I'm a complete newbie to this, so I'm going to need a full walkthrough with as little jargon as possible. Short story: I bought a used laptop that's in great shape off ebay. Dell Latitude, 16 gb ram, 128 gb ssd, i7-5600u core. Bit old, good heart. However, it has no os, just the bios. How can I get Ubuntu on here with as little fuss as possible? I have only worked with Windows vista, 8, and 10, plus chrome os and I've never had to install an is before. I have access to computers running on chrome os and Windows 10, plus mysterious hard drives my dad left when he died. I also have some flash drives in varying states of functionality, and HDMI cables that were being used to connect my previous laptop to the tv because the screen broke but all else was fine. My dad also left a whole drawer of mysterious cables I don't know the names of. Hope this is enough info, tell me if in my ignorance I left something out. Thanks in advance!
I would like to see a full how-to guide on how to install Ubuntu.
PDF of product of variables Could anyone please indicate a general strategy (if there is any) to get the PDF (or CDF) of the  product of two random variables, each having known distributions and limits?   My particular need is the following: Let $w :=u \cdot v$. The PDF of $u$ is $$\frac{1}{\pi u}\frac{1}{\sqrt{u^2-0.25}},$$ for $z&gt;0.5$ and the PDF of $v$ is $$\exp\left(-\frac{v}{v_0}\right),$$ for $v_1&lt;v&lt;v_2$. What's the PDF of $w$? What plane type will I need to go transatlantic in Pocket Planes? I'm based in North America and have a bunch of major airports on the Eastern Seaboard.  I'm level 14 and just unlocked the Pearjet, but I still don't have a plane with enough range to make it across the Atlantic.  What's the first plane I'll get that will let me make that crossing?  Or more specifically, what's the range from New York (or Boston) to London (or Lisbon) - the smallest range that'll get me across? rtl8723ae unstable on Ubuntu 14.04 I have searched through the internet and in AskUbuntu, but I could not find a working solution for my little problem.  The RTL8723ae WLAN is behaving strangely on Ubuntu 14.04 and drops the WLAN connection constantly. I am using the notebook MSI GE40 and have already seen on the web that there are other people having the same problem but there was no permanent solution. The problem did not exists on the original Windows 8 on the device and the router is a TP-Link, which I can control (channel change and so on, I use WPA2-PSK WLAN security). Best way to run scheduled tasks Today we have built a console application for running the scheduled tasks for our ASP.NET website. But I think this approach is a bit error prone and difficult to maintain.

In FHS-2.3, we have /media that holds mount points for removable media such as CD-ROMs and we have /mnt that holds temporarily mounted filesystems.  On the other hand, we have /run/media and /run/mount. For me, the CDs and USBs are mounted on /run/media.  I don't see any clear distinction between them(/media, /mnt, /run/mount) . What are their differences?     I have seen similar trend (mount on /run/media) in fedora 20 - GNOME 3.10.4 and ubuntu 14.04.1 (installed on virtual box) with GNOME 3.10.4. But when I plugged in a USB flash (with auto-mounter script) on a system with Centos 6 and GNOME 2.28.2 it was mounted on /media I am trying to use the AwesomeCV template () for creating a CV using TexMaker 5.0.3 with XeLaTex. However, I am not able to get this to work as I get the following error messages:    Does anyone know what the source of problem might be and how to solve it?  Thanks a lot in advance,  Cheers Proof that an integral domain that is a finite-dimensional $F$-vector space is in fact a field Log form of variables and descriptive measures Because of larger values of variables, I did a log- transformation in my dataset. Now I want to give a descriptive table regarding my variables like mean, max, min, median, skewness, kurtosis. Can I give standard measures like arithmetic mean or should I give geometric mean? In terms of skewness or kurtosis, do I need a transformation? What is a good set of naming conventions to use when developing on the Force.com platform? I've looked in the Apex developer's guide and a saw the   which has basically only has this:   We recommend following Java standards for naming, that is, classes start with a capital letter, methods start with a lowercase verb, and variable names should be meaningful.   I'm looking for something more in depth, such as end all Controllers with Controller and their tests with ControllerTest, etc.  What is a good set of naming conventions to use when developing on the Force.com platofrm?  It would be preferable if the answer has something that handles custom objects, classes, visualforce pages, and components and not just Apex classes.

I wrote a comment on the second post, explaining that the answer to his question is in the linked duplicate and that he shouldn't circumvent the closure process by asking a second identical question.  When the second post was closed as a duplicate my comment was automatically deleted. As far as I understand this is a heuristic that removes obsolete comments, which it considers every comment that contains a link to one of the duplicates.  This heuristic is too aggressive and removes comments that go beyond "Duplicate here: link". I suggest that it should be changed to only remove the default duplicate comment, and not any comment that was edited by the owner nor any free-form comment that happens to include a link to the duplicate.  This also triggers for any comment that contains the word "duplicate" and link to any question, not only the question being chosen as duplicate, which makes this much worse. Why is the probability that a continuous random variable takes a specific value zero? My understanding is that a random variable is actually a function $X: \Omega \to T$, where $\Omega$ is the sample space of some random experiment and $T$ is the set from which the possible values of the random variable are taken.  Regarding the set of values that the random variable can actually take, it is the image of the function $X$. If the image is finite, then $X$ must be a discrete random variable. However, if it is an infinite set, then $X$ may or may not be a continuous random variable. Whether it is depends on whether the image is countable or not. If it is countable, then $X$ is a discrete random variable; whereas if it is not, then $X$ is  continuous.  Assuming that my understanding is correct, why does the fact that the image is uncountable imply that $Pr(X = x) = 0$.  I would have thought that the fact that the image is infinite, regardless of whether it is countable or not, would already imply that $Pr(X = x) = 0$ since if it is infinite, then the domain $\Omega$ must also be infinite, and therefore  $$Pr(X = x) = \frac{\text{# favorable outcomes}}{\text{# possible outcomes}} = \frac{\text{# outcomes of the experiment where X = x}}{|\Omega|} = \frac{\text{# outcomes of the experiment where X = x}}{\infty} = 0$$  What is wrong with my argument?  Why does the probability that a continuous random variable takes on a specific value actually equal zero? Why are heatmaps on qgis 2.8.1 produced in the wrong CRS? I noticed that the heatmap calculation on the new upgrade version of qgis is given the raster map without any coordinate system.   Have you got the same problem?
