Can I enable pixel binning on Canon PowerShot G1X? On my camera, a Canon PowerShot G1X, I can select picture sizes from S to L.   Now I wondered, if I select a smaller picture size, that would theoretically lead to more sensor surface per pixel, possibly making the camera perform better in low-light or other 'harsh' conditions.   However, when I try this, I can't notice any difference in behaviour. The end result just looks like a resized version of the larger picture, and there are no differences in shutter speed and ISO to get to that result.  So, it looks like the camera just takes a large picture and then downscales it, which was against my expectations (or at least against my hopes).   Pixel Binning  The term that I think I am looking for is  also known as ,  or .   It certainly has advantages over downscaling by software, because it makes more efficient use of the hardware (faster reading, better noise reduction).  I think the answers below don't really answer my question. Neither do the answers of the supposedly 'duplicate' of this question, although the  came closest by at least suggesting that a camera might support this 'hardware-level binning', which allowed me to continue my search.  So far I couldn't find evidence that the Canon G1X supports binning, so I'm afraid it does not. But if someone know if it does (or maybe knows a hack or trick to enable it), please let me know. Previously I had a Canon PowerShot SII, and there was a way to install 3rd party firmware to unlock extra features. Maybe something like that is possible for the G1X as well?
Does it give higher quality to shoot in low-res mode in-camera, or to downsize high-res photos later? Suppose you want to store your photos at some lower resolution, let's say about ~1 MB large.  You own a camera able to make photos at 5 MPix and more.  And, you want to have the maximum quality at the smaller size.  Would it be better to make a photo at highest resolution and then resize it with PC software (with a good filter of course), or to directly set the camera to make photos at 2 MPix only?
Space faring human race encounters one highly advanced spaceship.  The one ship tells the human space fleet to go away and leave them alone. We don't listen and our ships are destroyed.  Human spy is sent to the alien world. Aliens look virtually identical to humans except they have no cartilage in their nose and the 'females' are only capable of mating every seven years. The human spy tells this story and is a brilliant tactician. He enters into a game tournament where they play a very complicated version of chess.  Human spy interacts with a higher ranking military officer who has a human female wife.  Human spy gets caught and when he is ultimately returned to Earth he advises humanity to unconditionally surrender to the alien race.  Humans eventually win because the alien males take human wives and their alien DNA is diluted in the vast human gene pool.  Looking for the title and author if anyone can recall them.  06/15 - update  I found the anthology. 'Second Game' was in 'The Arbor House Treasury of Great Science Fiction Short Novels' which came out in 1980 and 1981.  I did read the original story from 1958 which was actually a nominee for the Hugo Award for Novelette in 1959. Negative pressure How is negative pressure created in a fluid system?Isn't it counter intuitive that we are reducing the pressure of a system containing no molecules(zero pressure) to a lower value? How do I serialize a C# anonymous type to a JSON string? I'm attempting to use the following code to serialize an anonymous type to JSON:  var serializer = new DataContractJsonSerializer(thing.GetType()); var ms = new MemoryStream(); serializer.WriteObject(ms, thing); var json = Encoding.Default.GetString(ms.ToArray());    However, I get the following exception when this is executed:     Type   '&lt;>f__AnonymousType1`3[System.Int32,System.Int32,System.Object[]]'   cannot be serialized. Consider marking   it with the DataContractAttribute   attribute, and marking all of its   members you want serialized with the   DataMemberAttribute attribute.  See   the Microsoft .NET Framework   documentation for other supported   types.   I can't apply attributes to an anonymous type (as far as I know).  Is there another way to do this serialization or am I missing something? Can I use a card with "Add one mana of any color to your mana pool" in any Elder Dragon Highlander (EDH) deck? I recently tried /, and found it to be a ton of fun.  I've started customizing one of the pre-cons I got, but I'm a little confused by some of the deck-building requirements.  According to the deck-building rules:   A card's color identity is its color plus the color of any mana symbols in the card's rules text. A card's color identity is established before the game begins, and cannot be changed by game effects. Cards in a deck may not have any colors in their identity which are not shared with the commander of the deck. (The identity of each card in the deck must be a subset of the General's)    If I'm using  as my general, my deck's identity is Red, Blue and Green.  I couldn't use  in my deck, because it has a black mana symbol in the rules text.  My question is:  can I add a card to my deck that has the phrase "Add one mana of any color to your mana pool" (such as  or )?  Even though those cards could conceivably add black mana to my mana pool, they don't have a black or white (or any for that matter) mana symbol in their rules text, so they would be valid for inclusion in any deck? How to disable GNOME keyring? I want to disable GNOME keyring globally on my machine. So I deleted the lines  auth    optional        pam_gnome_keyring.so session optional        pam_gnome_keyring.so auto_start   in /etc/pam.d/gdm. It seems to me that this has no effect. When I lock in the syslog writes  Aug 24 18:37:03 foobar gnome-screensaver-dialog: gkr-pam: unlocked login keyring   and another user sees a menu window where he hs to enter his credentials. So what is the correct way to disable keyring for every user on that machine? How can I create an empty file from the command line? Is Firefox 57 multithreaded? According to  on MDN, Firefox 57 finally runs things in different processes.  So is Firefox 57 multithreaded?  In particular, how many cores does it use at most? Say I open 20 tabs at once on a quad-core machine, will Firefox 57 launch as many threads, or at least as many as needed to max out my CPU?  (Chromium for instance spawns a number of sub-processes and very easily uses all the resources available. Firefox up to 56 in GNU/Linux is rarely seen going over 135 % of one core however many tabs I open.) Is there any way to shorten URL in SMS in Marketing Cloud?

