I'd like to move the discussion from  into a chatroom. I created a chatroom (in &quot;Gallery&quot; mode), and under the &quot;Access&quot; tab is a section labelled &quot;Explicit write access&quot;, which says:  Even when this room is read-only or their reputation is too low, these users will be able to talk in this room.  Which sounds like exactly what I want, because the user asking the question has a reputation of 5. Unfortunately, if I try to grant the user write access to the room, I get the &quot;Users must have at least 20 reputation to talk&quot; error. ...which I knew, and is why I'm trying to grant explicit write access because &quot;their reputation is too low&quot;. Is there no way to have a conversation with a low-reputation user outside of comments?
It was nice to discover the option for a room owner to add any user to a room, even if their rep is too low.     ...so I notified the user in question, and as instructed on the next screen, I had them got to chat.stackoverflow.com so that I'd be able to add them.    ...but when they did their part, and I did my part, I got the message:    Obviously both frustrated, the user's next logical question was:  "So I just have ask a couple questions and get someone to upvote them, right?"    Needless to say, we don't want to encourage new users to post questions for the sole purpose of bypassing a frustrating, misdocumented rule.  I realize this will likely quickly get closed since it has at least one  - which hasn't been touched in 5½ years.  However it would be nice if the issue was revisited:  Ideally, it would be cool if RO's did have the option of deciding who had access to the room they "own", but short of that, is it possible to remove the 6 "misleading" words from that page?
Customized prompt does not hold when a child bash is ran I have been learning bash, and while doing so I played around with the .bash_profile file to be able to put greeting messages etc. Later I just removed these changes. But after doing that my default configuration of prompt got lost: originally, the prompt was all in bold, and \w part was blue so that when I was in a deeply nested directory the prompt would not seem so entangled. I think that was the default for Ubuntu (correct me if i'm wrong), however like  I said it got lost and my prompt was non-bold and monochromatic resulting in a mess when I'm in long named directories.  So, last night I tried customizing my prompt in the fashion I mentioned above. It worked well after I added the code to .bash_profile  Code was like this:  export PS1="\[$(tput bold)\]\u@\h:\[$(tput sgr 0)\]\e[1;34m\w$ \e[m"   However if I try to run another bash shell in the current one, the prompt becomes unformatted:    Is that normal? Isn't the whole point of exporting a variable to make it accessible from all the child processes forked from that shell? Why it doesn't that apply to this situation? Can you trip as part of a Tome of Battle Maneuver? If a ToB Maneuver such as Daunting Strike calls for a melee Attack as part of the maneuver, can this melee attack be resolved as a trip attack/include a trip attempt? Why is "that"/"which" omitted in this sentence? Is Pauli-repulsion a "force" that is completely separate from the 4 fundamental forces? How does apt-get really work? Okay, I understand how I may use apt-get {install|upgrade|remove} mypackages to install, upgrade, or remove binaries as well as their configuration data files and dependencies (actually, remove will only remove the binaries unless additional flags are provided).  I am not looking for how it is used as the man describes this, but high level what it is doing.  My end goal is to create a means for me to install and manage some custom software (created by a make file) on multiple remote machines, and I need to learn more about the process.  If answers to this question are based on which distribution is used, please tailor to Debian.  In addition to generally how it works, I have the following specific questions:   How does the client that is accessing the apt repository keep track of the files? Must the repository be hosted on the same operating system (i.e. can apt repository be hosted on redhat)? How are the locations to install files specified?  Is this specified by the .deb file? How is a remote machine accessing the repository?  Is it just ftp(s) or http(s)? Is the machine that is hosting the repository running special software (like gitlab for a git repository), or is it just some structured file system? strange character replacement on SO I added a comment to  but something strange is happening.

