a easy audio-to-text tool. however to change the language one has to go to system preferences every time. is there anyway to change between languages quickly(i.e by shortcut)? E.g if one can change dictation language by terminal, then alfred or shell script can change it with keyboard shortcut.
With English not being my first language, I usually need support for at least two languages when using features like auto-correct and dictation.  Is it possible to toggle the language which is used for dictation via a shortcut?  As of now, I always have to manually navigate through the menus in the System Preferences which if far from convenient. I've tried to see if there are any pre-defined actions in Automator, but found none.
How can I disable the "Open File Security Warning" when I want to run downloaded executable files? Remove particularly tricky items from context menu I've found various sources of info about removing these annoying things which I never use... but I haven't succeeded in getting rid of the following.    (Avira-related:) - Scan selected files with Avira  (I believe all this is M$ crapware... I presume it's all been lovingly crafted so they're all impossible to remove. You never know, though: some super-uber-uber-geek might just have found a way) - Restore previous versions  - Cut - Copy - Delete  - Rename What happens to the view.frame.size attribute after a CGAffineTransform (Rotate)? The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.  If this is the case how can anything ever fall into a black hole.  In my thought experiment I am in a spaceship with a powerful telescope that can detect light at a wide range of wavelengths.  I have it focused on the black hole and watch as a large rock approaches the event horizon.  Am I correct in saying that from my far-away-position the rock would freeze outside the event horizon and would never pass it? If this is the case how can a black hole ever consume any material, let alone grow to millions of solar masses.  If I was able to train the telescope onto the black hole for millions of years would I still see the rock at the edge of the event horizon?  I am getting ready for the response of the object would slowly fade.  Why would it slowly fade and if it would how long would this fading take?  If it is going to red shift at some point would the red shifting not slow down to a standstill? This question has been bugging me for years!  OK - just an edit based on responses so far.  Again, please keep thinking from an observers point of view.  If observers see objects slowly fade and slowly disappear as they approach the event horizon would that mean that over time the event horizon would be "lumpy" with objects invisible, but not passed through?  We should be able to detect the "lumpiness" should we not through? So I have a mac computer but i plugged in a windows keyboard in my mac. I am still trying to figure out how to paste commands into a command block. So how can I paste a command? Can I install a ROM made for a different device? I own a MicroMax A100. I want to install the latest version of a different ROM (Samsung or Nexus).  Is it possible? If so, can you tell me how?  If not, can I install a ROM made for a different device, but from the same manufacturer? For example, could I install a ROM for the MicroMax A110, which is the successor of A100? Combine the first two commits of a Git repository? Suppose you have a history containing the three commits A, B and C:  A-B-C   I would like to combine the two commits A and B to one commit AB:  AB-C   I tried  git rebase -i A   which opens up my editor with the following contents:  pick e97a17b B pick asd314f C   I change this to  squash e97a17b B pick asd314f C   Then Git 1.6.0.4 says:  Cannot 'squash' without a previous commit   Is there a way or is this just impossible? Proving $\int_{0}^{\infty} \mathrm{e}^{-x^2} dx = \frac{\sqrt \pi}{2}$ Is ignoring emails acceptable in academia? As a grad student, I just find it tremendously frustrating when emails are ignored by faculty (both at my institution and at other places). Is this acceptable? I'd be content with a simple response with one line along the lines of "I have read this email and am busy right now, will respond in X days when I can write a more detailed email." I understand that, as a first year student in my field, I'm not really in a position to request anything of anyone, but it just seems like common decency.  Instead, I never hear back, as if my email has been jettisoned off into oblivion. When I'm not exploring fresh caves or lands in minecraft, I'm busy trying to find deposits of diamond, gold and iron deep in the earth. So far I've just been digging around just above bedrock on a whim to look for these rare minerals but I've started thinking that I should be taking a more controlled, efficient approach to mining.  