I want to be a Telnet Server, but i couldn't troubleshooting that why other computer on my LAN couldn't connect to me. I went these same steps on other computers but there were no problems to connect them and i can telnet to them. 1) i turned Telnet Client and Telnet Server features from "Control Panel\All Control Panel Items\Programs and Features" 2) then i enabled TELNET service from Services.msc and set that to Automatic. 3) also i enabled Telnet Server option from "Control Panel\All Control Panel Items\Firewal\Advanced settings (Inbound Rules)" and allowed the connection. 4) so i started Telnet Server service from CMD using "net start telnet"  then i tried to connect my Telnet Server from other LAN Computers. but it said:   Connecting To 192.168.1.103...Could not open connection to the host, on port 23:  Connect failed   How can i Fix this problem ?  I'm using Windows 7 and Avast! Anti-virus and Avast! internet security.  note: I did these same steps on another LAN computers , so i could connect to them.

Ubuntu copy dialogue stops at the last moment for a long time Whenever I try and copy a file to an USB flash disk, the progress bar runs till the end very fast and stops for an indeterminable time before it is complete.  Is there an issue with ubuntu or my flash disk is what I am not able to figure out. All I want is a realistic copy dialogue Assuming there are 5 items in the settings file (MySetting1 to MySetting5), why does PropertyValues have 0 items while Properties has the correct number?   Console.WriteLine( Properties.Settings.Default.PropertyValues.Count); // Displays 0 Console.WriteLine( Properties.Settings.Default.Properties.Count);     // Displays 5 Proof that an integral domain that is a finite-dimensional $F$-vector space is in fact a field Draw Lewis structures like a book I want to draw a Lewis structure as in the picture. I tried to do with chemfig but does not perform the separation of the points and a minus in the superscript. Prove Equivalence Relation in G Hei, guys!  I'm having some trouble with the next problem:  Let $A$ and $B$ be subgroups of $G$. Show that $\sim$ is an equivalence relation when it is defined as follows: $g\sim g'\Leftrightarrow g' = agb$ for some $a$ from $A$, $b$ from $B$.  Should I prove this is valid for any a and b? It says for some elements a and b. But I might as well take the unit element.   Could you give me a clue on how to solve it?  Cheers! How do I repair my weapons and armor? Why GCP Kubernetes Node host location for europe-north1 seems to be in US? I am new to both Google Cloud Platform and K8s. I have launched Kubernetes cluster in GCP and chosen europe-north1 as the region (europe-north1-a as the zone).   When I try to run my application on this cluster it fails because it expects the application to run in EU region. I added IP and Geo check (using GeoLite database () and AWS IP check tool ()) into my application and they tell me that the host is located in US.  Have I perhaps missed some GCP/K8s configuration option or is this because the europe-north1 region is still quite new and the IP addresses do not correctly show that they are located in EU? In which case I should direct this question to Google? What is the mass density distribution of an electron? In PHP you can do:  print_r($var) or vardump($var)   which prints "human-readible" information about variable.  Is there equivalent functions / helpers for those in Ruby / Rails ? My images are blurry! Why isn't WPF's SnapsToDevicePixels working? I'm using some Images in my WPF applcation.  XAML:  &lt;Image Name="ImageOrderedList"        Source="images/OrderedList.png"        ToolTip="Ordered List"        Margin="0,0,5,5"        Width="20"        Height="20"        SnapsToDevicePixels="True"        MouseUp="Image_MouseUp"        MouseEnter="Image_MouseEnter"        MouseLeave="Image_MouseLeave" /&gt;   But, they appear fuzzy.

Running programs in the background from terminal Reset the password in Ubuntu / Linux Bash in Windows I have installed Linux Bash on Windows 10 (available from Microsoft), but I've forgotten my password.  I've searched for a solution but I only find suggestions that involve doing something before the system boots, like accessing recovery mode, but that will not work in this case as this Ubuntu is just an application within a Windows system and doesn't have its own boot process.  How can I reset my password? What's a big-vocabulary word for someone with a big vocabulary? What's a big-vocabulary word for someone with a big vocabulary?

IBus methods do not show up in text entry settings I installed both Korean and Japanese using the Language Support window, and expected Korean (Hangul) and Japanese (Anthy) to show up in the input sources for Text Entry Settings (having both packages installed). However, neither shows up. Linear regression prediction interval If the best linear approximation (using least squares) of my data points is the line $y=mx+b$, how can I calculate the approximation error? If I compute standard deviation of differences between observations and predictions $e_i=real(x_i)-(mx_i+b)$, can I later say that a real (but not observed) value $y_r=real(x_0)$ belongs to the interval $[y_p-\sigma, y_p+\sigma]$ ($y_p=mx_0+b$) with probability ~68%, assuming normal distribution?  To clarify:  I made observations regarding a function $f(x)$ by evaluating it a some points $x_i$. I fit these observations to a line $l(x)=mx+b$. For $x_0$ that I did not observe, I'd like to know how big can $f(x_0)-l(x_0)$  be. Using the method above, is it correct to say that $f(x_0) \in [l(x_0)-\sigma, l(x_0)+\sigma]$ with prob. ~68%? OEM license activation for Windows 10 Home VirtualBox guest, on Ubuntu host Context Three years ago my company got me a Lenovo T550 with Windows 10 Home installed on it (my understanding is that this is called &quot;OEM&quot;). I immediately erased everything to install Ubuntu on it. Unfortunately from now on I will need to use Windows 10 a few times a week for legacy reasons, but my main work is still on Ubuntu, so I am thinking of running Windows 10 within VirtualBox within Ubuntu. Lenovo recommendation Lenovo told me that my Windows Home license is somehow linked to my hardware (firmware?) and that Windows will automatically find this out. They pointed me to :  The installation of Microsoft Windows Server 2008,2008 R2 SP1, 2012, and 2012 R2 from Lenovo OEM media to such a virtual machine will fail until the virtual BIOS has been updated to include this information. setVMBIOS.exe performs this function for servers using Microsoft Hyper-V technology. Consult your hypervisor vendor for information on how to perform this function on other hypervisors. [...] The fix resolves this issue by adding Lenovo information to the virtual BIOS.  Note: That page does not mention Windows 10 Home, but I guess the same applies? VirtualBox How to apply Lenovo's recommendation to VirtualBox?
