In Windows, you can run android application using BlueStack.   I was wondering, is there any way these apps can be run on Ubuntu 12.04?
Basically, I have a kindle fire that uses a form of the android OS and was wondering if there was a way I could run similar apps on my Ubuntu system. Specifically I'd like the news reader program "Pulse".  Anybody know if such an emulator or workaround exists?
Is it possible to adjust desktop monitor brightness like on laptops? Yes all desktop monitors have separate menu for it. But is it possible to change this to something like Winkey+(F1..F12)?    Monitor is connected via VGA or DVI cable.   OS: Ubuntu 14.04 Desktop monitors In SQL Server, how do I "floor" a DATETIME to the second/minute/hour/day/year?  Let's say that I have a date of 2008-09-17 12:56:53.430, then the output of flooring should be:   Year:  2008-01-01 00:00:00.000 Month: 2008-09-01 00:00:00.000 Day: 2008-09-17 00:00:00.000 Hour: 2008-09-17 12:00:00.000 Minute: 2008-09-17 12:56:00.000 Second: 2008-09-17 12:56:53.000 in a mountain climbing expeditions 5 men and 7 women are to walk in a mountain climbing expeditions 5 men and 7 women are to walk single file so that no 2 men are adjacent. How many ways are possible? Understanding the Basic Context of Trusted Hosts I got the trusted host settings error.      The trusted_host_patterns setting is not configured in settings.php. This can lead to security vulnerabilities. It is highly recommended that you configure this. See Protecting against HTTP HOST Header attacks for more information.    I read the  but I'm not understanding some of the basic context.   Are the "trusted hosts" me and other administrators who want to be able to administer the site remotely?  If so, would I add my PC's domain to the trusted host list? The best free and most up to date phylogenetic tree on the internet? I found phylogenetic tree in wikipedia is lacks of accuracy. It actually confusing with versions. Some terms was not scientifically accurate with dna analysis anymore  So are there anyone know where is the most updated datasource on the internet? Find all solutions to $x^9 \equiv 25 \pmod {29}$ Distribution of hitting time of line by Brownian motion I came across the following question:     Let $T_{a,b}$ denote the first hitting time of the line $a + bs$ by a standard Brownian   motion, where $a &gt; 0$ and $−\infty &lt b &lt \infty$ and let $T_a = T_{a,0}$ represent the first hitting time of the level $a$.      1) For $\theta &gt; 0$, by using the fact that $\mathbb{E}e^{-\theta T_a}=e^{-a\sqrt{2\theta}}$, or otherwise, derive an expression for $Ee^{-\theta T_{a,b}}$, for each $b$, $−\infty &lt b &lt \infty$.       2) Hence, or otherwise, show that, for $t &gt; 0$,    $$\mathbb{P}[T_{a,b}\leq t] = e^{-2ab}\phi\left(\frac{bt-a}{\sqrt{t}}\right)+1-\phi\left(\frac{a+bt}{\sqrt{t}}\right).$$   For the first part, I ended up, by changing measure, with the (unverified) expression  $$\mathbb{E}e^{-\theta T_{a,b}}=\exp\left(-a\left[b+\sqrt{2\left(\theta+\frac{b^2}{2}\right)}\right]\right).$$  What's the cleanest way to do the second part? It seems I could either do some kind of inverse transform on the moment generating function, or calculate the moment generating function of the given distribution. Both of these seem difficult. Am I missing something, or do I just need to persevere?  Thank you. When I search for my address on Google Maps it cannot be found which means I can't order takeaway etc.  Is there a way of adding my address to Google Maps or even add a street address?  I want the address to be publicly available so others can search it. Does iTunes Home Sharing transfer in-app purchases? My wife recently got an iPhone and, being that I'm an iPhone user already, I set up iTunes Home Sharing (under my Apple ID) so that I could share some of my purchased apps with her.  While paid apps transferred to her phone without a problem, in-app purchases that I had made under my account didn't transfer over.  Is this the correct behavior? Our phones are set up under different Apple IDs, but I was still able to transfer purchased (paid upfront) apps to her – which is completely allowed under the Terms of Use – so I assumed the same would apply to in-app purchases as well. Grub: reboot to specific kernel I'd like to ask for help getting grub-reboot to work.  The theory: According to  (and other sources) I should be able to choose the kernel for the next reboot, using grub-reboot. However, this does not work for me; grub always boots to the default kernel.  