How do I install python 3.5.2?
Is it possible to install Python 3.x in 14.04 LTS, or upgrade from Python 2.7.6 to 2.7.8?
Sending the output from 'dd' to awk/sed/grep I'm trying to approximate the computer's write speed using dd:  dd if=/dev/urandom of=/dev/null bs=1K count=10000   which gives the following output  10000+0 records in 10000+0 records out 10240000 bytes (10 MB) copied, 0.746313 s, 13.7 MB/s   How can I get the '13.7 MB/s' into a bash variable? I've tried piping the output from dd to progs like awk, sed and grep to no avail.  Ultimately, I'm calling this via os.system(...) from within a python script. If anyone knows of a more direct way to get a similar result inside python I'd be interested in that also. I'm trying to predict how long a file copy will take, based on the file size.  Any help would be greatly appreciated. I would like to be able to write a Java class in one package which can access non-public methods of a class in another package without having to make it a subclass of the other class. Is this possible? Which one is correct to say: "It's me" or "It's I"? Is there a shorter alternative for "Enjoy your meal"? The French have "Bon appetit".   In Belgium and the Netherlands we have "Smakelijk".  Is there a short way to wish someone a good meal in English? When visiting my profile on the mobile app, my hat scrolls with the page:    It doesn't stay linked to my icon at the top. I'm on an iPhone 6+ running iOS 9.2 and version 1.4.1 of the SE app. If $f:\mathbb{R}\to\mathbb{R}$ is continuous and $$\lim_{x\to\infty}f(x)=\lim_{x\to-\infty}f(x)=\infty$$  Prove that $f$ has a minimum on $\mathbb{R}$; that is, there is an $x_m\in\mathbb{R}$ such that $$f(x_m)=\inf_{x\in\mathbb{R}}f(x)&lt;\infty$$  I think the best approach would be to prove the existence of a lower bound, that is $\exists M\in\mathbb{R}:M&lt;f(x),\forall x\in\mathbb{R}$, but I don't know how to do this. I am probably supposed to use the extreme value theorem or the intermediate value theorem, but I don't know how to do that. Why won't Amanita move in and settle down?

Set Xorg to use only part of the screen How to block specific notifications from an app? A certain app I use gives me crucial notifications that I need, but also notifies me almost daily that over 80% of my RAM is used. I would like to allow this app to send me all notifications except those that contain the string "80% of your RAM" in the text of the notification.  Obviously, there is no way to filter a certain app's notifications in stock Android (other than blocking all of a certain app's notifications, but that's not what I want!), but is there a way that I can block notifications if they contain a certain string of text?

When is the image of a linear operator (between Banach spaces) closed? Let $T: X \longrightarrow Y$ be a continuous linear map between two Banach spaces.  When is $\operatorname{Ran}(T)$ a closed subspace?  What theorems are there?   Thanks :) Proof of a basic $AC_\omega$ equivalence On  it is mentioned that "...  in order to prove that every accumulation point $x$ of a set $S\subseteq \mathbf R$ is the limit of some sequence of elements of $S\setminus \{x\}$, one uses (a weak form of) the axiom of countable choice. When formulated for accumulation points of arbitrary metric spaces, the statement becomes equivalent to $AC_\omega$. ..."  I have Herrlich's paper "Choice principles in elementary topology and analysis" where in theorem 2.4. it is stated that these are indeed equivalent. Then I looked up the reference he quotes, [4], which are Bentley H.L., Herrlich H., Countable choice and pseudometric spaces which does not contain the proof and  does also not contain the proof, hence my question:   Where can I see a proof of      "if $S$ is a set in a metric space $X$ with accumulation point $s$   then there exists a sequence $s_n$ in $S$ converging to $s$"   $\implies$ $AC_\omega$   ? (the other implication is clear to me). Thanks. Providing command key-value arguments with commas in value When using commands that allow using key-value pairs, how can one provide an argument value that has commas in it? As an example, say I'm using the \newacronym command from the glossaries package as below:  \newacronym[firstplural = Alphas, Bravos, and Charlies (ABCs), plural = ABCs]{ABC}{ABC}{Alpha, Bravo, Charlie}   Unfortunately, the comma is used to separate key-value pairs so the Bravos, and Charlies (ABCs) portion doesn't get parsed correctly. Is there a way to overcome this? How to get from Gatwick airport to Paddington? What's the most straightforward way to get from Gatwick airport to Paddington station in London using public transport?   I'm mostly interested in travel time &amp; general smoothness of the trip (e.g. buying just one ticket for the whole trip would be nice). Price is a secondary concern.
