Just now I saw a user with a banner on his/her profile page that says the user is suspended until '18.  Right now, it is 2019.  The user should have been set free last year, but for some reason he/she still appears to be suspended with only 1 reputation.          Why is the user still appearing to be suspended?  It seems to be a kooky error to me.  Can anyone please try to fix this bug, or at least explain to me what is going on?  -
I came across a user with a notification that states:     This account is temporarily suspended network-wide. The suspension period ends on Dec 2 '18 at 2:35.   Screencap for posterity:    Unless this user is  (in which case the full year should be shown, or at least a tooltip), it seems like they should have been unbanned 4 months ago.

Understanding the Basic Context of Trusted Hosts I got the trusted host settings error.      The trusted_host_patterns setting is not configured in settings.php.

Detecting and acting on keyboard direction keys in Java Can a Druid/Barbarian multiclass wildshaped into a giant constrictor snake use my Athletics skill in the place of the constrict attack? Can a Druid/Barbarian multiclass wildshaped into a giant constrictor snake use my Athletics skill in the place of the constrict attack?  A barbarian/druid multiclass can have a much better grapple than a lot of wild shapes have specialized grapple DC set to (especially when including feats like Prodigy to get expertise in Athletics).   Would I be resigned to using the animal's DC for those special attacks, or can I use an Athletics check instead? How to use SSH to run a local shell script on a remote machine? I have to run a local shell script (windows/Linux) on a remote machine. I have SSH configured on both machine A and B. My script is on machine A which will run some of my code on a remote machine, machine B. The local and remote computers can be either Windows or Unix based system. Is there a way to run do this using plink/ssh? How to change default window background color in Windows 10? In Windows 7 and Windows XP it was very easy to change the default background color of all windows to whatever you want. Staring at white window backgrounds all day is hard on the eyes. Once changed, ALL windows of all apps would conform to the custom color as long as the apps allowed the windows bg to be invoked. So for example it worked great in Notepad and many other apps.   Then the geniuses at M$ decided that this feature was no longer needed in Windows 8, and removed it. There were some reg hacks, but nothing standard. I remember reading that the feature would be coming back in Windows 10, but I'm not finding this to be the case. The only [partial/broken] way I have found to be able to do this is to tweak the following registry keys:  [HKEY_CURRENT_USER\Control Panel\Colors] "Window"="227 221 191"  [HKEY_CURRENT_USER\Control Panel\Desktop\Colors] "Window"="227 221 191"   When I changed those keys to my chosen soothing color and rebooted, it worked ONE TIME. After every reboot thereafter, all the white backgrounds are back AND YET those registry keys still have my custom RGB codes. I really hate Microsoft right now, but that aside, is there any solid way to change windows 10 bg colors and make it stick?  Important: In Settings -> Personalization -> Colors, none of that changes windows backgrounds. Already tried.   I am using Windows 10 Enterprise Version 1511 Build 10586.3.  UPDATE: I rebooted again and the bg colors work correctly...but later in the day all the window bgcolors were back to white again. Windows 8.1 had the exact same bug. My conclusion is that the reg hack "works" but only intermittently. Is this simply a MS bug? Or is there a better answer/solution? What is a "double date"? Any way to change my review of suggested edit? I goofed and rejected a suggested edit, a vote that was actually directed at the previous edit that I was reviewing. As this is unfair to the user who posted the suggested edit in question, is there any way in which to change/cancel my reject? I was asked this question in an interview.  Lets say we have a correlation matrix of the form \begin{bmatrix}1&amp;0.6&amp;0.8\\0.6&amp;1&amp;\gamma\\0.8&amp;\gamma&amp;1\end{bmatrix}  I was asked to find the value of gamma, given this correlation matrix. I thought I could do something with the eigenvalues, since they should be all greater than or equal to 0.(Matrix should be positive semidefinite) - but I don't think this approach will yield the answer. I am missing a trick.  Could you please provide a hint to solve for the same? Using subcaption package but subfigures end up stacked rather than side by side I'm trying to put two jpegs side by side using the subcaption package, but the images are consistently stacking on top of each other rather than side by side. All the solutions I've found simply state that the pictures have to be small enough to actually be side by side but I've tried making them smaller, too small even and they stay stacked. My code looks like this:  \begin{figure}[H] \centering \begin{subfigure}{0.5\textwidth} \centering     \includegraphics[width=0.3\linewidth]{inclusion.jpg}     \caption{inclusions}     \label{fig:inclu} \end{subfigure}  \begin{subfigure}{0.5\textwidth} \centering     \includegraphics[width=0.3\linewidth]{deform}     \caption{grain deformation}     \label{fig:deform} \end{subfigure} \caption{filler text} \label{fig:manmade} \end{figure}   Help would be greatly appreciated. This came up to me while I was reading the question about Magical being using firearms in battle to raise their power (which I think I have a good answer for, but it's too long to fit in this question... and it would also be inappropriate).  