I am trying to upgrade my Ubuntu virtual machine (currently 12.10) to 13.04 and then eventually to 13.10. I ran the update manager and it says "The software on this computer is up to date. However, Ubuntu 13.10 is now available (you have 12.10)."   If I hit the 'upgrade...' button will it install 13. 04 or 13. 10? I know it is highly recommended that users update from version to version and I am worried if I just hit 'upgrade...' button then something might get messed up upgrading straight to 13. 10 if it skips over 13.04. Any ideas?
Looking at   13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be unable to upgrade.  I asked this question a number of months ago and the suggestion was that the hope was that there would be an upgrade path from 12.10 to 14.04.  Could somebody confirm whether this is still the case, or if not what the plans are for 12.10 users after 13.04 becomes EOL.  Edited for clarification  The particular issue I was concerned about is that once 13.04 goes EOL, a 12.10 user would in theory lose the ability to upgrade once the 13.04 repo's are removed from the normal release repository.  Using the old releases method would be a way around the issue, however would make it more complicated for a less experienced user.  An alternative could be for the 13.04 repo's to be left available for the 3 month interim period so that a 12.10 version could still be upgraded to 13.04 and subsequently onto 13.10, however that doesn't seem an optimal solution in that users may consider that it meant that support for 13.04 was being continued.  If a direct upgrade from 12.10 to 14.04 was to made available, this would only be available once 14.04 was released and still leaves the issue of the 3 months between January and April 2014 were there may be some confusion.  I suspect that its not going to affect a significant number of users, if somebody has upgraded from 12.04LTS to 12.10, in all probability, they'll have continued to upgrade to 13.04 and upwards because they'd made the choice to use current rather than LTS releases.  It would just be useful to have some clarification of the situation which people can be referred to in advance of 13.04 going EOL rather than hitting the cut off point and it being too late for users to make the decision and being left in limbo.
This was working perfectly on 17.10 but after upgrading to 18.04 yesterday, when the lid is closed the screen turns off but doesn't suspend properly.  I travel around a lot and immediately noticed the heat (and battery draining) when taking it out of the travel case.  I've tried uncommenting these lines in /etc/systemd/logind.conf  HandleLidSwitch=suspend HandleLidSwitchDocked=suspend   and restarted but didn't make any difference. What is the main difference between StringBuffer and StringBuilder? Is there any performance issues when deciding on any one of these? Simplify a combinatorial sum Why is $\sum_{k=0}^n (_k^n) 2^k$ simplified as $3^n$ and not just $2^n$ ? The answer uses the binomial theorem as a solution: let $a=1$ and let $b=2$. So $1+2 = 3$. But since $1+2 = 3$ why do we not use $1+1 = 2$? How does Incense work? Set Path for all Users (Login and Non-login Shells) Ok. So, I'm used to Ubuntu and CentOS more than redhat, so I'm hoping there's some obvious solution to this that I'm missing.  I've installed Anaconda (Python). I've placed it in:  /opt/anaconda3   I would like for myself and all users to be able to have the following in their paths:  /opt/anaconda3/bin   I have googled around and have gained a lot of conflicting information about how to "properly" accomplish my mission.  Stuff I have tried:   Adding a bash script to /etc/profile.d Editing /etc/profile Editing /etc/bashrc Adding to root bashrc Editing user .bashrc   All edits involved some form of:  PATH=/opt/anaconda3/bin:$PATH   or  export PATH=/opt/anaconda3/bin:$PATH   Option 2 yielded the addition of /opt/anaconda3/bin to the path for multiple users, but after terminal restarts still did not run the commands within bin (i.e. conda install, ipython notebook, etc.)  Any ideas? Is this algebraic identity obvious? $\sum_{i=1}^n \prod_{j\neq i} {\lambda_j\over \lambda_j-\lambda_i}=1$ It's big and empty and I can't get up to the top, what should I do? I can't jump high enough, anti-gravity doesn't seem to do anything either.  