Why is my kernel not upgraded to the latest version? My server runs Ubuntu 12.04.5 LTS. I try to keep it up to date as possible by doing  sudo apt-get update &amp;&amp; sudo apt-get upgrade regularly. So far I was assuming that this would update the kernel as well. Today I noticed however that I am running a totally outdated kernel (uname-r gives 3.2.0-77-generic).   Doing sudo apt-get dist-upgrade didn't fix this. Then I tried sudo apt-get install linux-generic linux-headers-generic linux-image-generic - also with no success...  Why am I not receiving the latest kernels and how can I fix this?
How to Upgrade Ubuntu 12.04.2, 12.04.3 to 12.04.4, the next Hardware Enablement Stack? I am currently using Ubuntu 12.04.2 32bit. I installed it using LiveCD.  Tomorrow, 23rd August 2013,Ubuntu 12.04.3 is released. I want to upgrade from Ubuntu 12.04.2 to Ubuntu 12.04.3 without using any LiveCD. Is it possible? If so please suggest me how can I do.  Actually while using Ubuntu 12.04.2 I have troubled with graphics. My graphics card is Intel i845G 64 MB. When Ubuntu starts it works fine and smooth without any lagging, but after sometime it hangs for few seconds (1 or 2 seconds) with a garbage screen and becomes sluggish. All windows and browsers start lagging and also it is not possible to play any video in any player (VLC, Movie Player, Xnoise, SMPlayer etc..).  I think Upgrading to Ubuntu 12.04.3 could fix my problem.  Any help will be greatly appreciated..    I've posted an answer to upgrade Ubuntu 12.04.x to 12.04.4.

Good and easy way to share files on local machine I would like to have a directory that has following properties:    Many users can copy files into it  These files can be deleted/changed by these users (user A can delete/modify file that was copied into this directory)    it cant be done using normal file permissions (because permissions are retained on copy).  Here is what I found on the net:        Some use cases:    Sharing music on local machine  Simple git repository sharing (just make a bare repository writeable to many people) --- i know that there are solutions like gitosis Allow many developers to modify test instance of php app without giving them root (i guess they would copy files) --- I'm leading a team of nonprofit junior developers and I need to keep that one simple!

How can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE? I want to install Oracle's JRE and to update to the latest version with the Software Updater when they released. Is there a Ubuntu package that is provided by Canonical or Oracle?  Before release Java 7, I followed  to install Java 6.  But it doesn't work for Java 7. There is no package sun-java7-xxx. How can you install Java 7? I've got a PHP script that needs to invoke a shell script but doesn't care at all about the output. The shell script makes a number of SOAP calls and is slow to complete, so I don't want to slow down the PHP request while it waits for a reply. In fact, the PHP request should be able to exit without terminating the shell process.  I've looked into the various exec(), shell_exec(), pcntl_fork(), etc. functions, but none of them seem to offer exactly what I want. (Or, if they do, it's not clear to me how.) Any suggestions? Perhaps this is trivial: how does one prove that the work done by a homogeneous gravitational field on a system of particles is equal to the work done on a point mass with the total mass of the system, located at the center of mass of the system. the largest integer $n$ for which $n+5$ divivides $n^5+5$?

"Neither", "none", "no one" + [of them] + verb-s In a comment on English Language &amp; Usage I read the following answer responding to a(n) asker's question: &quot;Neither sound natural.&quot; I have always had more than one doubt on the &quot;neither&quot; usage and I would like understand(ing) the &quot;secrets&quot; to use this word better or, at the best, correctly. So, let us consider the following examples:  1 Neither sound natural. 2 None sound natural. 3 No one sound natural. 4 Neither of them sound natural. 5 None of them sound natural. 6 No one of them sound natural. 7 Neither sounds natural. 8 None sounds natural. 9 No one sounds natural. 10 Neither of them sounds natural. 11 None of them sounds natural. 12 No one of them sounds natural.  Comparing the above sentences (one) with each other, can anybody explain which is grammatical and why? I have a program which I am trying to run, however when I run it; it just complains that it can't find a particular file.  However I have no idea which folder it is trying to find this particular file in. I have a copy of the required file, I just need to know which folder to copy it too.  Is there any way to show in real time which files are being accessed or which files are trying and failing to be accessed?  I am using Ext4 filesystem if that helps.  Thanks How does the Rectified Linear Unit (ReLU) activation function produce non-linear interaction of its inputs? When used as an activation function in deep neural networks The ReLU function outperforms other non-linear functions like tanh or sigmoid . In my understanding the whole purpose of an activation function is to let the weighted inputs to a neuron interact non-linearly. For example, when using $sin(z)$ as the activation, the output of a two input neuron would be:  $$ sin(w_0+w_1*x_1+w_2*x_2) $$   which would approximate the function  $$  (w_0+w_1*x_1+w_2*x_2) - {(w_0+w_1*x_1+w_2*x_2)^3 \over 6} + {(w_0+w_1*x_1+w_2*x_2)^5 \over 120} $$  and contain all kinds of combinations of different powers of the features  $x_1$ and $x_2$.   Although the ReLU is also technically a non-linear function, I don't see how it can produce non-linear terms like the $sin(), tanh()$ and other activations do.  Edit: Although my question is similar to , I'd like to know how even a cascade of ReLUs are able to approximate such non-linear terms. Summing up the area on a polygon by a certain attribute result I wish to know if there's a tool on QGIS equivalent to the Excel's "SUMIF".    I have a shapefile of a land use and cover that's classified by the attribute with the name of the classes, for example: "vegetation", "urban centers" and "pastures". My goal is to calculate the area of each class, but since it's composed by various polygons, I need to add up all the areas from all polygons that were put in the same class.  Like I mentioned in the beginning of the question, I know that Excel has a function that can do such thing for me, but it turns out that the sum made by excel doesn't match the area's total given by QGIS.  English is not my first language, so if the explanation isn't clear enough, I'll be glad to rephrase it. Gparted: move extended partition on the left I have some free disk space on the left of my ubuntu (sda5)  What is best solution to extend sda5 ?  I can    copy sda3 or sda5 with dd to bigger disk. delete sda3,5,swap create sda3,5,swap dd original partition.   Not sure how to do it properly.  May be there is a simpler solution. Okay setting the scene. I have three tables, (Table1, Table2 and DataTable) and I want to insert into Table1 and Table2 using DataTable as source. So for every row in DataTable I want a row in Table1 and Table2, and Table2 needs to have the inserted id (PK) from Table1...  If I were to do this...  INSERT INTO Table1 SELECT A, B, C FROM MyTable INSERT INTO Table2 SELECT IDENTITY_INSERT(), D, E, F FROM MyTable   I'd get the ID of the last inserted record into Table1.