I am using the below code to populate hosted email link in email.  %%=RedirectTo(CloudPagesURL(383,'Id',@Id))=%%   In the message, it's showing up.        How can I shorten this URL? How does the double strike mechanic interact with other mechanics like lifelink or trample? I understand that the double strike mechanic allows a creature to attack in both a first strike combat damage step and a normal combat damage step.  It's clear that when a creature with no other abilities aside from double strike is blocked that even if the defender has lethal damage marked in the first strike step that the additional damage does not carry forward to the player.  How does this view of double strike change with relation to trample and lifelink?  I believe the correct interpretations are (not accounting for other effects or abilities) that 2 times the attacker's power is marked as damage on the defender.  For trample this amount is reduced by the defender's toughness and additional damage carries forward as normal.  Similarly for lifelink the active player gains life equal to 2 times the attacker's power.  Thus a 10/10 trampling double striking life linker blocked by a 1/1 creature would deal 19 points of trample damage and the active player would gain 20 life.  Is this interpretation correct? Can I convert flat bar to drop bars on a hybrid bike In naive set theory, I believe ∅ = {∅} = {{∅}} is correct, but just wanted to make sure that I understood this correctly.   ∅ is an empty set, so having an empty set as an element of a set that contains nothing else is pretty much the same thing as e.g. marking the number 2 as 2.000000, right? Doesn't the symbol ∅ intrinsically imply that this is an empty set which contains it self? When reviewing Suggested Edits on Stack Overflow, I often come across "fixed formatting" suggestions that use  to place emphasis on certain keywords, but isn't actual code.

Non-principal ideal in $K[x,y]$? Let $K$ be a field. Then $K[x,y]$ is not a PID because $x$ is irreducible but the quotient $K[x,y]/(x)$ is isomorphic to $K[y]$, which is not a field.  So there must be an ideal in there which is not principal. What is an example of such an ideal? Quotient group $G/H$ is abelian iff $[G,G] \subseteq H$ After 4 years of being a Mac user, there is only one thing that I still miss from the Windows world, and that is being able to switch with a single keystroke between all open windows in the computer.  What is the best app or utility, free or not, for accomplishing that?  I've used , but I never was completely satisfied with it. It's a bit slow and the switcher UI is not very pretty.  Do you know any alternative?    EDIT (2016): This question keeps getting views and upvotes after 6 years. When I asked this question in 2010 I was still transitioning from being a Windows user. Eventually, I got used to Mac OS X UI and nowadays I don't use any third party utility for managing app windows, just Mission Control and the native keyboard shortcuts. So, although this question is no longer relevant for me I hope it is useful to new Mac users making the switch (Including this comment). Searching for an equation to find the center of a sphere given 4 points, one finds that taking the determinant of the four (non-coplanar) points together with the variables $x$, $y$, and $z$ arranged like so:  $\left|\begin{array}{ccccc} x^2+y^2+z^2 &amp; x &amp; y&amp;z&amp;1\\ x_1^2 + y_1^2 + z_1^2 &amp; x_1 &amp; y_1 &amp; z_1 &amp; 1\\ x_2^2 + y_2^2 + z_2^2 &amp; x_2 &amp; y_2 &amp; z_2 &amp; 1\\ x_3^2 + y_3^2 + z_3^2 &amp; x_3 &amp; y_3 &amp; z_3 &amp; 1\\ x_4^2 + y_4^2 + z_4^2 &amp; x_4 &amp; y_4 &amp; z_4 &amp; 1\\ \end{array}\right| = 0$   yields the equation for the sphere.  Then one need only re-arrange terms into the more familiar form to find the center and radius.  This works fine.  My question is why.    This same approach also works for one or two dimensions.  I'm guessing it also works for finding hyperspheres in higher-dimensional spaces as long as you have a corresponding number of points.  But where did that determinant form come from?  Is there an intuitive meaning for what that relationship is saying? $\sum k! = 1! +2! +3! + \cdots + n!$ ,is there a generic formula for this? I came across a question where I needed to find the sum of the factorials of the first $n$ numbers. So I was wondering if there is any generic formula for this? Like there is a generic formula for the series: $$ 1 + 2 + 3 + 4 + \cdots + n = \frac{n(n+1)}{2} $$ or $$ 1^{2} + 2^{2} + 3^{2} + 4^{2} + \cdots + n^{2} = \frac{n(n+1)(2n + 1)}{6} $$  Is there is any formula for: $$ 1! +2! +3! + 4! + \cdots + n! $$ and $$ {1!}^2 +{2!}^2 +{3!}^2 + \cdots + {n!}^2 $$?  Thanks in advance. If not, is there any research on making this type of formula? Because I am interested. With Windows 7, why is an entry in the hosts file not working?
