If I want to create new taxonomies (e.g. Project / Documents / Etc...) is it better to create them in the theme's functions.php or within a plugin?
Where to put my code: plugin or functions.php?
Factorial Inequality problem $\left(\frac n2\right)^n > n! > \left(\frac n3\right)^n$ Custom URL Hack - anybody know how can i find the fields IDs from "User" object? I'm new in custom URL hacking.  I am trying to write a custom URL in a custom button. It is suppose to clone the User record, and while doing so, I want some user fields to be cleared. However, I need help identifying those fields IDs (e.g. Email, Name, etc).  How can i refer these fields when writing the custom URL code? How to explain dropout regularization in simple terms? $\varepsilon$-number countability without choice Let $\alpha\mapsto\varepsilon_\alpha$ be the enumeration of the $\varepsilon$-numbers--that is, those $\alpha$ such that $\omega^\alpha=\alpha$--by the ordinals.  If we know that countable unions of countable sets are countable, (slightly weaker than countable choice), then we can show fairly easily that $\varepsilon_\alpha$ is countable iff $\alpha$ is countable.  I think I saw a result at some point that $\varepsilon_0$ is countable without relying on any choice principle (though I can't recall where I saw that). Is this true? More generally, for which $\alpha$ can we conclude that $\varepsilon_\alpha$ is countable in ZF?  Update: I have been able to prove (in ZF) that if $\varepsilon_\alpha$ is countable, then $|\alpha|&lt;\aleph_1$, so that's one direction. I'm still a bit uncertain about the answers I've got so far. Friendly way to make previous large calculation results reusable in a new session Should 'Hi', 'thanks', taglines, and salutations be removed from posts? I edit a lot of posts every day. I often run across posts with 'Hi' and 'Thanks' on the top and the bottom of the post respectively. I also run across things like:     --User   Should these items be removed during the editing of the post by an editor? I had a tin of golden syrup for a long time - longer than I care to admit. When I opened it up yesterday (to sweeten up some mulled wine), it was granular (a bit like honey can be), and black around the edges.   Is this 'bad', or just different?   Is the blackness the result of some chemical reaction with the tin?  And in general, does it eventually go off, or does it last indefinitely? Combining randomForests in R, why are the err.rate, mse and rsq components NULL From ?combine in :     The confusion, err.rate, mse and rsq components (as well as the   corresponding components in the test compnent, if exist) of the   combined object will be NULL.   Why are the err.rate, mse and rsq components for the combined NULL? Is there an efficient way to re-calculate these metrics?  I ask because I would like to figure out a way to use the oob re-sampling method with the parRF model in . Toggle wireframe mode with hotkey What does the author mean by 'back to back' and 'hidden city' ticketing hacks? At this link about   what does the author mean by this?   Back to back and hidden city ticketing. Sometimes airlines will charge far more for tickets to that do not include a Saturday night stay, on the assumption that those passengers are business travelers who aren’t flexible and can afford to pay more. Yet those who commute between cities eventually realize that they can purchase one round-trip ticket that covers their first outbound and last return, followed by round-trip tickets to return home on the weekends. I want wp_link_pages (mutli-page posts) to display the page numbers, the word "previous" before those numbers, and a "next" after those numbers.  It would look like this:  Prev 1, 2, 3, 4 Next  I'm attempting to do this without a plugin.  Here's what I've tried so far, but it isn't working, it is only displaying numbers.  &lt;?php wp_link_pages(array(     'before' =&gt; '&lt;span style="clear:both; display:block"&gt;Pages',      'after'  =&gt; '&lt;/span&gt;',     'next_or_number'=&gt;'number',     'previouspagelink' =&gt; 'previous',     'nextpagelink'=&gt; 'Next' )); ?&gt; Installing firmware blob for Intel Wifi USB pen I have installed Debian 8/Jessie minimal ISO on my laptop. I get error message during system installation:  Some of your hardware needs non-free firmware files to operate. The firmware can be loaded from removable media, such as a USB stick or floppy. The missing firmware files are: iwlwifi-7265-9.ucode iwlwifi-7265-8.ucode If you have media available now, insert it, and continue. Load missing firmware from removable media?  I found the appropriate firmware on Debian website, downloaded it (zip), extracted to flash drive, and booted with flash drive plugged in. I still get the error message that appropriate firmware could not be found (the error message disappear to fast to copy down). How do I properly format the flash drive? Or is the problem here something else? Windows Explorer on another computer tells me the flash drive is 14.6GB and formatted as FAT32. /etc/shadow date of last password change—UTC or local time? man 5 shadow gives the following description of the third field in each line:  The date of the last password change, expressed as the number of days since Jan 1, 1970. The value 0 has a special meaning, which is that the user should change her pasword the next time she will log in the system. An empty field means that password aging features are disabled.  Does this refer to times in UTC or the local timezone? In particular, if I want to calculate comparable numbers using something like $(( $(date +%s) / 86400 )), do I need to pass date the -u option? How to show GRUB after install Ubuntu over Windows 8? I installed Windows 8 and after that I installed Ubuntu. This are my partition now:   70Gb --> Windows 8 50Gb --> Ubuntu 12.10 100Mb --> UEFI 300Mb --> Recovery   I installed the GRUB on /dev/sda. Then, after GRUB not showing up and booting directly into Windows 8, I turned the laptop off and booted again into Ubuntu LiveCD and ran the Boot-repair utility, it give me  but it didn't solved the problem.

When I view the same design on another monitor that I own, the colors seem drastically different. I reset both of the monitors to their factory defaults, but still the issue persists. I'm wondering if some of my clients might dislike my designs because of this. What should I do?  How can I make sure that what I design is what my client sees?  Even worse still, I've realized that my laptop is showing different colors too. I installed Windows on my computer, followed by an installation of Ubuntu. However, now I'm unable to boot into my Windows install.  What can I do to fix this? Proof of the formula $1+x+x^2+x^3+ \cdots +x^n =\frac{x^{n+1}-1}{x-1}$ The page I'm trying to fetch is public.

Book or web site resources for an absolute beginner to learn about stocks and investing? I'm completely new to the world of investing and stocks. Knowing that I shouldn't invest or buy stocks until I know it well enough, I was wondering which cheap or affordable resources would be the best to get started?

To narrow it down, what book and/or what website would you recommend that does a good job teaching investing in stocks to beginners?
