Question on isomorphism of finite field
Ring homomorphism and characteristic
Do I need a transit vsa in Kuwait; what about checked baggage? Can you lookup a domains past nameserver & mx record history? Is it acceptable to change colors on a logo to make it fit a website's theme? I have a few payment brand images that need to go in the footer of a website, the footer is very dark grey, to the point where making the logos grey-scale wouldn't be much of a good idea, especially as we still need the logos to stand out.  For example I took the following logo:   And changed it to fit with our very dominant red theme:    Is this good in terms of the user's perspective? Is this legal or misrepresenting the brand? If so is completely changing a logo to white acceptable for dark backgrounds? How to remove the Unity Amazon package in 16.04? I was able to go to the ubuntu software center before and remove it and now it doesn't show up since the switch to the gnome software store. Trying the terminal method of removing the shopping lens doesn't work in this release. Looks like flagging has been affected by releases today. Are these intended effects?   Higher daily limits (appear doubled for me, flagging of posts limit also doubled).  Explained by Shog9 below. Soft comment deletion  - e.g. for "accept rate" obsolete comments - it does in fact work, but the immediate feedback is gone.  This is fixed now. Has the throttling rate changed?  Seems possible to repeated flag without waiting 5 seconds.  If it was broken, it isn't anymore. Old soft deletions that were neither categorised as "helpful" or "declined" have all become "helpful".   If limits have been updated, can we get the new formula published? Not changed, as confirmed by Shog9. Prove that if prime $p$ divide $a_{2k}-2$, then $p$ divide also $a_{2k+1}-1$. Is it possible to apply modifiers to multiple objects at once? Alternating binomial sum with intervals of two Fix integer $n\geq 1$. Consider the number $$1-\binom{n}{2}+\binom{n}{4}-\binom{n}{6}+\cdots$$where the sum continues as long as the lower number in the binomial is $\leq n$. Is there a way to simplify this sum?   The first few values are $1, 0, -2, -4, -4$. How to find out what init mode system is using? I was looking at this and I'm not sure how to find out which startup service is used on my machine (Ubuntu 14.04 on Digital Ocean). Can it use all of them? (upstart, system v, systemd) Flexslider view preview working but not on actual page My block is not working for the flexslider: The images are not appearing, but the view preview does work.  I don't know if it is relevant, but a similar problem would happen with just a slideshow view, although one image would appear and it would not cycle.  Could jQuery be a problem?  The following is the actual page with the block that is not showing any images.        The following is the view preview, which works. How can reincarnated souls be summoned using Edo Tensei? Quoting ,     Reincarnation is the philosophical or religious concept that an aspect of a living being starts a new life in a different physical body or form after each biological death. It is also called rebirth or transmigration, and is a part of the Saṃsāra doctrine of cyclic existence.   Then, since Ashura has reincarnated into Naruto, and Indra into Sasuke, how can Uchiha Madara and Senju Hashirama (their previous reincarnation) be summoned using Edo Tensei? Will Area 51 be supported in the app? When should I use "shall" versus "will"? Will the Garbage Collector call IDisposable.Dispose for me? How to make clickable links and cross-references in pdfs produced by LaTeX? What is the name of the vertical bar in $(x^2+1)\vert_{x = 4}$ or $\left.\left(\frac{x^3}{3}+x+c\right) \right\vert_0^4$? I've always wanted to know what the name of the vertical bar in these examples was:  $f(x)=(x^2+1)\vert_{x = 4}$ (I know this means evaluate $x$ at $4$) $\int_0^4 (x^2+1) \,dx = \left.\left(\frac{x^3}{3}+x+c\right) \right\vert_0^4$ (and I know this means that you would then evaluate at $x=0$ and $x=4$, then subtract $F(4)-F(0)$ if finding the net signed area)  I know it seems trivial, but it's something I can't really seem to find when I go googling and the question came up in my calc class last night and no one seemed to know. Also, for bonus internets; What is the name of the horizontal bar in $\frac{x^3}{3}$? Is that called an obelus? Including Bitmap (.bmp) I can't include bitmaps with pdflatex.
