So from what I remember it was on cable TV. The main hero was a TV actor zapped to a alien planet. It had a evil overlord with a virgin priestesses. She wants to get laid but he refuses because the next priestesses is only three. Regardless it's a parody things include a man who was maimed by the evil overlord wants revenge the hero eventually screws the virgin priestesses it cuts to scenes of a train going into a tunnel and a volcano erupting. Does changing your Compute Device, change all computes of Blender? So, I have recently moved from using Blender, on my family's Nettop PC, to my personal, gaming PC. And with this move, came to option to use CUDA instead of CPU.  Which leaves the question, if I move to CUDA, does that change all computing, for like physics baking, or only for rendering?  Just a nooby question that I wanted to know, and yes, I know you can specify GPU rendering separately. I can't open google-related sites I'm  getting timeout errors on google-related sites. If I try to open google.com, gmail.com, etc, it will keep displaying the "waiting reply" on the browser bottom, and the page won't open. If I am browsing another site that includes, say, www.google-analytics.com, ajax.googleapis.com, google fonts, etc, then it start loading, displaying a "connecting to [google-related site]" on the browser bottom, and stall at that point for a long time.  I can browse other sites fine and they load quickly. I can ping the domains with 0% loss and &lt;100ms times. I can ping 8.8.8.8, I am not behind a proxy, there is nothing on my hosts file, I am not at work or in a networked environment: it is a home network behind a router. I connect using wifi (I am too distant to use wired).   Other users on the same network don't have the issue. I can both ping and browse the sites. I have pinged ajax.googleapis.com from my android and my other laptop, and they return the same IP than on this laptop. They also share the same external IP address, according to   The issue happens on ubuntu 12.04, and as it is cyclic but not frequent enough to make sure, I don't honestly remember if it happens on Windows 7 as well (it is a dual-boot machine). Rebooting the router won't help. Rebooting the computer fixes the problem, until it happens again.  It's been happening for a few months now. The last time it happened (earlier today) I performed a ping before and after the reboot. Here's the results:  before  $ping ajax.googleapis.com PING googleapis.l.google.com (74.125.21.95) 56(84) bytes of data. 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=1 ttl=47 time=157 ms 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=2 ttl=47 time=163 ms 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=3 ttl=47 time=156 ms 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=4 ttl=47 time=165 ms 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=5 ttl=47 time=157 ms 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=6 ttl=47 time=155 ms 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=7 ttl=47 time=159 ms 64 bytes from yv-in-f95.1e100.net (74.125.21.95): icmp_req=8 ttl=47 time=157 ms   after  $ping ajax.googleapis.com PING googleapis.l.google.com (74.125.134.95) 56(84) bytes of data. 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=1 ttl=47 time=207 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=2 ttl=47 time=154 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=3 ttl=47 time=154 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=4 ttl=47 time=152 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=5 ttl=47 time=157 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=6 ttl=47 time=160 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=7 ttl=47 time=154 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=8 ttl=47 time=157 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=10 ttl=47 time=154 ms 64 bytes from gg-in-f95.1e100.net (74.125.134.95): icmp_req=11 ttl=47 time=152 ms   The issue happens on different browsers, I installed epiphany and it shows the same behaviour.  I have inspected the network tab on firefox and it shows a single, unreplied GET request:   I installed wireshark and listened for HTTP GET requests; on other sites it pops up on the report, but on ajax.googleapis it shows nothing. I listened then for DNS requests, there are some differences:     If connect via telnet to the port 80 of a random site and perform a GET it works, but I can't telnet to ajax.googleapis.com (or it's IP), the connection never completes. Unable to locate package There are many  about Unable to locate package.  For example : if user try to install package by using apt-get then the following error shown. (Here package is used only as example for displaying error message):  sudo apt-get install package Reading package lists... Done Building dependency tree        Reading state information... Done E: Unable to locate package package   What does this error mean? How do I solve it?    provided General solution to understand and how to solve such type of error (which is helpful for new users that may unaware of repository-apt install mechanism)  Note : For resolving unmet-dependencies, visit: . A common technique after training, validating and testing the Machine Learning model of preference is to use the complete dataset, including the testing subset, to train a final model to deploy it on, e.g. a product.      