Can't see my 'other Locations' option in Ubuntu 18.04 desktop
Nautilus does not show the left bar, how do I turn it back on?
I would like to install Ubuntu 14.04.02 LTS on my machine which currently has Mageia 4.1.   So, I have the following partitions: One for /, one for swap and one for /home.   I have some important data on /home which I wouldn't like to lose (I have backed them up, but I would prefer to keep them) after a clean install. I plan to reformat partitions one and two as above and keep the /home one.   Will I be able to tell Ubuntu to do so during an installation? By this I mean: Will it be able to recognize the /home partition and keep all its data intact while formatting the rest? And one more question: Will it be able to keep the users as they are our will I be forced to change them too? (I have the bad feeling that it won't be able to keep the users as they are...) Safari can load internet but none of the other apps cannot! This is by far the weirdest problem I've come across,  My mac can perfectly access internet through safari web browser, but when I tried to do   ping www.google.com   through the terminal, it's requests is being timed out.  None of the other apps are able to reach internet either. Dropbox, Skype, Spotify all showing offline, except the browser itself  I'm guessing something bad with the DNS, but spend 2 hours trying to fix this with no luck Chrome and IE 11 are fine, I'm only able to reproduce this in Firefox.

Would you please explain the difference between these two sentences?     Spain ceded (or gave) Puerto Rico to the United States. Since then, Puerto Rico has been a U.S. territory.      Spain ceded(or gave) Puerto Rico to the United States. Since then, Puerto Rico was a U.S. territory.   I am stuck between 'has been' and 'was' in the above sentences. It looks like if I load dynamic content using $.get(), the result is cached in browser.  Adding some random string in QueryString seems to solve this issue (I use new Date().toString()), but this feels like a hack.   Is there any other way to achieve this? Or, if unique string is the only way to achieve this, any suggestions other than new Date()? Assigning integer to finite CW complex such that following hold.

Execute shell script or command on idle time I'm searching for the possibility to execute a shell script or command based on idle time in the bash shell.  As an example, if I'm in a SSH session to a server of mine and after X minutes of inactivity in the terminal, I want a command to start a desired program like cmatrix, and when I come back and press a key I will get back where I left. Matrix Group induction proof and order of elements question How to fetch the columns of the synonyms for linked servers in SQL server I am using two servers local (SQL Server running on my system) and remote (SQL Server running on another system). I have created synonyms in my local server for a table which is located on the remote server.  Synonym used- CREATE SYNONYM [dbo].[test] FOR remoteserver_name .[database_name].[schema_name].object_name  Requirement   I need to fetch the columns of the synonym.  I can retrieve the columns of the synonym using below query in SQL server.  select * from dbo.test   where  dbo is synonym created schema name (local server schema name) and test is synonym name.  I have tried to retrieve the columns of the synonyms using below query, but I cannot fetch the columns  SELECT sys.schemas.name   AS SCHEMA_NAME,        sys.synonyms.name  AS view_name,        sys.columns.name   AS COL_NAME,        sys.types.name     AS data_typename FROM   sys.columns        INNER JOIN sys.synonyms             ON  OBJECT_ID(sys.synonyms.base_object_name) = sys.columns.object_id        INNER JOIN sys.schemas             ON  sys.schemas.schema_id = sys.synonyms.schema_id        LEFT OUTER JOIN sys.types             ON  sys.columns.system_type_id = sys.types.system_type_id WHERE  sys.types.system_type_id = sys.types.user_type_id        AND sys.schemas.name = N'scehmaname'        AND sys.synonyms.name = N'synonymname'   Can you please suggest some other way to retrieve the columns of the synonym or correct the above query? Multivariable limit proof: $\lim\limits_{(x,y)\rightarrow (0,0)}\frac{\left|x\right|^a\left|y\right|^b}{\left|x\right|^c + \left|y\right|^d} = 0$ I have some trouble with this: Show that if $a, b \ge 0$, $c, d &gt; 0$ and $\frac{a}{c} + \frac{b}{d} &gt; 1$ then   $$\lim_{(x,y)\rightarrow (0,0)}\frac{\left|x\right|^a\left|y\right|^b}{\left|x\right|^c + \left|y\right|^d} = 0$$  we were not really shown how to evaluate multivariable limits other than trying different paths, which wouldn't work when the limit exists, or by applying the squeeze theorem which is my initial plan. Unfortunately I cannot find a proper bound for the denominator and so I am quite lost right now. Any help would be appreciated. I think the questions says it all! :)  By TeX, I mean any derivative of TeX as long as the code is clearly a derivative of TeX, i.e. that it could belong on TeX.SX (and not pure Lua for example).  I'll give two answers myself so you see what I mean. How to contact Canonical? So I am doing a College research project for my Computer Information Systems department and it is about alternative Linux server distribution for small businesses. From my findings I would really like for this research to actually take off into a Distribution project (Using Ubuntu as a base OS).   However I would like to rename the distribution as "Bizbuntu" or something related to that ("Biz" being shorthand for business) however I don't know if I can name the distribution without consent from Canonical.   So my question is do I have to contact Canonical about this, if so, does anyone know a mailing list or email that I can contact them about this? I have a WordPress install on a dedicated server with decent memory (upwards of 8GB).  The WordPress install includes many plugins - 50 active plugins. Most important to note is the  plugin to make WordPress multilingual. The theme is .  The stack is LAMP - CentOS 6.3, Apache 2.4.4, Percona MySQL, PHP-FPM.  I have been quite stupid, and didn't set up a test or staging server.  Everything was running fine till I updated to WordPress 3.8, and also updated several plugins at the same time.  I didn't pay attention at the time, but all my widgets got messed up, and so did any sort of navigation etc.  I enabled error_log for a bit, i.e.  ini_set('log_errors',TRUE); ini_set('error_reporting', E_ALL); ini_set('error_log', dirname(__FILE__) . '/error_log.txt');   This resulted in an immense file - basically the error_log grows by about a GB every 4 minutes or so.  The primary error I found in the error log was database server disconnect, better known as      MySQL server has gone away   The first priority was to patch the problem. So I installed  plugin. This mostly, though not completely solved the issue. Many of the widgets came back.  However, the special (non-English) characters are all messed up (converted to question marks). I tried to fix this by opening wp-mysql-ping.php and commenting out   if ( !DB_CHARSET &amp;&amp; version_compare(mysql_get_server_info($this-&gt;dbh), '4.1.0', '&gt;='))                                     {                                         $this-&gt;query("SET NAMES '" . DB_CHARSET . "'");                                     }   Didn't help.  Besides, the plugin is not a permanent or complete solution. So leaving the site in this messed up state, I started working on other possibilities:  As suggested at , I edited my.cnf to add  wait_timeout = 60   Didn't help.  Also added caching to my.cnf  query_cache_type = 1 query_cache_limit = 8M query_cache_size = 512M   Didn't help.  (and yes, I restarted mysql every time I edited my.cnf)  Also tried the method : In wp-db.php before  $this-&gt;select( $this-&gt;dbname, $this-&gt;dbh );   I added  $this-&gt;query("set session wait_timeout=600" );   Didn't help.  I'm at my wit's end. Please help!
