This is a scenario set up for MCSA training in my homelab, not an enterprise environment.   I'm trying to make changes to add roles to a virtual machine (VM workstation) Server 2012 R2 (running in bridged mode, meaning it gets dynamic IP from physical default gateway dhcp server) from my main Server 2012 R2 physical server from Server Manager, All Servers.   I add the remote server, TESTSERVER1, via manage->add servers and it shows up as such in "All Servers":   Here are the error messages produced:   The main physical server, APOLLO has a static IP but the VM server is dynamic. This is a 255.255.255.0 subnet. This is a workgroup environment.  How can I gain access to TESTSERVER1 so I can make changes to it remotely. When I right click it, "add roles and features" and "restart server" are greyed out. I appreciate any insight, thank you.
I am trying cmd --> MMC --> Server Manager and then connecting to my Server 2012 no GUI  but i keep getting the following error The WinRM client cannot process the request  I am unable to upload images right now  This is not related to other post "How to Remote Manage Windows Server 2012 in Server Manager?" because title and description of that post is quite different from what i am asking
What sci-fi work first showed a weapon of galactic-scale mass destruction? Currently, I have two examples in my mind:   Halo (Halo video game series; 2001): Can destroy all sentient life within three galactic radii The Moment/ Eye of Discord/ Galaxy Eater (Doctor Who (2005) TV series; 2013): Can destroy entire galaxy within a moment   What sci-fi work first showed a weapon of galactic-scale mass destruction? We work heavily with serialization and having to specify Serializable tag on every object we use is kind of a burden. Especially when it's a 3rd-party class that we can't really change.  The question is: since Serializable is an empty interface and Java provides robust serialization once you add  implements Serializable - why didn't they make everything serializable and that's it?    What am I missing? General system specs for large scenes in blender What are the system requirements for working with complex geometry in Blender? Things like RAM, GPU, CPU etc.? Distribute objects optimaly So I've got a file with loads of simple objects. This will later be used to cut out these shapes out of plastic. So, using the material optimally is of outmost importance. I was wondering if there is any script or plugin that could automaticly arrange the objects within the artboard so they could fit best. The   echo one; echo two &gt; &gt;(cat); echo three;    command gives unexpected output.  I read this:  and many other articles about process substitution on the internet, but don't understand why it behaves this way.  Expected output:  one two three   Real output:  prompt$ echo one; echo two &gt; &gt;(cat); echo three; one three prompt$ two   Also, this two commands should be equivalent from my point of view, but they don't:  ##### first command - the pipe is used. prompt$ seq 1 5 | cat 1 2 3 4 5 ##### second command - the process substitution and redirection are used. prompt$ seq 1 5 &gt; &gt;(cat) prompt$ 1 2 3 4 5   Why I think, they should be the same? Because, both connects the seq output to the cat input through the anonymous pipe - .  Question: Why it behaves this way? Where is my error? The comprehensive answer is desired (with explanation of how the bash does it under the hood). Let $X$ be simply connected and let $ \tau $ be a cycle in $X$. If $ \tau(0)=\tau(1)=x_0$ and $\gamma $ is a path between $x\in X$ and $x_0$, is $\tau$ homologous to $ \gamma\tau\gamma^{-1} $?  I think it is, but I'm not sure about the proof. Can I use the fact that $ \gamma\tau\gamma^{-1} $ is homologous to $ \gamma+\tau+\gamma^{-1} $, where $+$ is the operation between 1-chains (that is abelian)? So I was writing up a simple binary tree in Python and came across [...]  I don't believe this to be related to the Ellipsis object, more it seems to have something to do with an infinity loop (due to Python's shallow copy?). The source of this infinity loop and why it doesn't get expanded while expanding when accessed is something I'm completely lost to, however   &gt;&gt;&gt; a [[[[[], [], 8, 3], [[], [], 3, 2], 6, 3], [], 1, 4], [[], [], -4, 2], 0, 0] &gt;&gt;&gt; Keys(a)#With a+b [0, 1, 6, 8, 3, -4] &gt;&gt;&gt; Keys(a)#With [a,b] [8, [...], [...], 3, [...], [...], 6, [...], [...], 1, [...], [...], -4, [...], [...], 0, [...], [...]] &gt;&gt;&gt; Keys(a)[1]#??

Bash: command not found What is port forwarding and what is it used for? There are a lot of questions on , but there doesn't seem to be one that clearly states what it is and what it's used for.

What is involved in moving over to Lightning Web Components? says:  SSH_ASKPASS    If  ssh needs a passphrase, it will read the passphrase from the    current terminal if it was run from a terminal.  If ssh does not    have  a  terminal associated with it but DISPLAY and SSH_ASKPASS    are set, it will execute the program  specified  by  SSH_ASKPASS    and open an X11 window to read the passphrase.   I'd like SSH to use an askpass program even if it was run from a terminal.  On occasion, I have to connect to servers, where there's some delay in showing a password prompt (maybe due to network issues, maybe due to attempted reverse DNS lookups, …). I get annoyed and switch to something else, and forget about the attempted connection. (Insert joke about attention span of a goldfish.) When I finally get back to it, the prompt's timed out and even a correct password would just result in a closed connection.  Keys would be one solution, but not every system I use has my usual SSH keys. However, I usually use Ubuntu systems, and Ubuntu has an SSH askpass program installed by default.  If an askpass window popped up, however, I'd be immediately aware of it. That's a good enough compromise for me, if only I can get it to work. Necromancy In Harry Potter How is Necromancy accomplished in the Harry Potter universe?  I thought that people cannot be raised from the dead in Harry Potter.

All,  I would like to cook spare ribs to a fall-off-the-bone consistency.  I don't have access to a grill.  I know how to do that with pork shoulders (dry rubbed, then uncovered in the oven at low heat for 6-8hrs), but spare ribs are a different type of animal.  They are individually smaller pieces (my ribs are sawed in chunks), and they are fairly fatty, with a big bone.  What should I do?  Should I pan-sear them first, do I need some liquid in the dish?  Should I cover them?

I have scripts calling other script files but I need to get the filepath of the file that is currently running within the process.   For example, let's say I have three files. Using :   script_1.py calls script_2.py.  In turn, script_2.py calls script_3.py.    How can I get the file name and path of script_3.py, from code within script_3.py, without having to pass that information as arguments from script_2.py?  (Executing os.getcwd() returns the original starting script's filepath not the current file's.)