My question is: Is it always for the best to do so? What if the   performance actually deteriorates?   For example, let us assume a case where the model scores around 65% in classifying the testing subset. This could mean that either the model is trained insufficiently OR that the testing subset consists of outliers. In the latter case, training the final model with them would decrease its performance and you find out only after deploying it.   Re-phrasing my initial question:     If you had a one-time demonstration of a model, such as deploying it   on embedded electronics on-board an expensive rocket experiment, would you trust a   model that has been re-trained with the test subset in the final step without being   re-tested on its new performance? Continuous function on R which tends to infinity on open interval must have a minimum Suppose we have $f : \mathbb{R} \to \mathbb{R}$ continuous and $$\lim\limits_{x \to \pm \infty} f(x) = \infty.$$  Then must $f$ have a minimum on $\mathbb{R}$?  Intuitively it seems so, and it's easy to prove for some arbitrary closed interval in $\mathbb{R}$ with the Extreme Value Theorem, but how can we apply that to an open interval like $(-\infty, \infty)$? Is there a vendor for animal parts? I'm looking to upgrade all my pouches, but some animals are hard to find, or the part needed drops rarely.  Is there a merchant somewhere that sells them outright? I have shards to spare. Zariski Tangent Space and $k[\varepsilon]/\varepsilon^2$ Let $X$ be a scheme over a field $k$, and let $x\in X$ be a rational point, that is, we have $k(x):=\mathcal{O}_x/\mathfrak{m}_x\cong k$.  Let $\alpha:\mathfrak{m}_x/\mathfrak{m}_x^2\rightarrow k$ be an element of $T_x=(\mathfrak{m}_x/\mathfrak{m}_x^2)^*$, the Zariski tangent space to $X$ at $x$.  Using $x$ and $\alpha$, I'd like to define a $k$-morphism of schemes Spec $k[\varepsilon]/\varepsilon^2\rightarrow X$.  In the course of the construction, I need to define a local map of local rings $\mathcal{O}_x\rightarrow k[\varepsilon]/\varepsilon^2$.  Using $\alpha$, what is a natural way to define such a map?  It might be helpful to note that I have an injection $k\hookrightarrow\mathcal{O}_x$ arising from the $k$-scheme structure on $X$.  I think this leads to a decomposition $\mathcal{O}_x/\mathfrak{m}_x^2=k\oplus(\mathfrak{m}_x/\mathfrak{m}_x^2)$ as $k$ vector spaces, from which the desired map would follow, but I can't seem to explicitly see what this decomposition is inside of $\mathcal{O}_x/\mathfrak{m}_x^2$.  This is part of exercise II.2.8 in Hartshorne. Dividing an equilateral triangle into N equal (possibly non-connected) parts It’s easy to divide an equilateral triangle into $n^2$, $2n^2$, $3n^2$ or $6n^2$ equal triangles. But can you divide an equilateral triangle into 5 congruent parts? Recently M. Patrakeev  an awesome way to do it — see the picture below (note that the parts are non-connected — but indeed are congruent, not merely having the same area). So an equilateral triangle can also be divided into $5n^2$ and $10n^2$ congruent parts.  Question. Are there any other ways to divide an equilateral triangle into congruent parts? (For example, can it be divided into 7 congruent parts?) Or in the opposite direction: can you prove that an equilateral triangle can’t be divided into $N$ congruent parts for some $N$?                                               (Naturally, I’ve tried to find something in the spirit of the example above for some time — but to no avail. Maybe someone can find an example using computer search?..) I’d prefer to use finite unions of polygons as ‘parts’ and different parts are allowed to have common boundary points. But if you have an example with more general ‘parts’ — that also would be interesting. I've been reading a Wikipedia article that describes the symptoms of rabies in various species, and I want to add a clarification note about which species (or species) a specific paragraph refers to. How can I make it clear that I'm referring either to the singular or plural of the word "species" when the singular of this word is the same as its plural? "Species or species" is the only grammatically correct way that I can think of, but it seems redundant and confusing. Is there any better way to contrast the singular of "species" from the plural of "species"? can we use past simple with for the past two days Silverlight - how do I get the text of the selected item in a combobox It is possible to press ⎇ Backspace on macOS in order to delete the previous word (left of the cursor), and ⌘ Backspace to delete the previous line (left of the cursor). If you have an external keyboard with a "delete" key (or the "forward delete key"), or are able to emulate the delete key via software, it is possible to press ⎇ Delete to delete the word to the right of the cursor. However, perhaps surprisingly, it is not possible to press ⌘ Delete in order to delete the line to the right of the cursor.  