Prior to Ubuntu 18.04, the compress dialog window listed a dozen file formats to choose from:    In the new version, the dialog window offers only 3 options:    This is somewhat limited in my opinion. I am used to compress my packages in the tar.gz format, and I like have all of them with the same extension.   I know one can manually open the archive manager window, drag-and-drop a directory into it and then create an archive to get a tar.gz package. Alternatively, I can use the terminal. But both of these approaches are somewhat sub-optimal and less immediate than the previous one.  Q: is there any way to restore the old compress dialog window in Ubuntu 18.04?
In Ubuntu 17.10 ubuntu upgraded Nautilus (File Browser) to version 3.26.0. New nautilus is not using file-roller anymore, it has  to an integrated compression mechanism.     This makes it complicated to create encrypted archives and/or different types compression archives that file-roller does provide.  How to make nautilus use file-roller as before?  Related question:

At first glance, hyperref provides two similar macros to put links between parts of my document: \hyperlink{target}{text} and \hyperref[target]{text}. You might notice their slightly different syntax. What really interests me is their different working mechanics. I will illustrate this by the following example: \documentclass{article}  \usepackage{pdfpages} \usepackage[]{hyperref} \usepackage{mwe}  \begin{document}  \section{Section Heading} \label{sectionheading}  \includepdf[link=true, linkname=pdfpage]{example-image}   Link to section works with \hyperref[sectionheading]{hyperref} and with \hyperlink{sectionheading}{hyperlink} (but with slightly different targets on the page).  Link to pdf works with \hyperlink{pdfpage.1}{hyperlink} but not with \hyperref[pdfpage.1]{hyperref} (and not this way, either: \hyperref[pdfpage]{hyperref}).  \end{document}  To link to the labeled section heading, I may use both commands. While \hyperref directs my pdf viewer directly to the linked section, \hyperlink directs me somewhere slightly different, so I can see more context. To link to the \includepdf of pdfpages however, I may only use \hyperlink. \hyperref does not work at all. I suspect this is because of a subtle difference in their working mechanisms. While checking the aux file, I found a line \newlabel{sectionheading}{{1}{1}{Section Heading}{section.1}{}} which \hyperref seems to use as a target. However, I did not find any similar target for the included pdf. My question: I suspect, I understand the workings of \label and \ref very well. \hyperref seems to work quite similarly with the added clickability. Could you please explain to me how \hyperlink does work differently and how it is implemented? E.g. what mechanics explain the difference when clicked on the link and where and how are the link targets stored in the first place? style=apa causes bibliography to fail Dial PPPoE connection on Windows startup Is there a way to automatically dial a PPPoE connection on startup? In Mac OS X, this is done automatically after login. It was also possible in Windows XP: when creating a new connection, it also created a shortcut to it on the desktop. Adding it to the startup folder and setting it to not prompt for credentials solved the problem.  But in Vista and Windows 7, there are no shortcuts to the newly created connections, so I can't do the same thing here. Is there any other way to do this? What the difference is here?

How to turn a ruled pattern into a multivariable function Let be $u,v\in\mathbb{R}^n$, then $\det(I+uv^\intercal)=1+v^\intercal u $ where $I$ denotes the identity matrix of order $n$. How to prove this?   what I did:   let be $A=\{n\in\mathbb{N}: \forall u,v \in \mathbb{R^n}, \det(I+uv^\intercal)\neq1+v^\intercal u  \} $, and suppose $A\neq \varnothing $, then for the well-orderer-principle there exists $n_0\in A$ such $n_0\leq n,\;\forall n\in A$. since $1\notin A,\; n_0\neq 1 \rightarrow n_0-1\in\mathbb{N}\setminus A  $ so: $$\forall u,v\in\mathbb{R^{n_0-1}}: \det(I+uv^\intercal)=1+v^\intercal u $$ Then, let be $u,v\in\mathbb{R}^{n_0}$, so $$\det(I+uv^\intercal)= \displaystyle\sum_{j=1}^{n_0}(-)^{1+j}a_{1j}\det(A_{1j})$$ where $a_{ij}=\begin{cases} u_iv_j+1 &amp; i=j \\ u_iv_j &amp; i\neq j \end{cases}$, and $A_{1j}$ is the  submatrix of $I+uv^\intercal$ that results deleting the i-file and j-column. Then I try to open the term for $j=1$ and try to use the relation for the new matrix of $n_0-1$ order with the determinant because it holds the same form but I have other terms which difficult me the work.

If a charge travels in a circle it must accelerate, thereby producing EM.  However, a wire in a circular loop is analogous to many charges moving in a circle.

Book with travellers, alien artefacts and age reversal Looking for the title of a book I read about 5 years ago though I believe the book was a lot older.  Essentially the main male character was on a task and was travelling with a group of people. The mode of transport if I recall was a boat and they were on a remote planet travelling via a river. One of the group was a father to a young female infant. There's a reference to alien artefact/temple that essentially reverse aged a female scientist (the baby) a day at a time and the father is trying to undo it. Also a line I remember is the father used to say see you later alligator and the daughter will reply that awhile crocodile until a day where she forgot.  Another fellow traveller was a pilgrim and his male disciple. There are several other male and female travellers all had different reasons to travel to that location.  The aliens was located within the temple (time locked?) Were invisible to humans. Killed any that entered. Got the impression that they were quadpeds with organic blades/razors that cut people.  I believe the book may be part of a series. The male author though I don't recall the name, has written other works that have received awards. The book or series may have received one too. Which is probably why I decided to read it in the first place.  Question never asked anywhere else. I am from Australia, book was a paper copy bought locally.

Special event cards and timing I have video tutorials that I want to show in my presentation with beamer class. I don't want the video files get embedded to the PDF because they will make the PDF size very very huge.
