Edit : other answer talked about change the title of the terminal, not a tab, but effectively they answer to my question too. Everything is great.  I'm a newbie and I wonder how give a specific name to a terminal tab instance ?  Here an instance of my question :     Currently I have just few knowledge in Ubuntu system. Thanks
When I was using ubuntu 14.04, it's easy to set title. Just press F2 or move mouse to top menu. But there is no menu on ubuntu 16.04 and press F2 can't change the title. What should I do?
How do you pluralize the acronym "POC" ("proof of concept")? Possible Duplicate:          What's the plural form of the acronym , short for proof of concept?     ...for his contributions to many POCs   or      ...for his contributions to many POC      is not a duplicate as it is focused on cases like "ATMs" where the expanded form "automated teller machines" ends in a noun with a regular plural form ending in "s." In "proof of concept," the noun is in the middle of the abbreviated phrase. If we pluralize the uncontracted phrase, we get "proofs of concept," which has an "s" in the middle rather than at the end. It's unclear from the linked answers how abbreviations with this structure should be pluralized. (POC, POCs, PsOC?) Prove that the additive groups $\mathbb{R}$ and $\mathbb{Q}$ are not isomorphic. Is there a better (or other) way(s) to prove the following statement? Also, the same argument works for multiplicative groups $\mathbb{R}-\{0\}$ and $\mathbb{Q}-\{0\}$, right?       Problem Prove that the additive groups $\mathbb{R}$ and $\mathbb{Q}$ are not isomorphic.   Solution By cantor's diagonal argument, there is no possible bijection between $\mathbb{Q}$ and $\mathbb{R}$. Since an isomorphism needs to be a bijection, there is no possible isomorphism between the additive groups $\mathbb{R}$ and $\mathbb{Q}$.

It would be super useful if Stack Exchange could support this syntax.    By extension, this syntax also allow you to specify the source language right after the opening ```:  ```js // some code // another line of code ```   …which would then enable syntax highlighting for that specific language. Although it’s interesting metadata, I don’t think this feature is needed on Stack Overflow, as the syntax highlighting library works pretty well for various languages.  So, even if you would allow this syntax but ignore the ```language, this would greatly improve my productivity on Stack Exchange.  What do you think?

The Gmail sidebar displays the list of our labels (or some of them, according to settings). Next to every label name there is a number showing how many unread messages we have for that label.  Is there a way to display also the total number of messages for each label?  Example:  [to answer] (0/36) [to do] (0/55) [waiting answer] (0/7) cooking (2/48) family (6/352) friends (1/1828) website (2/412) work (12/12801) How did Montague Apparate into the Hogwarts bathroom? In year 5, Fred and George jam Montague into the Vanishing Cabinet. He's found weeks later in a toilet.      ‘He never managed to get all the words out,’ said Fred, ‘due to   the fact that we forced him head-first into that Vanishing Cabinet   on the first floor.’      […]      ‘They’ve found Montague, sir, he’s turned up jammed inside a toilet   on the fourth floor.’   ‘How did he get in there?’ demanded Snape.   ‘I don’t know, sir, he’s a bit confused.’   In year 6 Malfoy expands on that.      ‘I had to mend that broken Vanishing Cabinet that no one’s used for years. The one Montague got lost in last year.’      […]      ‘The other’s in Borgin and Burkes,’ said Malfoy, ‘and they make a kind of passage between them. Montague told me that when he was stuck in the Hogwarts one, he was trapped in limbo but sometimes he could hear what was going on at school, and sometimes what was going on in the shop, as if the Cabinet was travelling between them, but he couldn't make anyone hear him ... in the end he managed to Apparate out, even though he’d never passed his test. He nearly died doing it.   What happened here? Did he Apparate out into Hogwarts, Apparate into Borgin and Burkes and somehow wander back to Hogwarts and get stuck into a toilet? Tiny white very hard cell bug! Please help to identify! I found these bugs walking on the floor/ wall and on my laptop.  And unfortunately I think they could be in my bed, too, since I bring my laptop to bed sometimes.   I live in a big city in the Netherlands without pets. My house has humidity issues.  I have noticed that the bugs are very tough to exterminate; meaning that when trying to squeeze them it really needs a lot of effort for their size. Their size is about 1 - 2 mm and their color is whitish.    