Is there a way to edit/tweak the regional settings?
How can I customize a system locale?
Prime number expressible as $2^2+3^3+5^5+7^7+11^{11}+\cdots$ To prevent overfitting people people add a regularization term (proportional to the squared sum of the parameters of the model) with a regularization parameter $\lambda$ to the cost function of linear regression. Is this parameter $\lambda$ the same as a lagrange multiplier? So is regularization the same as the method of lagrange multiplier? Or how are these methods connected? Drag and drop not working inside Nautilus on Ubuntu 17.10 Associativty of smash product on compact spaces Let $Y,Z$ be compact or $X,Z$ locally compact. Then the canonical bijection    $$ (X \wedge Y) \wedge Z \rightarrow X \wedge (Y \wedge Z) $$    is a homeomoprhism.    I can prove the case when $X,Z$ are locally compact using exponential law. But I don't see how one approaches the case when $Y,Z$ compact. Hints? Where to find or how to make a frame like  below picture with optional width and height? Proving the convergence of $\sum\limits_{n=1}^{\infty}\frac{1}{1+z^n}$ for $|z| > 1$ Outline radius? Every non-empty subset of the integers which is bounded above has a largest element. I was reading a proof about every non-empty subset of the integers which is bounded above has a largest element, but i have troubles in one step. Here is the proof:  Since $S$ is a non-empty subset of $\mathbb{Z}$(hence $\mathbb{R}$) which is bounded above, by the supremum property $sup S$ exists. Let $w=supS$, then we have to show that $w \in S$, so we suppose $w \notin S$, then we have $w-1&lt;w$, then exists $m\in S$ such that $w-1&lt;m&lt;w$(here is my problem, why can we take $m\in S$ such that happens? we are in $\mathbb{Z}$, so that does not happens). Then he takes $n\in S$ such that $w-1&lt;m&lt;n&lt;w$. The inequality $n&lt;w$ implies that $-w&lt;-n$, and $w-1&lt;m$, if we add up both inequalities we have $-1&lt;m-n$ implies $n-m&lt;1$, then $0&lt;n-m&lt;1$ which is a contradiction because there are no integers between $0$ and $1$ Can anybody explains me if that step is right?? How can I prove this if there is a problem with that step? Thanks! I accidentally installed some USB drivers to my Windows 7 system, they were the wrong ones and now my keyboard and mouse won't work. A system restore would get rid of them, but obviously I can't control my computer to make that happen.  Keyboard and mouse still work before windows has loaded, in the BIOS and boot system, so can I do anything from there? I've already tried booting into another OS, accessing my windows filesystem and deleting the Program Files entry, but it didnt work so they must go deeper than that. Or could i launch it from a remote machine? I've got some VNC server insalled so if i could get that running that could work. Making leaflet control open by default I'm using leaflet to display a map.  I have a control section that I'd like to be open by default, but I can't find a way to do it through the . Is there a way to do this? How do I add a repository from behind a proxy? I've a problem at the office. We're behind a proxy (which is set and applied at ubuntu proxy settings) and when I try to add a repository from terminal, I get:      Error reading --some url here--: urlopen error [Errno 113] No route to host   I've tried with   Launchpad-getkeys script.

Does anyone know if I could solve this problem in any way? Thanks I'm a teacher and I teach at/in school OR at/in a school There are a lot of posts on this topic, but I can't find any answers to my question.  I came across the following two definitions of 'school':        [uncountable] (used without the or a) the process of learning in a   school; the time during your life when you go to a school (British   English)   [uncountable] (used without the or a) the time during the day when   children are working in a school      Source:   I know there are better ways to convey the message, but which sentence would a teacher utter if he was a school teacher teaching students, adults, etc.? What about a janitor, director, and secretary?     I teach at/in school OR I teach at/in a school   The above definitions concern students, and not working individuals like teachers or janitors.  I would appreciate if you also stated whether you're American, Canadian, British, etc. Word for something sad and funny at the same time What's a word for conflicting emotions that are felt at the same time? For example, loneliness, sadness, happiness, being content but also feeling as if something isn't right?  To sum up: What's a word for something that is sad and funny at the same time? Matlab Recursion Loop How can I make all text the same font size (normal text, footnotes, acknowledgements etc.)? I have to submit a manuscript to a journal, and I just realized that they want every single part of the paper to be in 12 pt font. This includes tables text, footnotes, acknowledgements etc. Is there a way to force all text to be the same size? How to open a file manager of the current directory in the terminal? When I work in terminal, sometimes I want to open the current directory in a GUI file manager. And then to click the items in the window to run the application. How can I do this? How can I install the most used plugins like flash player and mp3 in Ubuntu? Is a match forfeited if a player refuses to leave after being sent off? Possibly two questions in here: Are these sentence constructions logical, and if they are, why are they different?     I swam across the Ocmulgee River.   I swam across the Pacific Ocean.   I swam across the Red Sea.   I swam across Lake Winnipeg.   I can't think of a way of phrasing the lake example while using an article with a proper noun. I thought at first it was because Lake Winnipeg is different; it's generic portion (the "Lake") comes first and the name of that body comes second, but I swam across Falls Lake is the same.   Yet the sentence I swam across the lake sounds right to me. ...Why? I've been using Ubuntu for a few years now, but I just installed Version 16.04, and I've been having a lot of issues. I'm not a command line expert, but I tried to install some software last night, and it is creating issues (and also not working properly).   When I run sudo apt-get -f install, I see the following message:  Reading package lists... Done Building dependency tree        Reading state information... Done Correcting dependencies...
