On Interrogative Sentence
Is the question mark misused in affirmative sentences?
Elementary derivation of certian identites related to the Riemannian Zeta function and the Euler-Mascheroni Constant Is the proof of these identities possible, only using elementary differential and integral calculus? If it is, can anyone direct me to the proofs? ( or give a hint for the solution )  1)$$\int_0^\infty { e^{-x^2} \ln x }\,dx = -\tfrac14(\gamma+2 \ln 2) \sqrt{\pi} $$  2)$$\int_0^\infty { e^{-x} \ln^2 x }\,dx = \gamma^2 + \frac{\pi^2}{6} $$  3) $$\gamma = \int_0^1 \frac{1}{1+x} \sum_{n=1}^\infty x^{2^n-1} \, dx$$  and lastly,  4) $$\zeta(s) = \frac{e^{(\log(2\pi)-1-\gamma/2)s}}{2(s-1)\Gamma(1+s/2)} \prod_\rho \left(1 - \frac{s}{\rho} \right) e^{s/\rho}\!$$  I personally think the last is obtained from a simple use of the Weierstrass factorization theorem. I'm unsure as to what substitution is used.  $\gamma$ is the Euler-Mascheroni constant and $\zeta(s)$ is the Riemannian Zeta function.  Thanks in advance. Regex for splitting a string using space when not surrounded by single or double quotes Using notify-send with cron I am using Arch Linux with KDE/Awesome WM. I am trying to get  notify-send to work with cron.   I have tried setting DISPLAY/XAUTHORITY variables, and running notify-send with "sudo -u", all without result.  I am able to call notify-send interactively from the session and get notifications.  FWIW, the cron job is running fine which I verified by echoing stuff to a temporary file. It is just the "notify-send" that fails to work.  Code:  [matrix@morpheus ~]$ crontab -l * * * * *  /home/matrix/scripts/notify.sh  [matrix@morpheus ~]$ cat /home/matrix/scripts/notify.sh #!/bin/bash export DISPLAY=127.0.0.1:0.0 export XAUTHORITY=/home/matrix/.Xauthority echo "testing cron" &gt;/tmp/crontest sudo -u matrix /usr/bin/notify-send "hello" echo "now tested notify-send" &gt;&gt;/tmp/crontest  [matrix@morpheus ~]$ cat /tmp/crontest testing cron now tested notify-send  [matrix@morpheus ~]$    As you can see the echo before &amp; after notify-send worked. Also I have tried setting DISPLAY=:0.0   UPDATE: I searched a bit more and  needs to be set. And after hardcoding this using the value I got from my interactive session, the tiny little "hello" message started popping up on the screen every minute!   But the catch is this variable is not permanent per that post, so I'll have try the the named pipe solution suggested there.   [matrix@morpheus ~]$ cat scripts/notify.sh #!/bin/bash export DISPLAY=127.0.0.1:0.0 export XAUTHORITY=/home/matrix/.Xauthority export DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-BouFPQKgqg,guid=64b483d7678f2196e780849752e67d3c echo "testing cron" &gt;/tmp/crontest /usr/bin/notify-send "hello" echo "now tested notify-send" &gt;&gt;/tmp/crontest   Since cron doesn't seem to support notify-send (at least not directly) is there some other notification system that is more cron friendly that I can use? I've been to South Korea a few times already and always enjoy it but I've always had an onward ticket before.  Now I need to fly home from a trip that's lasted over a year, but I still want to take my time and keep my options open.  There's a good choice of cheap flights from Istanbul to Seoul and from Seoul I can't decide yet whether to fly straight home or take a ferry to China, hitchhike to Guangzhou, and get a cheap flight home from there.  I can't really just buy the China-Australia flight now because I'm not sure yet whether I'll be able to get the Chinese visa easily enough or how long my remaining money will last.  I know Korea, like most countries, has rules saying you need an onward ticket, but in my experience many countries never try to verify that you have this ticket unless you fit some profile. So in this instance I would find first-hand knowlegde much more informative that pointers to a government website.  In practice does South Korea admit tourists with one-way tickets? Add scratches to a material in Cycles? Automorphisms of the complex plane How can it be shown that $$Aut(\mathbb{C})=\{f|f(z)=az+b,a\neq 0\},$$ where an automorphism of $\mathbb{C}$ is defined as a bijective entire function with entire inverse?  If $f$ is of the form $f(z)=az+b$, with $a\neq 0$, then obviously $f$ is in $Aut(\mathbb{C})$. How can I prove the converse? Are upvotes on competing posts counted per question or per answer for Sportsmanship? The definition of the :     Up voted 100 competing answers   doesn't specify whether each upvote on competing answers to the same question counts towards this criteria, or if it's limited to one "point" per question no matter how many additional competing answers you upvote.

I have a dual boot on my computer of Windows 7 and Xubuntu 12.10. The Linux boot is 1st and the Windows 2nd. I would like to reverse the boot order in the GRUB menu. I need to know the steps to go about editing GRUB. I do most of my work on Windows and need it to be 1st so I can boot up and not watch it. Why is my ASCII art all wonky? Nothing looks right in the ASCII art.  It looks wrong and nothing is proportional, how do I fix this? I have tried fiddling with my font size, but nothing still looks right!

Active vs passive voice with inanimate object as the subject I have asked the  in ELL Stackexchange forum. There all the answers and comments I received was really helpful, but still I was looking for something more. So I have decided to ask this same question here also.   I have seen some sentences like this -         The film was announced to be released on this coming Friday.   The film was announced to release on this coming Friday.      Both the sentences are used, and I know they are interchangeable and does bear the same meaning. But I have some doubt about the second sentence - why is it "to release", when the film cant release itself.   Some other sentences of similar structure that arises my confusion -         The product sells well.   The book reads well.   The glass broke.      The sentences are understandable, but in each of the sentences the subjects can't perform any job, as they all are inanimate object. The verbs are active, but they acts like they are used as passive.  Now my question is how to decide which verb to use this way and which not? I have searched through the internet and in AskUbuntu, but I could not find a working solution for my little problem.  The RTL8723ae WLAN is behaving strangely on Ubuntu 14.04 and drops the WLAN connection constantly. I am using the notebook MSI GE40 and have already seen on the web that there are other people having the same problem but there was no permanent solution. The problem did not exists on the original Windows 8 on the device and the router is a TP-Link, which I can control (channel change and so on, I use WPA2-PSK WLAN security).