Please note that my lightbulb is having a yellow color.so it makes it look darker than normal. It's more white than looks in the picture          This is a pic of it walking on my screen... Passing directly an array initializer to a method parameter doesn't work You can't see the question owner's special color Lat/Long co-ordinates are not plotting onto EPSG:3857 OSM basemap correctly Excuse me if this is a stupid question, but I've honestly tried to find the answer in a few threads here on SE, and I cannot seem to follow the suggested steps correctly.    Project is in  (WGS 84 / Pseudo-Mercator) BaseMap (OpenStreetMap) layer is set to EPSG:3857 Vector data has been imported from CSV, and has Lat/Long coordinates, set to EPSG:3857.    The layer appears right in the middle of the map, around 0,0 obviously.   Why is this, what am I doing wrong? How do I prevent "Read more: www.site.com" from being injected with non-Tynt JavaScript into copy-paste actions? There are many sites that insert something like "Read more: www.site.com" into your clipboard when you copy text in your browser.  I find this abominable.  A google search reveals   to stop this if the website happens to be using the service  (by just blocking the Tynt domain), but many websites use home-grown JavaScript.  Is there a general way to block this behavior besides just turning off JavaScript?   I use Chrome but I am interested in all solutions.  EDIT: To be clear, I want to be able to keep the rest of the JavaScript functionality for these websites, since many will break without it.  EDIT #2: Here are two example websites which continue to harass me despite my use of a Tynt blocker:  |   Here are two   and two   which explain ways to implement this shady practice manually without Tynt.  Here is a  describing how hard this turns out to be to block reliably.  Here is the  I could find (March 2013) which offers suggestions on how to block this in Chrome using AdBlock, but it didn't work for me. When using find, how do I return the file name and the line number when searching for a string? I manage to return the file name in one command and the line numbers with another one, but I can't seem to combine them.  File names: find . -type f -exec grep -l 'string to search' {} \;  Line numbers: find . -type f -exec grep -n 'string to search' {} \; How can I remove Amazon search results from the dash or disable the feature? How can I disable Amazon search results in the Dash? Meaning of Simplify's tolerance parameter The standard parameters of Douglas-Peucker's simplify algorithm are geometry and tolerance (e.g  in PostGIS). What's the meaning of the tolerance parameter? I know that the bigger the value, the coarser the geometry will be. But does the number has any unit or it is just arbitrary? $\mbox{rank}(A)=1$ implies $\det(A+I)=\mbox{trace}(A)+1$ This problem comes from exercise from my lecturer  Let $A$ be a square matrix such that $\mbox{rank}(A)=1$. Prove that $\det(A+I)=\mbox{trace}(A)+1$.  ($I$ is the identy matrix)  I usually haven't any idea in solving linear algebra problem. Enumerate after \label I have the following code:  \usepackage{hyperref} \newtheorem{thm}{Theorem}  \begin{thm} \label{mythm}    \begin{enumerate}       \item     \end{enumerate} \end{thm}  \ref{mythm}   The ref prints the right number. However, when I click on it, it will lead me to a wrong page (basically, to the beginning of the document).  pdflatex also has some warning.  If I add $ $ between \begin{thm} and \begin{enumerate}, the problem disappears, but now, the enumeration starts a new line.  Is there any way to fix this? About embryonic and genetic evidence of evolution? My question here is about evidence for evolution from Embryology and from Genetics.  Mammals do have similar Embryos, but is it the case that for each species there is an embryonic development that occurs in earlier species, has such relationship been observed? What I mean for example if we generally conceive of having species$Sp_1,Sp_2,...,Sp_n$ where each $ Sp_{i+1}$ being evolved from $Sp_i,$ then is it the case that the embryonic development stages of $ Sp_{i+1}$ contains some of the embryonic development stages of all of its ancestor species.  Similar question to 1 but regarding Genetics, is it the case that every species has a genetic thumbprint of its ancestors that lie there in the non-functional sections of its DNA, i.e. is it the case that all the genetic history of our evolution is recorded in the non-functional section of our DNA. So do human DNA have some portions of the DNA of some dinosaurs for example?