Here's what I tried:  $ grep GRUB_DEFAULT /etc/default/grub GRUB_DEFAULT=saved $ grep "menuentry " /boot/grub/grub.cfg  menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-43-generic' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-43-generic-advanced-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-43-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-43-generic-recovery-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-36-generic' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-36-generic-advanced-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-36-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-36-generic-recovery-f3a807d1-3fd6-4970-b741-5382e9801060' {  # Version 1, using the name $ sudo grub-reboot "Ubuntu, with Linux 4.4.0-36-generic"  # Version 2, using the id $ sudo grub-reboot gnulinux-4.4.0-36-generic-advanced-f3a807d1-3fd6-4970-b741-5382e9801060  # Version 3, counting $ sudo grub-reboot 3   Neither of these commands seem to have an effect; after reboot, I always end up with the 4.4.0-43 kernel.  Note: This is on Ubuntu 16.04 Xenial. It is a server machine and I don't have access to the console during boot, so I can't look at the grub menu :( Per the kernel documentation:  This control is used to define how aggressive the kernel will swap memory pages.  Higher values will increase aggressiveness, lower values decrease the amount of swap.   However this is kind of vague. I'm trying to figure out exactly what the parameter ultimately controls. I know it adjusts how aggressively the kernel tries to swap out pages, but what decision making process in the kernel code does it affect?  Does it adjust how long ago a page must have been accessed before the kernel swaps it out? If so what does the default value of 60 represent? And how much is changed by a increment/decrement of 1 (a formula would be nice)? Or does it swap out pages based on their access frequency? Or something else? Client should send one big packet or multiple smaller ones per frame? The client can do several actions per frame, for instance, requesting a movement, shooting etc. Should i send a packet to the server for each action the client performed during the frame, or should i stack them in an unique packet and send it at the end of the frame?  EDIT: i'm using Jmonkeyengine and the provided network API SpiderMonkey.

Is there a way to see my previous performances with respect to winter-bash? May be something like leagues for winter-bash? I understand that hats are different each year, but at least it would be nice to see the number of hats collected. Create 128 Barcodes within Excel Is there a way to create Barcodes (128 standard) on a Mac, preferably via an add-in?  I need it to create barcodes in Excel sheets (or moreso a friend of mine needs it).   I have tried all VBA macros and fonts I found on Google, but none give me a scannable result (usually there are weird characters like ó's mixed in). Does anybody have a working solution? multi-layer board copper pour I have a 6-layer board where the internal 4 planes are +15,GND,VCC,-15.  I was wondering if there was any advantage to doing a copper pour on the top and bottom layers?  I would probably leave them floating as I don't want to use micro-vias to say tie it to GND?    Is this actually a bad idea?  I.e. floating copper=antenna.  Would it be just as acceptable to have 4 layer board with the top layer having copper pour to VCC and the bottom having a pour to GND and keep the two internals as +-15?  Note that this is for a fairly low speed circuit which has some analog and digital parts. Coming from SketchUp one of the tools I miss most is the circle draw tool which lets you draw a circle on any face and then you could extrude it in/out. The only tool that I know of that comes close to this is the knife tool but this would be very impractical to cut out with the knife  Example:    Is there any tool in blender that can match this function? also how could you do this with squares? alias or bash function does not work When I create  alias wd='ps -ef | grep java | awk {'print $2 " " $9'} | egrep "(A|B|C|D)"'   or  function wd () {     ps -ef | grep java | awk '{print $2}' ... }   in my .bashrc file, I get errors.  Interestingly, if I source my .bashrc file with the function, it 'compiles', but when executing, gives me:   context is      &gt;&gt;&gt; \ &lt;&lt;&lt; {\print     missing }   Can someone help me with this, and also answer when its better to put something in a function versus in an alias? Sum of two squares modulo p Using only the delta definition of a limit, how can we prove that the sequence $\{a_n\}$, where $a_n = \sin n$, as $n$ tends to infinity does not have a limit?  Thanks!