LaTeX multi-character subscript Proof that Epicycloids are Algebraic Curves? Epicycloids are most commonly described by the parametric equations,   $x(t) = (R + a)\cos(t) – a \cos \left(\frac{R + a}{a} t \right),$  $y(t) = (R + a)\sin(t) – a \sin \left(\frac{R + a}{a} t \right).$  Where $R$ is the radius of the fixed circle and $a$ is the radius of the rolling circle.   With $R = ka$ we also have,   $x(t) = a[(k + 1)\cos(t) - \cos((k + 1)t)],$  $y(t) = a[(k + 1)\sin(t) - \sin((k + 1)t)].$  Several books discussing epicycloids mention that if the ratio of the radii of the circles $\left( \frac{R}{a} = k \right)$ is rational, then they are algebraic curves. However, I’ve only been able to find the Cartesian equations for the cardioid, nephroid and ranunculoid. With the cardioid being,   $(ax + x^2 + y^2)^2 = a^2(x^2 + y^2).$   The nephroid,   $(-4a^2 + x^2 + y^2)^3 = 108a^4y^2.$  And the ranunculoid,   $-52521875a^{12} – 1286250a^{10} (x^2 + y^2) – 32025a^8 (x^2 + y^2)^2 + 93312a^7 (x^5 – 10x^3y^2 + 5xy^4) – 812a^6 (x^2 + y^2)^3 – 21a^4 (x^2 + y^2)^4 – 42a^2(x^2 + y^2)^5 + (x^2 + y^2)^6 = 0.$  Clearly this doesn’t cover all epicycloids where $\frac{R}{a}$ is rational.   What is the proof that shows that epicycloids, where the ratio of the radii are rational, are algebraic curves? There's more gravitational force in our galaxy (and others) than can be explained by counting stars made of ordinary matter. So why not lots of dark planetary systems (i.e., without stars) made of ordinary matter? Why must we assume some undiscovered and unexplained form of matter? After running Win 7 for some unknown period of time, the taskbar icon highlight starts to stick (video demo here: ). If I restart or kill explorer.exe and relaunch, it goes away.  Any idea what might be causing this? What is the best way to remove and prevent leaf stains on concrete pavers? Knowing which java.exe process to kill on a windows machine When a java based application starts to misbehave on a windows machine, you want to be able to kill the process in the task manager if you can't quit the application normally. Most of the time, there's more than one java based application running on my machine. Is there a better way than just randomly killing java.exe processes in hope that you'll hit the correct application eventually?

Allow Documentation in other Stack Exchange communities I'm a Salesforce developer and would love Documentation to be available in other Stack Exchange communities. The reason is  a lot of Salesforce developers get help, especially newer ones like myself. The developer forums and documentation on  is mediocre.

What is the solution to this instance of Apple's poor engineering?  Running macOS High Sierra 10.13.4 (17E202) Why is it bad practice to test for item names? I've heard that testing for item names and lores in Minecraft JE is bad practice. For example, the following commands are not good: execute if entity @e[nbt={Inventory:[{tag:{display:{Name:'[{&quot;text&quot;:&quot;Test Thing&quot;}]'}}}]}] clear @p minecraft:diamond{display:{Name:'{&quot;text&quot;:&quot;Shiny…&quot;}'}} 0 clear @p minecraft:netherite_sword{display:{Lore:['{&quot;text&quot;:&quot;A Mysterious Sword&quot;}']}} 0  Why are these commands considered bad practice? Are they prone to failure and may not work? And what can I do to fix them? Note that this only applies to reading item names, not setting them. The following are not considered bad practice and in fact are the only ways to accomplish these tasks: give @p minecraft:diamond{display:{Name:'{&quot;text&quot;:&quot;Shiny…&quot;}'}} replaceitem @p weapon.mainhand minecraft:netherite_sword{display:{Lore:['{&quot;text&quot;:&quot;A Mysterious Sword&quot;}']}} The set of real numbers and power set of the natural numbers I have learnt that the cardinality of the power set of the natural numbers is equal to the cardinality of the real numbers. What is the function that gives the one-to-one correspondence between these two sets?  I have also learnt that there exists no set whose cardinality is strictly between the natural numbers and the real numbers. Is there a proof of this or at least some intuitiveness behind it? Log4Net "Could not find schema information" messages How do you do AppBar docking (to screen edge, like WinAmp) in WPF?
