Why is my UINavigtionController bar getting incorrectly positioned on iOS 7 only when I override it?
Navigation bar overlapped by status bar
Equaling 3 Displays Total (or 2, if the laptop display cannot be used).  I work at home on two large monitors, but at the office on a laptop with a single large monitor. Is it possible to attach two (or more?) external monitors to a laptop without having them clone each-others display?

Subgroups of $U(n)$ isomorphic to a direct sum of cyclic groups How we fix (La)TeX math coding to be left aligned In display math (employing $$...$$) content normally gets aligned centered. But, I need it to be left aligned. Any suggestions?  Example  $$f(x) = \frac{{{{\sin }^2}x{\mkern 1mu} \cos x}}{{\sin x + \cos x}} -          \frac{1}{4}\tan (\frac{\pi }{4} - x){\mkern 1mu} {\mkern 1mu}           \forall {\mkern 1mu} x \in R - \{ n\pi  - \frac{\pi }{4}\} ,n \in I$$ I have installed bootable ubuntu on hard disks but now I can not format them with Disk Utility program. When I try to format it says "One or more partitions are busy on /dev/sdb" for both hard disks. Is there any way to format these drives?  EDIT: With "Disk Utility" program when I select one of the hard drives It shows 3 volumes;  99 MB FAT 111 GB EXT4 9 GB UNKNOWN   I can not format this unknown volume.  With Gparted program, It doesn't shows Unknown volume only shows 111GB EXT4. A Linear Diophantine Equation is of the following form:                                                                                        $Ax+By+C=0$, where $x_1 \leq x \leq x_2$ and $y_1 \leq y \leq y_2$.  If the value of $A,B,C,x_1,x_2,y_1,y_2$ are given and $x_1 \leq x_2$ and $y_1 \leq y_2$, then how many solutions can be found? How can I find out the total number of solutions according to the above condition. Why is channel capacity a factor of bandwidth instead of frequency? I'm trying to understand the concept of capacity for a wireless channel.  Some help would be appreciated.  For a AWGN channel capacity is calculated as:  $$C=B \cdot log_2(1 + S/N)\text{ bits/sec}$$  B = bandwidth.  This is what I don't understand.  Why isn't it a factor of frequency? To me considering bandwidth only makes sense in cases where the system changes frequency.   Bandwidth is the difference between an upper and lower frequency range.  Well, what if I'm using a fixed-frequency signal?  Fupper and Flower would be the same value, right?  So does that mean B=0?  So a fixed frequency signal can't carry any data?  We know that's not true, AM radio does it.  So what am I missing? According to this formula, a fixed-frequency signal would have the same performance regardless of whether it's at high or low frequency.  This makes no sense to me.  For example say my bandwidth is 1Hz at a fixed frequency of 1Hz.  Compare this with a bandwidth of 1Hz at a frequency of 2.4GHz.  It's plainly obvious that I can cram way more bits into 2.4 x 109 cycles/second than I can with just 1/sec.  But according to this formula I can't.  Please help. What about fractional differences?  Waveforms are analog in nature, so we could have a 1Hz signal and a 1.5Hz signal.  Likewise at the high frequency range.  Say 2.4GHz minus 0.5Hz.  There is an infinite amount of space between 1 and 1.5.  Could not 1Hz and 1.001Hz serve as two separate channels?  In terms of practicality I realize this would be difficult, nearly impossible to measure this difference with modern electronics, especially with noise added, but in pure theory you could have two channels.  So in that sense, shouldn't there be an infinite amount of bandwidth between two frequencies?  Or do we only count in 1Hz whole number increments? Help removing subsection and subsubsection numbers from Table of Contents TOC Hello I am trying to further modify my TOC.  I got an answer  as to how I could remove the \section numbers on the left side of the TOC and now I would like to expand that.  I would like to remove the left-hand numbering for \subsection and \subsubsection as well but I do not know how.  (I also want to keep these numbers out of the document and I am using \def\sectionformat{} to do that)  Also, my TOC is slightly over one page and so I would like to adjust the spacing from 2 to 1.5,  is there any way to do this?    \documentclass[12pt, a4paper, twoside]{article}     \usepackage{baskervald}     \usepackage[margin=1in,bindingoffset=15.5mm,heightrounded]{geometry}     \usepackage[T1]{fontenc}     \usepackage[notes]{biblatex-chicago}     \usepackage{filecontents}     \usepackage{microtype}     \usepackage{url}     \usepackage{makeidx}     \usepackage{indentfirst}     \usepackage{setspace}     \usepackage{chngcntr}\counterwithin*{footnote}{section}     \newcommand*{\textsubscript}[1]{$#1{}$}     \DefineBibliographyStrings{english}{references = {Works Cited}}     \DeclareBibliographyCategory{primary}     \makeindex     \addbibresource{bibliography.bib}     \makeatletter     \let\latexl@section\l@section     \def\l@section#1#2{\begingroup\let\numberline\@gobble\latexl@section{#1}{#2}\endgroup}     \def\@seccntformat#1{\ifcsname #1format\endcsname\else\csname the#1\endcsname\quad\fi}     \def\sectionformat{}     \def\subsectionformat{}     \def\subsubsectionformat{}     \makeatother     \author{}     \title{\vspace*{36 pt}\textbf{\emph{\Huge{Big Important Title}}}\vfill}     \date{}     \begin{document}     \tableofcontents     \section{Part I}     Hello World     \end{document} Receiving commandline input while listening for connections in Python Spoilers from the Season 7 finale of Game of Thrones, "The Dragon and the Wolf".  In one of the final scenes, Jaime and Cersei are discussing Jaime's future with them, at which point       Cersei nods her head, signaling the kill order for 'The Mountain', yet 'The Mountain' pulled out his sword but why didn't he kill Jaime? I am currently writing an essay on artificial moral agents, and I need to explain the difference between ethics and morals. However, I am finding it really hard to find a good book or research paper which contains a citable definition.   Could someone point me in the right direction? so I am creating a few posts about bearings and wheels, (story so far):      I have now got the wheels, bearings and freehub working.  Started riding to work this morning and I almost couldn't stop at a junction.  Thankfully wasn't going too fast.  I physically can not get the wheel to lock.  I have to use both brakes at full force to get the bike to roll to a stop.  If I only use one brake I would not stop at any junction in time.  Could the cause be any of the following:   Over greased bearings? Over greased axle? not tightened cone hubs enough? not tighted axle enough?   I do not have any grease on the disk brakes them selves.  Rather nervous getting on the bike now.  Don't seem to be doing too well with this bike home fixing thing.  over greased bearings?  EDIT  Forgot to mention that it is hydraulic disk brakes.  EDIT 2  So in the end I took it to the LBS as I didn't have much confidence in my self at this point.  They had to replace the front pads but where able to clean the rear and cleaned the rotors.  (I had tried to clean the rotors but obviously not vigorously enough).  He said it was a bit of a pain to do.  All is working again.  They double checked my wheels and said I had put them back together correctly which is reassuring.  Thanks for all the help C++, array of objects without I run a guest ubuntu 12.04 on a host ubuntu 12.04, with VirtualBox, and the guest is much, much slower than the host (ALT+TAB takes 4-5 secs). I had a look around and I found contradicting opinions on VirtualBox versus VMware (free); so I thought to keep the former.   Both systems are updated, I installed the additions on the guest and I evenly split memory and video memory (64MB) between guest and host. I am running a Toshiba m200 laptop with 4GB ram and shared video memory. The host bios does not include a configuration option for machine virtualization. I have 2 cpus and I can't give them both to the virtual machine.  Is there anything I overlooked that could solve my problem?  Feel free to ask for more info, and thank you for any help.  EDIT Idling with the system monitor open the (single) guest cpu never gets below 55% and could rise to 80 - 90% just by moving the mouse around. Opening Firefox will cause the system monitor to show cpu usage 100% in the guest, while the host shows that both cpus are evenly working around 60%.  My cpu is Intel® Core™2 Duo CPU T5450 @ 1.66GHz × 2.  If this is not a configuration problem, does it mean my machine is too weak for virtualization? How is Cooper's age justified?

Activity Monitor in Mavericks "Show Memory Usage" dock icon gone? I just purchased a new MacBook Pro with Mavericks installed and noticed that Activity Monitor doesn't have the "Show Memory Usage" dock icon option anymore.  I really liked this option since I used it to prevent disk swapping by closing applications when I had too many open.  What gives? How can one derive Schrödinger equation?