What is the optimal mining strategy that yields the most rare minerals while minimizing blocks removed and time spent digging and traveling?  Edit: The existing answers are great for mining, but no one has addressed travel time to and from the mine which is usually ~60 blocks downward and incredibly tedious. Solutions? It seems that Mac OS X 10.6.1 Snow Leopard has a tendency to leave some windows off-screen at times, especially when I disconnect an external monitor from my MacBook. How can I move the window back on-screen when it's not possible to grab the title bar and drag it back onto the screen?   recommends adjusting your screen resolution downward to have off-screen windows "snap back into view" and then adjust your screen resolution back to its original setting. In OS X 10.4 Tiger, I had a script that brought all off-screen windows back on-screen, but in my upgrades to Leopard and now Snow Leopard, I don't seem to have that script.  Any better solutions out there? Finite group for which $|\{x:x^m=e\}|\leq m$ for all $m$ is cyclic. Is it possible to earn more than 100 lollipops per second? I have pumped my lollipop rate to 100/s, but it took a long time to go from 99 to 100. Is it even possible to get higher or should I stop? How do I select background music for my RPG campaign? Music is an essential component of my games. When running games set in the Star Wars universe, the music of John Williams adds a new dimension to the experience, both for me and for my players. Now that I'm starting a fantasy campaign, I'm a bit more uncertain about which music to use.  How do I create a soundtrack suitable for using in a fantasy campaign?  Specifically:   What sort of characteristics make for good back ground music? What makes for bad background music? What should I look for to get a fantasy feel? Which genres/sub-genres support fantasy games? What are good sources for fantasy background music?   A few notes:   Because the music will be used in the background of game sessions, most of the tracks should be one minute or longer, to avoid repetitive loops. Likewise, soundtracks with a variety of themes are preferred, so that they can easily support different modes of the game: exploration, combat, and chases, to name a few. Orchestral or acoustic music is preferred over music with vocals or electric instruments. Discount for Roles I am using Drupal Commerce and I would like to know if it is possible to have discounted prices for registered users and much better for roles.  For example, the nomral price is $100 but when a user logs in that belongs to Role1 for example, he will see different prices with the percentage discount that I will have assigned to that role.  How can I accomplish such a feature? I'm kind of stuck in Terraria. I have full silver armor and 12 hearts (gold/silver gear).  I have just killed the Eye of Cthulhu.  I was thinking about gathering gold armor, but gold is damn scarce. I have tried searching for floating islands (at 406 altitude) but if I go to far I get attacked by Harpies, and I can't build a sky bridge and fight them at the same time.  My meteorite landed in corruption and it's impossible to collect it (I get swarmed by meteor heads with no way to run).  So what is the most natural progression? Should I try and find gold (where?), try to kill the Eater of Worlds, try to mine meteorite or try to fight off imps and collect some hellstone? It said  that:     [....] Rijndael can be specified with block and key sizes in any multiple of 32 bits, with a minimum of 128 bits. The blocksize has a maximum of 256 bits, but the keysize has no theoretical maximum.   How would the key schedule look for these other key sizes, like a 136-bit key? What is the difference between an int and an Integer in Java and C#? Why not use a WAMP stack? This is a  about  the use of a *AMPP's stack.    I recently had a talk with some experienced people and they suggested to me not to use a WAMP stack, and instead install apache, mysql and php separately.  I don't understand why they have suggested this, though, so can anyone tell me?  Is there a particular disadvantage of WAMP, or a particular advantage to installing all of them separately?  Since a WAMP stack itself is composed of apache, mysql and php, then what's the difference between using the WAMP stack and installing them all separately? dd vs cat -- is dd still relevant these days? I recently realized we can use cat as much as dd, and it's   I know that dd was useful in dealing with tapes where block size actually mattered in correctness, not just performance. In these days, though, are there situations where dd can do something cat can't? (Here I would regard a less than 20% performance difference irrelevant.)  Concrete examples would be nice!