Now, I have only been able to make this possible by emulating a ⌘⇧→ and then a Backspace with BetterTouchTool. However, I want to avoid doing something like this because BTT does not work at a "low enough level" for me – that is to say, the action is not entirely reliable.  Is there any official macOS way to delete the line to the right of the cursor? I am new to ubuntu and i would like some help. I have a laptop with windows 7 installed but i would love to have ubuntu too because it's a great OS. So i would like to install ubuntu on an external usb hard drive (320 - 500 GB) and i have some questions about that :   Do i need a usb external hard drive which will be compatible with ubuntu - linux ? or i can do it with any hard drive  If i make a partition on it for ubuntu staff will i be able to use it and save other staff in the usb hard drive (movies,songs,documents etc) ? If i have ubuntu installed on the usb hard drive will i be able to boot ubuntu from any pc ? Are my changes going to be saved normally or my settings will be lost after shut down ?   Waiting for your answers, if something is not explain well tell me to try explain it better . Thank you! How Can i make save and load for bge I probably need the help of a Python script to make this work.  What I want is: The player will be able to save and turn off the game, but continue from where they saved when they next log in. Items such as gold, weapons, etc. must be stored.  It feels like something hard to do and I am not managing to figure it out alone. Although I love problems and solving them, in this case I need help.  I know that BSE People should not  ask more questions.  But.  Is this stupid or must I have several Scenes in my game. Say that my player goes into a house. Should the house then be in another Scene, or should I move camera and player to inside the house from the same Scene?  Any advice would be very helpful. I have no one near me whom I can ask.  //  Robin W Can someone please let me know the minimum system requirements and GPU requirement to run blender 2.80 and eevee smoothly?

Maximal order of an element in a symmetric group If we let $S_n$ denote the symmetric group on $n$ letters, then any element in $S_n$ can be written as the product of disjoint cycles, and for $k$ disjoint cycles, $\sigma_1,\sigma_2,\ldots,\sigma_k$, we have that $|\sigma_1\sigma_2\ldots\sigma_k|=\operatorname{lcm}(\sigma_1,\sigma_2,\ldots,\sigma_k)$.  So to find the maximum order of an element in $S_n$, we need to maximize $\operatorname{lcm}(\sigma_1,\sigma_2,\ldots,\sigma_k)$ given that $\sum_{i=1}^k{|\sigma_i|}=n$. So my question:      How can we determine $|\sigma_1|,|\sigma_2|,\ldots,|\sigma_k|$ such that $\sum_{i=1}^k{|\sigma_i|}=n$ and $\operatorname{lcm}(\sigma_1,\sigma_2,\ldots,\sigma_k)$ is at a maximum?   Example  For $S_{10}$ we have that the maximal order of an element consists of 3 cycles of length 2,3, and 5 (or so I think) resulting in an element order of $\operatorname{lcm}(2,3,5)=30$.  I'm certain that the all of the magnitudes will have to be relatively prime to achieve the greatest lcm, but other than this, I don't know how to proceed. Any thoughts or references? Thanks so much. Remove files with 0 length inside bash I want to create a bash script inside Linux terminal to go into a file and then delete it if it's empty:  #!/bin/bash echo " Enter name of a directory" read Dir for Directory in $( ls $HOME ) do    test -d $HOME/$dir   if [ $# -eq 0 ]   then      for filename in $( ls $HOME/$Dir )     do        test -d $HOME/$dir/$filename       if [ ! -s "$filename"  ]       then         rm $HOME/$dir/$filename       else          echo " not empty"       fi      done    else      echo " $Dir is not a directory"    fi  done   This is the code I am using but it does not work. It recognizes the file created but doesn't delete it even when empty. It Salah displays there is no such file or directory Single supply op amp to convert 0-5VDC to +/-2VDC (microcontroller to line level) I am generating a 0-5 volt sine wave using an arduino with a DAC. I would like to level shift this signal (DC bias?) by -2.5 volts and have a gain of .8, so that I end up with a line level sine wave.  Thus I am trying to design a single supply op amp with the following equation:  $$V_{\text{o}} = (V_{\text{i}}-2.5) \times 0.8$$  I found this white paper that is supposed to describe a way to do this but I'm having trouble following as I am new to op-amps.    Does anyone know of a way to do this with a single op amp or IC?  The frequency range of 20Hz to 20KHz must be preserved. Is there any way to index my Github account to google search. I see that many people's account show up as soon as I type their name, but mine doesn't show up even after I type my name followed by github n search.