My first tactic was to use the octopus summoning crown to create a pile of octopi that I could climb up, but when I teleported to the back of the room they followed me back, trapping me in the entrance. Best way to make family photo album in LaTeX I use LaTeX for my research publishing and would like to make a Christmas photo album that I could send to a print shop. It occurred to me to try it with LaTeX this time (yes I know, the print version won't get delivered by Christmas). Among other reasons, it will look like I'm working on code! But I would benefit from some templates etc. and haven't had luck finding any.  Can anyone recommend resources for building a family photo album in LaTeX? How to embed a view in a specific node? I try to embed a view in a specific node. I found tutorials for doing this with Drupal 7 and PHP-Templates:  &lt;?php print views_embed_view('view_name'); ?&gt;   But I look for a way in Drupal 8 with twig-Templates. I tried to call the views_embed_view() function in the hook_node_view() and assign it to the node so that I can print it out in the twig-Template. But it seems that this hook never gets called.  Any hints/solutions how to do this in the Drupal 8 way? Distribution of Product of Random Variables with one being the normal distribution. How can I access google.com outside the US? I live in the UK, and whenever I visit google.com I am redirected to google.co.uk, but I want to see my website's rankings on the US version (I presume the results are different). Is there a way to do this? Why do we focus so much in math on functions (as a subclass of relations)? Why is it that math so focuses on the subclass of relations known as functions? I.e. why is it so useful for us in nearly all branches of mathematics to focus on relations which are left-total and left-unique? Left- (or even right-) totality seem to be intuitive, since if an element doesn't appear in the domain, we might throw it out. But why left-uniqueness?  I'm looking for something like a "moral explanation" of why they would be the most useful subclass of relations.  My apologies if this is a previous question; I looked and didn't find much. Can't login with Stack Exchange OpenID when HTTPS-Everywhere plugin is active - apparent protocol mismatch I can't seem to log in with my Stack Exchange OpenID. When I try, I get the error message:     Unable to log in with your OpenID provider:      The openid.return_to parameter (.) does not match the actual URL (.) the request was made with.   It works if I disable the HTTPS-Everywhere plugin in Firefox, but if I then re-enable the plugin and go to a site on which I am not logged in (in which case login is normally nearly seamless), it fails again with the same error message, or at least something very similar.  I'm not aware of having done anything that might have caused this, although I will admit I don't recall seeing https:// in the address bar on Stack Exchange before (I do now, and that's a good thing IMO!). I was using the site  and it worked fine then, but not now... Ethernet indicator in OSX menu bar I am using OSX 10.7  When I move between different ethernet networks (e.g., at work using ethernet on an external display, at home using thunderbolt ethernet), the ethernet does not always connect. However, I don't get immediate feedback. Instead, I connect to wi-fi. However, wi-fi is both slower and less reliable than ethernet. Thus, I'd like to know whether I am connected to ethernet or not. Of course I can go into preferences and network settings to see whether I'm connected to ethernet, but it would be better if there was some form of indicator in the status bar, just as there is for wi-fi. Thus, my question:  Is there a way of getting an indicator of ethernet connectivity in the OSX menu-bar?  Perhaps there is a free application that can do this. I need to start by stating that I have read through every single problem on here relating to mine, but all of them seem to have access somehow to their server's files. I do not, so here is my question.  I'm on centOS 6.5 and ssh closes connection right after a successful login. I am using mac and windows/putty to access my server with the same results.

How to remove the "No front page content has been created yet." message from the front page? I only want blocks on the homepage.

If $(V,|.|)$ is finite dimensional inner product space of dimension $n$ then it is (topologically) isomorphic to $\mathbb{R}^n$ which is of course complete. My instinct here is to say "and therefore, $V$ is also a Hilbert space". I'm not sure about this step however since completeness depends on the norm and the norm depends on the selected inner product (assuming the induced norm $||x|| = (x | x)^{1/2}$ is used). So, must we place some condition on the inner product or is the topological isomorphism between $\mathbb{R}^n$ enough to guarantee that V is Hilbert?
