Since drush 9 (drupal 8.4 requirement), alias @sites does not seem to be implemented anymore (or yet ?).  $ drush @sites cr The alias @sites could not be found.   Is this a way to get the same behavior that does not consist of typing my 300 alias in a config file ?
In Drush 8, my site aliases are loaded correctly from ~/.drush/mysite.aliases.drushrc.php.  E.g.  $aliases['dev'] = array(   'root' =&gt; '/var/www/html/mysite.dev/docroot',   'uri' =&gt; 'mysite.prod.acquia-sites.com',   'remote-host' =&gt; 'mysite.ssh.acquia-sites.com',   'remote-user' =&gt; 'mysite.dev',   'path-aliases' =&gt; array(     '%drush-script' =&gt; 'drush' . $drush_major_version,   ), );   However these aliases aren't loaded in Drush 9.  $ drush site-alias {  }   How I should define site aliases in Drush 9? Is there any migration process?

In a Youtube video by ADVChina, the speaker is recommending using a VPN in China for various reasons, and to sign up using his referral code.  He says there are various practical uses including "You could also go and get cheaper plane tickets by hopping around different countries." and shows a screenshot of a flight website called KAYAK, with the VPN software changing his country to Italy.  Is it possible to get cheaper plane tickets by using a VPN in this way? I've never heard of KAYAK, but if I use something like Skyscanner, is it common for tickets to be priced differently depending on which country the user's IP is from?  Is it because of different taxes in different countries? So could it be illegal to get discounts like this? Or is there some pricing strategy from airlines to charge different amounts depending on the country of purchase? Are there any programs that will let me dictate (speech-to-text) to any program? Or at least to a text editor and text fields in Firefox.  I’m not interested in anything that uses an online service, it has to be on-device. It may be a commercial product. I am moving from Malaysia to the US, and planning to bring my desktop computer with me. I plan to pack it in my checked-in luggage. Will the computer risk being damaged? Any precaution should I take to reduce this risk? Will there be any trouble with the airline or immigration about bringing computer? How find the maximum value of $|bc|$ Question:     Given complex numbers $a,b,c$, we have that $|az^2 + bz +c| \leq 1$ holds true for any complex number $z, |z| \leq 1$. Find the maximum value of $|bc|$   It is said this is answer is $$|bc|\le \dfrac{3\sqrt{3}}{16}$$  My idea: let $z=1$,then $$|a+b+c|\le 1$$ let $z=-1$,then $$|a-b+c|\le 1$$ let $z=0$, then $$|c|\le 1$$  let $|\theta|=1$,then we have $$|a(z/\theta)^2+b(z/\theta)+c|\le 1\Longrightarrow |az^2+b\theta z+c\theta^2|\le 1$$ and only this can't solve this problem,Thank you Solve the recurrence $T(n) = 2T(n-1) + n$ Solve the recurrence  $T(n) = 2T(n-1) + n$ where $T(1) = 1$ and $n\ge 2$.

Isomorphism between two models of Hilbert's Axioms with different notions of congruence xdg-open on debian 9 fails to open browser I decided to try lxdm (was using fluxbox and xfce), and discovered that for many programs the url handler was failing, producing this error message;   Quite strange as you can see, it's prepending the user directory to the url.

What all is affected by the spell? Is gravity affected? Air movement?  I know that the spell only does what it says, and nothing else, but just wondering.   In addition, is it saying that the other creatures are not affected by environmental effects and the like while time is stopped?  For instance, if a wind blew really hard at one of the creatures you're fighting, would it affect that foe while time stop is active? If you were to place a bear trap behind the person, and a hard wind blew enough to tip them, would they then fall over onto the bear trap and be damaged without the spell ending?

Unable to set DYLD_FALLBACK_LIBRARY_PATH in shell on OSX 10.11.1 In shell scripts used for unit testing with dynamic libraries in a directory other than the typical @rpath, I have previously been able to set DYLD_FALLBACK_LIBRARY_PATH to set the directory containing the libraries. Under 10.11.1, bash seems to ignore attempts to set this environment variable:  $ sh -x testscript.sh + DYLD_FALLBACK_LIBRARY_PATH=/Users/something/testinglibs + export DYLD_FALLBACK_LIBRARY_PATH + exec printenv   and DYLD_FALLBACK_LIBRARY_PATH is not present in printenv's output.

I have used Windows since childhood, and when I hear the phrase "Windows filesystem" I think of directories (folders) within directories, a folder called SYSTEM, a folder called PROGRAM FILES etc. Is this what the system is? Just the layout of the folders?  And then I recently started using Linux, and my reference book says in the linux filesystem everything starts at root and branches off from there. How is that really different from Windows? I mean, it seems the linux system and the windows system are just two ways of setting up a directory tree.
