Can i enlarge an image without losing quality? You know, like in cool movies people do. Like so:
So I watched the following .  In the clip, using what seems to be the recording from a standard bank camera, they zoom in at least 100, and see the image of the culprit in the reflection of the eye of the girl.  Now, I thought this was completely ridiculous, so much so that I thought it was actually really funny.    However, my friend argued that there are very good tricks for image enhancement, such as "super resolution" a procedure where multiple frames of a video to produce a much higher single resolution image.   He did think the show bends the truth quite a bit, but how much?  Honestly, I don't actually know anything about these things, so my question is:     How good is modern image resolution enhancement?  Also, how far off are the CSI television programs?    Thank you,  Remark: This is  on the Skeptics site.  I was told I might receive better answers here.
How do popular free RAW editor/converter compare to each other on Windows? I'm looking for a free RAW editor/converter on Windows. Can you tell me some strong/weak points of them comparing with Capture NX and/or Adobe Photoshop Elements?       - conversion &amp; EXIF  - white balance  - registration not possible anymore   EXIF editing would be a nice bonus.  Related: Travel in the Schengen area after my residence card was lost or stolen I have already booked my flight from Italy to the Netherlands through Ryanair. I'm staying in Italy legally and have a carta di soggiorno. However, after booking my flight, my wallet was stolen, which contains all my IDs except my passport. I filed a police report, and I'm trying to get a new residence card. However, I need to go to the Netherlands ASAP. Will Ryanair accept the police report and receipt of getting a new residence card from the post office?  UPDATE (17.07.2014)  Thanks for helping me out. BTW it's OK now. I went to our local CISL here in Florence, Italy, where they process your envelope for renewing your permesso di soggornio or carta di soggiorno (residence permit for foreigners) to be submitted to the post office. That's where you pay and get your postal receipt, and they make an appointment for you at the questura. Anyway, long story short, they processed a application for IMPROVISED residence permit which is good for 30 days to travel within the Schengen area, so all I have to do is go to the questura, bring my travel booking, the police report and copy of my passport. Now I can travel, and it's my first time to fly with Ryanair because I always use Transavia to go to Holland. =) Hope this helps for future persons who will have the same issue with lost or stolen residence permits...Just wish me luck that the questura will process my improvised residence permit immediately. On iPhone it's very easy to clone an app (running multiple copies of the app on the same device); e.g.:    Is it possible to do this on Android? Prove 24 divides $u^3-u$ for all odd natural numbers $u$ At our college, a professor told us to prove by a semi-formal demonstration (without complete induction):   For every odd natural: $24\mid(u^3-u)$   He said that that example was taken from a high school book - maybe I din't get something, but I really have no idea to prove that without using complete induction.  Any idea of smart demonstration?  Thanks for your help. (Excuse my bad English.) I am new to Ubuntu. I am Using Ubuntu 18.04 along with Windows10. I have gone through the below Q&amp;A and could able to change the name of Ubuntu,      But   if i edit the Ubuntu OS name to my choice, it is then adding "GNU/Linux" at the end. for ex. if i want "Ubuntu 18.04" it is then showing as "Ubuntu 18.04 GNU/Linux". how to avoid this text "GNU/Linux" how to edit the name to my choice which is shown as "Windows Boot Manager (on /dev/sda1)"        Update: I Confirm about the text "GNU/Linux" is solved by @Terrance comments. I still need to try about windows entry.      Final Update: Solved.    I thank @Terrance, @Oldfred, @WinEunuuchs2Unix. All the three methods are working great. i felt the small script is awesome and very very easy to use. which is written by WinEuuuchs2Unix. Are Playstation 4 games locked to a certain region? This question has been asked before, but it was for PS3 and Xbox 360 and was asked August 2010. This time around my question goes specifically to PS4, since I'm moving from Mexico to Europe and I was wondering if the European games will run in my console or if I'll have to buy a new one. I never thought of this before (which is why I never paid attention if it was mentioned in reports or specs of the console) and the research I did wasn't too helpful. LaTeX for Microsoft Surface I have my new Microsoft Surface and I was wondering whether it's possible to install pieces of software like MikTeX and TexMaker on this tablet. Does anyone know? I use VirtualBox on my MBP and often need to mount my USB flash drive inside the guest.  The problem I'm running into is that the host OS (OS X Mavericks) immediately mounts the USB flash drive when I insert it.  When I try to unmount it (gracefully, through Finder), OS X complains that the device is in use.  Further research into lsof reveals that Spotlight and AVG are doing their thing with the flash drive.  Rather than fiddling with individual app settings, I'd like to just modify the host OS behavior so that the USB device doesn't auto-mount.  Any suggestions? Can I access the App Store from within the iOS Simulator? Super+D key shortcut does not show desktop I recently installed Saucy Salamander on my computer. Previously in Ringtail, Super+D used to show the desktop. However for this release, the Super+D does not seem to work properly... Is it a bug?

