How can I switch from Survival to Creative?
Is it possible in Minecraft to switch over from survival to creative in single player?
Solving linear congruences by hand: modular fractions and inverses Itemize: Identation is different between first and second line variable-variables in PHP Ubuntu 12.04 on Amilo LA1703 after istalling graphics doesn't start? Can't move/snap Nautilus window to occupy left or right half of the 1366x768 screen - is it just me? Near the end in amongst the battle, Kylo Ren lands next to his ship that Rey stole. I understand that at a stretch (or through the will of the Force) Kylo found a TIE Fighter in the wreck he was in, but to my understanding those TIEs would not have had hyperdrives, so how did he travel that far without a carrier ship? I suppose I'm guessing/assuming that he travelled on his own (Solo if you will), and not with his Star Destroyer, as the Knights who travelled with him on his Star Destroyer were already at the destination. But if the Force willed him to find the TIE Fighter, why not a shuttle with a hyperdrive? It would be iconic enough to use in the film, surely.  How did Kylo Ren travel to another system in a civil war era TIE Fighter with no hyperdrive or carrier ship? "May I go to the bathroom?" and "I asked if I might go to the bathroom."   The modal auxiliary 'may/might' is used to ask permission.     "He may not have understood your question." and "He might not have understood your question."   The same modal auxiliary is used for uncertainty.  Why? The problem of counting the solutions $(a_1,a_2,\ldots,a_n)$ with integer $a_i\geq0$ for $i\in\{1,2,\ldots,n\}$ such that $$a_1+a_2+a_3+....a_n=N$$ can be solved with a stars-and-bars argument. What is the solution if one adds the constraint that $a_i\leq r_i$ for certain integers $r_1,\ldots,r_n$?  e.g. for $n=3$, $N=6$ and $(r_1,r_2,r_3)=(3,3,2)$, the tuple $(a_1,a_2,a_3)=(2,3,1)$ is a solution, but $(2,1,3)$ is not a solution because $a_3=3&gt;2=r_3$. Now that experience does something besides render regions of a server uninhabitable due to  orb lag, what's the most efficient and safe way to get those excellent enchants?  A mob farmer may rank highly, but what about without tons of setup? I have a webpage that implements a set of tabs each showing different content. The tab clicks do not refresh the page but hide/unhide contents at the client side.  Now there is a requirement to change the page title according to the tab selected on the page ( for SEO reasons ). Is this possible? Can someone suggest a solution to dynamically alter the page title via javascript without reloading the page? Is radioactive decay spontaneous or random? When it comes to radioactive decay, what is the difference between random and spontaneous?  For example, when the count rate of a radioactive isotope is measured, the readings fluctuate. Is this a demonstration of the randomness of the process, or of its spontaneous nature? I posted this question but for some reason I can't get back into my account:    Most things I see with 220V have both hot legs going through the switch or relay, current "returns" through the switch.  Is it against code to wire one leg directly to the equipment and the other leg is switched as opposed to having both legs switched.  It seems useless and a waste of wire to switch both legs.  Basically  vs  (minus the GFCI as I'm not allowed to have that)  As a bonus question.  I assume I need a "motor rated switch" as standard switches can weld due to the high startup current.  Is  one legal\safe? I have a Dedicated Bedrock Server running on my PC, and I can't connect from the same PC where the server is. If I add it onto the list of servers, it appears as "Locating server" and never finds it.    If I try to connect, I get "Unable to connect to world".    On my friend's PS4, it appears on the Friends tab as a LAN Game on a Dedicated Server.    And also on my sister's laptop. Finding center and radius of circumcircle Find the center and radius of the circle which circumscribes the triangle with (complex) vertices $a_1,a_2,a_3$. Express the result in symmetric form.   I'm not sure where to start in this question. The circumcenter is the intersection of the perpendicular bisectors, but I don't know how to calculate the line equation of the perpendicular bisectors yet. As for the radius, after we find the circumcenter $c$ we can calculate it using $|c-a_1|$ (or $|c-a_2|$ or $|c-a_3|$; all three should be equal.) So how can I calculate the circumcenter? Exercise $1.8$ of chapter one in Hartshorne. I don't understand why the interior of $\mathbb{Q}$ in $\mathbb{R}$ is empty, since, for every ball with the center being a rational number, given an $\epsilon&gt;0$, I can find an infinite sequence of rational numbers that approach this point. For example, take $\frac{1}{2}$. The sequence $\frac{1}{2}+\frac{1}{n}$ can be made as close as I want to the number $\frac{1}{2}$, therefore I can always have open balls with center $\frac{1}{2}$ such that there are rationals inside it. How can I reinstall GRUB to the EFI partition? How do I use the Natural Earth SQLite DB with QGIS? I just downloaded the Natural Earth data in SQLite format from . I had assumed that this would be a SpatiaLite database, but it appears not to be! QGIS is failing to recognize it as a spatial database. OGR supposedly supports reading geometries even when stored in a plain SQLite database, but maybe QGIS doesn't use OGR for SpatiaLite?  The SQLite database does have geometry_columns and spatial_ref_sys tables. Is there some way to convert it to a full SpatiaLite database? Is there a *simple* example of how the axiom of choice can lead to a counterintuitive result? "Cancellation", "Canceled", "Canceling" — US usage I'm trying to figure out if there is a specific rule behind the word "cancel" that would cause "cancellation" to have two L's, but "canceled" and "canceling" to have only one (in the US).    I understand the rules are very loose when it comes to double L's in English, and I have read several posts on here talking about "canceled" and "canceling" (vs "cancelled" and "cancelling"), but my specific question is more about the spelling of "cancellation".    - they do NOT mention cancelation with one "L"  - they do seem to have cancelation listed with one "L" Microsoft Word marks "cancelation" as an invalid word Same with the spell checker in Firefox   So my question is: is there a reason or rule why in US English, "cancellation" seems to have two L's (to most dictionaries), while "canceled" and "canceling" does not?
