How do I remove a malformed line from my sources.list? View revision history on mobile site It looks like it's currently not possible to view the revision history of a post from the mobile site. I think it would be a lot simpler than loading the desktop site on a phone just to get the revision history. It is a well known fact that Alex is more soft-spoken than (she/her).    Why would "her" be wrong? Why must the sentence end with "she"? Problem installing .deb in Software Install Ubuntu 20.04 I tried to install some .deb files in Ubuntu 20.04 from GitHub and other internet sources, but when I open it with Software Install it gives me  problem (Failed to install file: not supported). The only way for me to install them is to go to the downloaded file and do sudo dpkg -i file.deb. Can anyone help? I don't know what to do and I don't want to use the terminal every time. Any help would be appreciated, thanks EDIT: that's NOT a problem with .deb in Ubuntu, it is a problem with Software install. I can install every .deb through the terminal but not with Software install, and Ubuntu suggests to install .deb with Software install. That's not a dependencies problem or anything similar, that's an issue with installing .deb WITH Software install and I would like to know how I can fix Software installer Reading a binary file and using Response.BinaryWrite() parskip package, keep the indents That may be a stupid question but is there a way to keep the indent while using the parskip package? I use parskip to keep spacing between my paragraphs while leaving the table of contents and lists intacts but I would like to keep the indents in my text.  Code 1 :  \usepackage{parskip}  \tableofcontents  \section{Section 1} \subsection{Sub 1}  Paragraph 1  Paragraph 2   Code 2  \setlength{\parskip}{10pt}  \tableofcontents  \section{Section 1} \subsection{Sub 1}  Paragraph 1  Paragraph 2   Basically I want the aspect of the table of contents (and possible lists) from the code 1 while keeping the indent like in the code 2. The package parskip works great but I just don't like that it deletes the indents and I'd like to find a way to prevent it from doing that.   Thank you. PostgreSQL create line from points For a specific package, can I find out why it is installed?  So, can I see or it's manually installed, or that it is installed as a dependency of another package? Or that it is installed as part of the distro? In my Master thesis, I used this:  \begin{itemize}[label=\ding{167}] \item Access Windows XM from Ubuntu Server \item List the directories contents of Windows XP \end{itemize}   The output is:  My question: must I avoid the use of  such beautiful things when writing my thesis or is it a normal thing to do ?

How do we define capillary number in 2D (two dimensions) In 3D the capillary number $Ca$ is defined as: $$Ca=\frac{\nu \rho U}{\gamma}$$ where $\nu$ is the kinematic viscosity ($m^2/s$), $U$ is the velocity ($m/s$)and $\gamma$ is the interfacial tension ($N/m$) and $\rho$ is the density in $kg/m^3$ . However in 2D I will have $\rho$ in units of $kg/m^2$ (2D simulation), so how to find capillary number? bcmwl-kernel-source broken on kernel: 5.8.0-34-generic How does a magnet work?

Circuitikz symbols in TikZ circuit library Some time ago, I asked about . wh1t3 wrote: "However, as far as I know there is nothing the circuitikz package does that the TikZ circuit library can't."  So if it is true that the tikz library is more powerful, how do I get all the symbols described in the  using the TikZ circuit library?  Especially I am missing the symbols for ammeters and voltmeters. Proving $\gcd \left(\frac{a}{\gcd (a,b)},\frac{b}{\gcd (a,b)}\right)=1$ How would you go about proving that $$\gcd \left(\frac{a}{\gcd (a,b)},\frac{b}{\gcd (a,b)}\right)=1$$  for any two integers $a$ and $b$?  Intuitively it is true because when you divide $a$ and $b$ by $\gcd(a,b)$ you cancel out any common factors between them resulting in them becoming coprime. However, how would you prove this rigorously and mathematically? Blending colors in photoshop and illustrator I am working on a print for my wall and I am trying to create something like this:      I have already created the letters in Illustrator and now I am adding the colors in Illustrator and then exporting everything to Photoshop and then using the liquify tool to blend the colors to create a similar effect. I also used the healing patch tool to blend in the hard edges.  Is that the right way of doing it? Or is there another way?