Prove that $a$ is algebraic over $F$ iff $F[a]=F(a)$.  For the first direction I've tried this: $a$ is algebraic over $F$ $\Rightarrow$ there is a polynomail $f$ over $F$ such that $f(a)=0$ $\Rightarrow$ $1,a,a^2,...,a^m$ are linearly dependent $\Rightarrow$ $\deg(F[a])&lt;m$.    but it contains $f(a)$ so they are equal..  is that correct? about the other direction.. i simply have no clue Prove that the sum of digits of $(999...9)^{3}$ (cube of integer with $n$ digits $9$) is $18n$ Someone had posted a question on this site as to what would be sum of digits of $999999999999^3$ (twelve $9s$ ) equal to?   I did some computation and found the pattern that sum of digits of  $9^3 = 18$,  $99^3 = 36$,  $999^3 = 54$ and so on. So, I had replied that sum of digits of  $999999999999^3 = 12 \cdot 18 = 216$.  Can anybody help me prove this, that sum of digits of  $(\underbrace{999\dots9}_{n\text{ times}})^3 = 18n.$ Why do people rule out local hidden variables? I bet the automatic response to my question would be "Bell's theorem" and of course I am not disputing Bell's proof. I am however uncertain of one of his assumptions.  The so called "no conspiracy" assumption states that we somehow posses this magical thing called free will which makes us able to break free from the causal chain of events that make us measure the $y$-axis instead of the $x$-axis and so on in experiments. Obviously this makes little sense once reviewed under the light of logic. What this naturally implies is that, if a theory is fully deterministic, it is instantly super-deterministic.  Simon Kochen and John Conway published a theorem in 2009, , which simply-put states: either everything is deterministic (super-deterministic) or every particle has free will.  Among the few who accept this to the fullest extent is Gerard 't Hooft. He has proposed that what we call sub-atomic particles are really just templates and that there is a realm beneath the quantum where the true fabric of reality is "hidden". By accepting determinism he escapes Bell's theorem (due to not having to accept the "no conspiracy" assumption) and can construct a local, deterministic and realist hypothesis of reality. In Gerard 't Hooft's model there is cellular automata somewhere near the Planck scale which gives rise to the "emergent quantum mechanics".  This means that there exist no superpositions in objective reality, the cat is always either dead or alive, no collapse of wave functions, no branching universes, non-locality or retro-causality.  The big question for me is basically: Why do people have such a hard time accepting determinism? Some will object and say "oh but it's SUPER-determinism", but that makes no sense whatsoever, either everything is determined (determinism) or only somethings are (quasi-determinism). By accepting it we escape Bell's theorem. Bell himself was well aware of this and mentioned it a few times in interviews in the 80's.  I know some are concerned that if we accept complete determinism we can no longer do science because it's all a HUGE CONSPIRACY. Gerard 't Hooft has answered critics who bring up this here: , section 6.  Additionally, another author who has taken a deeper look into the worries of "conspiracies" in QM interpretations is Peter J. Lewis in his paper  (also ).  So to all of you who dismiss local hidden variables I ask: Why? I'm looking to have cell borders automatically applied when a cell is not empty. I thought I could use conditional formatting for this, but it doesn't seem to be an option. How to tell how many CPUs (cores) you have on Windows 7 I have the task of creating a simple Excel sheet that takes an unspecified number of rows in Column A like this:  1234 123461 123151 11321   And make them into a comma-separated list in another cell that the user can easily copy and paste into another program like so:  1234,123461,123151,11321   What is the easiest way to do this?
