I apologize if this has been answered already. I've spent several hours searching through the WordPress directories and documentation, and I haven't been able to find the code for the default Gutenberg blocks. Could anyone point me in the right direction? To clarify, I am specifically wondering where in the directory tree of a WordPress installation the blocks are defined.
Apparently, at one time, there was a directory of core-blocks for building Gutenberg templates on GitHub, but I'm not finding it anywhere. I talking about core/paragraph, etc.     array( 'core/paragraph', array(         'placeholder' =&gt; 'Content goes here',     ) ),     array( 'core/image', array(         ...  Thanks!
I am using Ubuntu 16.04, with Gnome 3.18. Using extensions I have gotten rid of the dash panel and only use the Applications Menu in the upper left-hand corner of the screen. (I don't have Unity.) What I can't figure out is how do you add a new program, move software around to different categories, and create new categories?  Also, any keyboard shortcut to access the Applications Menu? sum of the residue at all poles of the rational function p/q is 0. We are given two polynomials p, q with deg(q)>1+deg(p). Show that the sum of the residue at all poles of the rational function p/q is 0.   How do I go about solving this? Character of the subobject classifier in the topos of $\mathbf{M}$-sets. Find all functions $f(x)$ such that $f\left(x^2+f(y)\right)$=$y+(f(x))^2$ How does a half-life work? Carbon-14 has a half-life of 5,730 years.  That means that after 5,730 years, half of that sample decays.  After another 5,730 years, a quarter of the original sample decays (and the cycle goes on and on, and one could use virtually any radioactive isotope).  Why is this so?  Logically, shouldn't it take 2,865 years for the quarter to decay, rather than 5,730? Polynomial contrasts for regression I cannot understand the usage of polynomial contrasts in regression fitting. In particular, I am referring to an encoding used by R in order to express an interval variable (ordinal variable with equally spaced levels), described at .  In the example of , if I understood correctly, R fits a model for an interval variable, returning some coefficients which weights its linear, quadratic, or cubic trend. Hence, the fitted model should be:  $${\rm write} = 52.7870 + 14.2587X - 0.9680X^2 - 0.1554X^3,$$  where $X$ should take values $1$, $2$, $3$, or $4$ according to the different level of the interval variable.  Is this correct? And, if so, what was the purpose of polynomial contrasts? When I use a multiclass move to choose Animal Companion, do I get Command for free? Benefits of Toad houses I have a few red Toads and a Toad is just hanging out in town. I see an option to buy a red Toad house, ostensibly for him. Are there any added benefits of purchasing this or are the colored Toad houses just cosmetic? Server vs single-player world effects Are there any differences with regards to chunk generation or other settings in single-player vs server mode of equivalent versions?  I have a map I'd like to host on a private server for my friend to play with me. However, when I'm on the road without ready internet, I'd like to play it single-player as well.  Will this cause any issues, especially with chunk generation, drops, items, etc (i.e., getting a different chunk generated in server-mode than single-player would have created), or do all server-client version pairs (I'm using 1.6.2) use the same game code?  The main point is that I don't want gameplay to change at all, between single-player and server mode. How to Edit PDFs? An idiom for deriving pleasure from another's suffering I believe it is what the Germans call "". English itself has no such equivalent word. (Although it has been adopted as a .)  Does an idiom exist that describes it? How can I replace a relay with a MOSFET Transistor? I have this working         &ndash; Schematic created using   An Arduino commute both relays and a power adapter charge each battery at a time.  I would like to replace each relay by a MOSFET. How can I do that?  I think the solution bellow will not work because DRAIN is always connected to SOURCE and this will short circuit batteries. MOSFETS only isolate from SOURCE to DRAIN.  When the D9 is HIGH, D10 will be LOW so the power adapter will never be charging both batteries simultaneously.          Sorry for the messy schematic.  Thank you very much. Error in Obj-C : Expected identifier or '(' Can you cast a spell at a higher level, even if it doesn't have an "At higher levels" entry? Many spells have "At higher levels" that provides for more targets or more damage.  For example Magic Missile can be cast as a second level spell and shoot 4 missiles instead of it's 3 as a first level spell.  Can a spell without that verbiage, such as Firestorm be cast in higher level slots for the same effect as the lower level spell? How can I extract a page range / a part of a PDF? Do you have any idea how to extract a part of a PDF document and save it as PDF? On OS X it is absolutely trivial by using Preview. I tried PDF editor and other programs but to no avail. I would like a program where I select the part that I want and then save it as a PDF file with a simple command like CMD+N on OS X. I want the extracted part to be saved as PDF and not as JPEG, etc. Using X11 in OSX 10.8.3 : "ld: library not found for -lX11" Converting string arrays into Map Build and strengthen the Stack Exchange community with "crossover questions" between sites I've been a Stack Exchange contributor for a couple of years now, currently most active on . One thing that keeps coming up is questions that would appeal to audiences on two different Stack Exchange sites but there are almost no features taking advantage of these questions. On travel.SE we have crossover questions most often with  and possibly next most often with  - but it can happen with almost any SE site. Today alone we had  with  and  had . I am absolutely sure that this must happen all the time between arbitrary pairs of Stack Exchange sites but the only feature that takes advantage of it is the possibility of migrating off-topic questions which leaves the original question acting as a redirect across the two sites. I think there is a missed opportunity to build the network between sites where users of one site don't realize they could make valuable contributions to a sister site they have had so far little to do with. At the very least there could be a way to &quot;advertise&quot; a question on a second site that could be interested in it. Probably by listing it in the sidebar where there are also links to meta questions, linked questions, related questions, new blog posts, and But there could also be some kind of features that make some sort of acceptable crossposting. There could be gamification/badges added around building cross-site questions or whatever else you can think up. I think this is a great way for people to spread their expertise from their main site onto other sites, to make the network stronger and more cohesive, to bring more attention to questions that would have a divided audience between two sites. I can think only of positives and no negatives. Does anyone else have some ideas to add or think this is a bad idea for any reason?  Example crossover questions: Here are some links to some crossover questions I've been finding in the Stack Exchange network here. (This was previously posted as an answer, but more people wanted it to be part of the question.)   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  :   ▶  : $a =\prod_{i = 1}^{r} p_{i}^{ai}$ with $a_{i} > 0$ for each $i$ is the canonical representation of $a$... I have been working with a string[] array in C# that gets returned from a function call. I could possibly cast to a Generic collection, but I was wondering if there was a better way to do it, possibly by using a temp array.  What is the best way to remove duplicates from a C# array?
