I am planning to migrate from Ubuntu 16.04 to Ubuntu 18.04 with a fresh install.. Has anyone tried the final stable release of Ubuntu 18.04? and Did anyone encounter any errors/issues while installing it? In other words, is it safe enough to try it now, or shall I give it more time before I install it?  Update: This is not about "new release missing or not found", it is about user experience while trying the new release.
Does anyone know the (specific) reasons that it is recommended that old LTS server users wait until the point release to upgrade?  Is it just a matter of bug fixes and waiting for improved stability for production servers, or is there something more fundamental than that?
We already had multiple questions about unbalanced data when using , , ,  and a number of other similar questions, what makes it a very popular topic! Unfortunately, each of the questions seems to be algorithm-specific and I didn't find any general guidelines for dealing with unbalanced data.  Quoting , dealing with unbalanced data     (...) heavily depends on the learning method. Most general purpose   approaches have one (or several) ways to deal with this.   But when exactly should we worry about unbalanced data? Which algorithms are mostly affected by it and which are able to deal with it? Which algorithms would need us to balance the data? I am aware that discussing each of the algorithms would be impossible on Q&amp;A site like this, I am rather looking for a general guidelines on when it could be a problem.

How do i prove invertibility of this linear transformation In older versions of Windows and even in Windows 10 previews you could enable the built-in guest account in control panel     Control Panel\User Accounts\User Accounts\Manage Accounts     In Windows 10, the Guest entry is missing.  Using Computer Management or net user you can still enable the guest account, but even then it doesn't show up on the logon screen.  In the Local Security Policy secpol.msc:     Local Policies - User Rights Assignment - Deny log on locally   we can see guest listed, this wasn't the case in older versions of Windows.  After removing guest from that policy, it is listed on the logon screen and we can using it to log on.  However, the whole Explorer shell is crashing and restarting constantly. The desktop is blinking and you can't click anything.  So the guest account is totally broken.   There is a  about this showing that some code was quickly added to the control panel to not show the guest account. So Microsoft does know about the problem.  While I don't really expect anybody to know what they've done to break this, at least this explains why the guest account is currently not listed. The arithmetic - geometric mean inequality states that $$\frac{x_1+ \ldots + x_n}{n} \geq \sqrt[n]{x_1 \cdots x_n}$$ I'm looking for some original proofs of this inequality. I can find the usual proofs on the internet but I was wondering if someone knew a proof that is unexpected in some way. e.g. can you link the theorem to some famous theorem, can you find a non-trivial geometric proof (I can find some of those), proofs that use theory that doesn't link to this inequality at first sight (e.g. differential equations …)?  Induction, backward induction, use of Jensen inequality, swapping terms, use of Lagrange multiplier, proof using thermodynamics (yeah, I know, it's rather some physical argument that this theorem might be true, not really a proof), convexity, … are some of the proofs I know. When using the Profile Tool plugin I get a graph that looks like the 2nd derivative of what I want. That is, it looks like the rate of change of the slope of the elevation profile. I just want the elevation profile! The data is present for good 1' contour lines. Why is the Profile Tool interpreting the data in such a bizarre way? What am I missing? And what are the Min and Max units? How do I right align controls in a StatusStrip? Is there any "superlogarithm" or something to solve $x^x$? Is there any "superlogarithm" or something to solve an equation like this:  $$x^x = 10?$$ Where should I put software I compile myself? I recently upgraded to Ubuntu 13.10, with the new keyboard handling system. The little "switch keyboard" option does not let me set it to Alt+Shift.
