Using OpenStreetMap data in QGIS, but street names repeat too much
Labeling (one-way) streets in QGIS?
If an effect would prevent a spell from doing damage, does it continue to prevent that damage after the spell changes zones? Anthony casts , targeting Nathan's .  Nathan casts and resolves , choosing to 1) prevent all damage that would be dealt by Searing Blood this turn and 2) put a +1/+1 counter on Elvish Mystic.  Searing Blood resolves, deals no damage, and goes to the graveyard.  Anthony casts and resolves  to kill Elvish Mystic.  Searing Blood triggers from the graveyard, because Elvish Mystic died. Does the prevention effect created by Dromoka's command still apply to it after it changes zones? In other words, will Searing Blood deal 3 damage to Nathan? command not running in cron (systemctl suspend) Infinite series for $e$... How do you prove that $e=\sum_{n=0}^{\infty}\frac{1}{n!}$? Here I am assuming $e:=\lim_{n\to\infty}(1+\frac{1}{n})^n$. Do you have any good PDF file or booklet available online on this? I do not like how my analysis text handles this... Not booting from USB or CD (SYSLINUX Message) I am trying to install linux on my laptop, a Toshiba Satellite C6550-S5200. I did it once but something happened so I removed it then I had to destroy all data on hard drive so now I have nothing on it. Well I got a iso file burned to a CD and to a flash drive. With the flash drive I get.   SYSLINUX 4.06 EDD 4.06-pre7 Copyright (C) 1994-2012 H. Peter Anvin et al  With the CD it will start booting it but somewhere loading it up, the dots turn all orange and stay that way and my CD drive turns quiet.  Oh and some more info the images work because I tried loading them up on another pc and it worked just fine.  I manage to get the CD to boot I just had to let me pc boot up first then insert the CD and have it boot the CD then. Once I get done installing ubuntu it works fine but I have to leave the PC on 24/7 for if I turn it off the PC will freeze 5-10 seconds after booting back up no matter how I install it. I just installed Ubuntu 18.04 and one of my first negative impressions is the long animation of flying-in icons when opening the app menu.  Can I speed this up or disable it? du not accounting for space shown by df I have a CentOS 7.2 (minimal) VM running in a vSphere cluster, which has a 16G drive formatted as XFS under the default full-disk usage partitioning scheme from the CentOS installer. The system is running a test httpd service (all software from the default centos repos), but its space usage on disk is growing. This is in part from problematic apache error/access logs (2+GB in size), and removing these longs frees up some space. What is eating the drive space isn't so much a concern for me (I'll just nuke and pave this eventually). However, when I run df an du to check file sizes, I get a discrepancy and this is what's confusing.  First I run df -h to view filesystem usage:  [root@svrhttp03 httpd]# df -h Filesystem                         Size  Used Avail Use% Mounted on /dev/mapper/centos_svrhttp03-root   14G  4.8G  9.1G  35% / devtmpfs                           902M     0  902M   0% /dev tmpfs                              912M     0  912M   0% /dev/shm tmpfs                              912M   97M  816M  11% /run tmpfs                              912M     0  912M   0% /sys/fs/cgroup /dev/sda1                          497M  169M  329M  34% /boot tmpfs                              183M     0  183M   0% /run/user/0   This is showing 4.8G used on the root FS.  I then run the following to view the size of all items at the root of the filesystem:  [root@svrhttp03 httpd]# du -a -h -t 10K / 2&gt; /dev/null | grep -v -E "[A-Z,a-z,0-9]/." | sort -h 16K /home 7.4M    /root 31M /etc 97M /run 143M    /boot 324M    /var 1.3G    /usr 1.9G    /   This shows only 1.9G in use, and the reported size of all directories add up to ~1.9G, as expected.  So how can I find that ~2.9G discrepancy between what df and du are claiming for data on disk? How do I login as root? How to obtain optimal hyperparameters after nested cross validation? For a given ellipse, find the locus of all points P for which the two tangents are perpendicular.   I have a trigonometric proof that the locus is a circle, but I'd like a pure (synthetic) geometry proof. Select Command not working while run shell scripts on remote machine The complex general linear group is a subgroup of the group of real matrices of twice the dimension and with positive determinant.  Let us decompose complex matrices $M$ as $M=A+iB$, where $A,B$ are real matrices. Now consider the correspondence $$f(A+iB)=\begin{pmatrix} A &amp; -B \\ B &amp; A\end{pmatrix}.$$  If $\det f(M)=|\det M|^2$ for square matrices, then we would have $GL(n,\mathbb C)\subseteq GL_+(2n,\mathbb R)$ with the identification $M\to f(M)$, which is an injective homomorphism. In other words, the complex general linear group would be a subgroup of the group of real matrices of twice the dimension and with positive determinant.  How is $\det f(M)=|\det M|^2$? Change Legend Right to Left Reading in QGIS I am a new QGIS user and i have a challenge to convert legend from right to left reading in QGIS like ArcGIS. Sum of $k$-th powers I've got two branches that are fully merged together. However, after the merge is done, I realise that one file has been messed up by the merge (someone else did an auto-format, gah), and it would just be easier to change to the new version in the other branch, and then reinsert my one line change after bringing it over into my branch. So what's the easiest way in Git to do this? How to hide title bar in Firefox 57 Quantum? I used to use an extension to hide/show the title bar in Firefox, but since Firefox 57 was released most of the extensions were disabled.  In Chrome I just uncheck the option "Use system title bar and borders" and it's done.  Are there any ways to do that? I want to define \ext to behave exactly like \lim.  I tried \newcommand{\ext}{{\mathrm{ext}}\,} but that doesn't behave exactly like \lim. Suggested reading for renormalization (not only in QFT) Forgotten the pattern and phone not showing the "forgot pattern" button. I upgraded my Moto G2 to Android Lollipop using over-the-air upgrade. It was awesome but I set a pattern lock which I forgot. Usually after 5 wrong attempts it shows the "forgot password" button but it is not showing that button even after 100 wrong attempts. How to unlock the phone? Suppose $k$ is a field, $A$ is a $k$-subalgebra of the polynomial ring $k[x]$. Must $A$ be a finitely generated $k$-algebra?   Thanks. $|a_{n+1}-a_n| \leq \frac{1}{2} |a_{n}-a_{n-1}|$. I'm trying to show that $(a_n)$ is convergent by showing that $(a_n)$ is Cauchy.  let $|a_2 - a_1 |  =x$.   $|a_3-a_2| \leq \frac{1}{2}x$  $|a_4-a_3| \leq \frac{1}{2}|a_3-a_2|\leq \frac{1}{4}x$  In general, for every $n$:  $|a_{n+1}-a_n| \le \frac {1}{2^{n-1}}x$  Let $\epsilon &gt;0$  for every $m,n &gt; 0 $, say $m&gt;n$ the following holds:  $$|a_m-a_n| = |a_m-a_{m-1} + a_{m-1} - a_{m-2} \dots a_{n+1}- a_n| \le$$  $$|a_m-a_{m-1}| + |a_{m-1} - a_{m-2}| + \dots |a_{n+1}-a_n| \leq \frac{x}{2^{m-2}} + \frac{x}{2^{m-3}} + \dots + \frac{x }{2^{n-1}}$$.  I can say that for big enough $n,m$, $|a_m-a_n|&lt;\epsilon$ and therefore, this sequence is Cauchy? It sounds not good enough to me yet I don't know what else to do here.