Anyways, I was reading it and then the following thought came into my mind: If wizards decided to use guns on their battles (the ones agains Voldemort for instance), that would create that opening for much bigger battles than we see in the books (after all even a muggle can fire a gun, so lots of guns + the Imperio curse, and presto manifesto (is that racist? talking about wizards and all) you have yourself an army). Those kinds of battles, however, would most definitely not go unnoticed by the muggles - even though they wouldn't be able to link it to magic.  Well, that thought brought up my one and final question, which I bring forth to you guys. Is there any mention on how the Wizards and Witches viewed the two world wars (which had taken part by the time Harry got to Hogwarts, and which he had probably heard about in muggle school), and what was the Wizards' part in it? What about the cold war? Did the magical world even recognise the existence of weapons such as nukes, which could render all life on earth extinct?  EDIT  DVK has brought up an  regarding the connections between the Second World War and the wizarding world (more specifically, the wizard Grindelwald). Although it doesn't fully answer my question, it does help by showing that there was indeed some form of connection between the two world at the time. How to read high voltages on microcontroller? I'd like to delete a file from my Time Machine backups, but there seems to be no option to do so in the Big Sur version of Time Machine. I go to the Time Machine menu and select &quot;Enter Time Machine&quot;. Then I see the view with the stack of windows. I browse to a file and select it. Now I want to delete it so it doesn't exist and take up space in backups. There is no option to delete it - either the action menu in the toolbar, or the control-click context menu. How do I delete a file from Time Machine backups? There used to be a way to do this. (I'd take a screenshot, but the key shortcuts for screenshots don't work in Time Machine. Not sure if this is just a Big Sur thing or if that's always the case.) Update: I should mention I'm using APFS for my Time Machine volume. That seems to be relevant. Also, I contacted Apple support about deleting entire snapshots (slightly different goal than the one here in this question). They said you can't do it anymore. It seems like there's some bugs here, because I have a &quot;Move to Trash&quot; option if I control-click one of my backups. It seems to work initially but then the backup comes back.  I don't like losing this much control over my files. I may look for another backup solution. Do paths in Adobe Photoshop have to be closed? I am working to convert a png to a vector graphic.  I am outlining the image using the pen tool.  Photoshop insists that the pen tool produce closed loops in order for me to use the "Stroke path..." tool.  Why is this? How can I render an edge only mesh as solid lines? Upon answering the telephone, the person calling asks if Joan is available. If Joan is the person who answered the phone, should she say "This is her" or "This is she"? How can I retrieve \thepage (or detect a page change) from Lua in LuaTeX? I am writing (contributing to) a LuaLaTeX package where a Lua function is used to generate images that are inserted in the LaTeX document.   One piece of information we need is the current page number to determine if we're on an odd or even page (I know that this is not that trivial, and I know about some strategies beyond \thepage). We set a Lua variable when we're still in the LaTeX part, and so far this works pretty well.  However, now it turns out that the sequence of images we create may be distributed on several pages, and we would really like to reflect that because our images may behave differently on odd and even pages.  Basically what we have is a series of  tex.print('\\includegraphics{something}\\par')   statements, executed in a loop within one Lua function.  Now the question: is there any way to either directly detect a page change between two such graphics or repeatedly retrieve the current page within such a loop?  All the solutions I have found for determining current odd or even state are in LaTeX itself. I know how to use \directlua to retrieve a value for use in LaTeX, but is there a way to do the opposite - retrieve a LaTeX value from within LUa?  Edit: to respond to TeXnician's comment and answer: When I modify the example code so it produces repetitions of paragraphs it seems that the page counter won't get updated within one Lua chunk:  \documentclass{article}  \newcommand\printluapage{%     \directlua{for i = 1, 60 do tex.print(tex.count['c@page'])          tex.print([[\par]]) end} }  \begin{document} \printluapage  New command  \printluapage  New command  \printluapage \end{document}   The page number is only updated with each new call of \printluapage.
