How to prove that a vector field over the torus is diferenciable?. <p>I was dealing with a question that for me seems vague, surely because I'm starting in differential geometry. Well:</p>
<blockquote>
<p>One vector field of the torus <span class="math-container">$T$</span> is obtained by parametrization of the meridian by arc lenght e defining <span class="math-container">$w(p)$</span> as the velocity of meridian by <span class="math-container">$p$</span>. Prove that the field is diferenciable.</p>
</blockquote>
<p>Well, I am confused because maybe there's more than one parametrization... I could not understand how to approach can run in general.</p>
<p>Many thanks!</p>

How do I bring an application running in the background to the foreground in Linux without the commands fg or nohup?. <p>Due to habits formed over the years, I tend to click on the "x" icon in a Skype session running on Windows to minimize it however when I do the same on Linux Mint 11, it is sent to the background and there doesn't appear to be a way to bring it back to the foreground without me killing the running instance. Is there a better way?</p>
<p><strong>EDIT 0</strong></p>
<p>When I run the command <code>nohup skype &</code>, it seems brings Skype back to the foreground however am logged out. I am then unable to log back in without killing the process. The command <code>fg %processid</code> seems to be limited to jobs</p>

<p>I am running Linux Mint 11, with Gnome 2. I believe the window manager is Metacity.</p>

Improve coding quality. <p>I have been dealing with programming for several years now (I am still a student but with a lot of internships). Mostly working with C++, Python and MATLAB, I noticed that whenever I download an SDK or a library from Internet/GitHub and look inside, the code is much more complex than mine, using error catches everywhere and other things that would never come to my mind while writing my own code. My question is, how can I learn or practice this kind of things? From my experience, no programming course talked about coding style, when and how to use try/catch efficiently, how to debug faster etc... I am also not thinking about using mutex while accessing one variable from different functions at the same time because my code is simply working without them and I didn't face any problem until now.</p>
<p>Currently I am working on a project using Python and Pycharm is helping me a lot keeping a correct coding style but it is limited to the syntax and naming conventions.</p>

How do I use MATLAB to solve an Euler Backward problem for a Differential Equation?. <p>Is there a way to use MATLAB to solve an Euler Backward problem when the function I have is a differential equation? </p>
<p>My original problem was to simulate an electromagnetic and an electrical field for a certain interval in R^2 and in this interval an electron would enter with an initial speed in x, y direction. I then plotted the path the electron would take inside the field, but now I'm trying to approximate the path using Euler Backward.</p>
<p>Our differential equation in MATLAB looks like this:</p>
<pre><code>dy(1)=y(3);
dy(2)=y(4);
dy(3)=y(4)+1;
dy(4)=-y(3)
</code></pre>
<p>Where y=[x ; y ; u ; v] where u is the derivative of x and v is that of y.</p>

MAC spoofing preventing connection. <p>I'm attempting MAC spoofing on a network I own. I'm connecting to a NETGEAR WNDR4300 wireless router from an Ubuntu Linux machine. The network uses WPA2-PSK [AES] security.</p>
<p>Connecting to the network with an un-spoofed MAC works fine. I can bring my network interface down with</p>
<pre><code>sudo ip link set dev wlan1 down
</code></pre>
<p>and then spoof my MAC with either</p>
<pre><code>sudo macchanger -e wlan1
</code></pre>
<p>or manually with</p>
<pre><code>sudo ip link set dev wlan1 address XX:XX:XX:XX:XX:XX
</code></pre>
<p>(picking some address). Both techniques work. When I bring the interface up with</p>
<pre><code>sudo ip link set dev wlan1 up
</code></pre>
<p>it attempts to reconnect to the network, then prompts me for the password. I enter the correct password, but it fails to connect. I've tried this numerous times, with various MACs (random, same vendor, etc.), without success.</p>
<p>What's going wrong, or how can I diagnose the issue?</p>

Iptables exception for specific port. <p>I'm new to iptables but configured a simple natting today on my raspian:</p>
<pre><code># Always accept loopback traffic
/sbin/iptables -A INPUT -i lo -j ACCEPT
# Allow established connections, and those not coming from the outside
/sbin/iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
/sbin/iptables -A INPUT -m state --state NEW -i tun0 -j ACCEPT
/sbin/iptables -A FORWARD -i tun0 -o eth2 -m state --state ESTABLISHED,RELATED -j ACCEPT
# Allow outgoing connections from the LAN side.
/sbin/iptables -A FORWARD -i eth2 -o tun0 -j ACCEPT
# Masquerade.
/sbin/iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE
# Don't forward from the outside to the inside.
/sbin/iptables -A FORWARD -i tun0 -o tun0 -j REJECT
# Enable routing.
echo 1 > /proc/sys/net/ipv4/ip_forward
</code></pre>
<p>So as you can see I also use openvpn and redirect the traffic to the tunnel interface.
I'd like to create an exception for example for the port range 900 to 999 and source 192.168.1.5 to be excluded and sent directly to interface eth1 and avoid the vpn encryption.</p>
<p>How can I create such a rule?</p>
<p>Thanks a lot for your input.</p>
<p>EDIT: I tried something like</p>
<pre><code>iptables -t nat -A POSTROUTING -p tcp --dport 900:999 --out-interface eth1 -j MASQUERADE
</code></pre>
<p>But it doesn't seem to have the expected effect...</p>

Someone recommended "The Summer That Melted Everything" on here, I just finished it and thought it was incredible, definitely a summer must-read.. This felt like a book that should be recommended to read in classes, it felt like one of those books that's so influential and does such a great job with it's storytelling that it felt like something that altered my perspectives on a lot of things.
The book is beautifully written, I found myself highlighting more sentences in this book than in any other book in years. I was surprised to see the author doesn't have any other books written yet as this one seemed so well-written. I haven't heard much about this book but I think it deserves more attention. I laughed, cried and audibly gasped while reading it.
I hope this convinces others to read it as it's such a great read, and thank you to whoever recommended it! | 0non-cybersec

HP CP5225 print colour with Windows 7 64-bit drivers. <p>According to the HP website, the following operating systems are supported:</p>
<blockquote>
<p>Compatible operating systems</p>
<ul>
<li>Microsoft® Windows® 2000</li>
<li>XP Home</li>
<li>XP Professional</li>

<li>Windows Vista®</li>
<li>Windows® 7 (HP UPD only)</li>
<li>Mac OS X v10.3, v10.4 or higher</li>
</ul>
</blockquote>
<p>Our client purchased HP CP5225 printers less than a year ago and used it successfully with Windows XP 32-bit and Vista 32-bit clients. Note that this model only connects via USB and has no networking capability.</p>
<p>Following HP's instructions, we set up new Windows 7 64-bit clients using the HP UPD (Universal Printer Driver). This works, but does not allow for colour printing. Specifically the "<em>Color</em>" tab is not present under "<em>Printing Prefrences</em>" allowing monochrome printing only.</p>
<p>HP's support call centre only advises to reinstall the driver. I've tried cycling through the PCL and PostScript options, but to no avail.</p>
<p>We have also tested the following with negative results:</p>
<ol>
<li><p>Running <em>Printer Properties</em> -> <em>Device Settings</em> -> <em>Automatic Configuration</em> -> <strong>Update Now</strong> detects the printer, but returns the following message "<em>The device 'HP_PCL6_x64_UDP_Traditional' may not be able to print this document. Communication with the device could not be established to verify this is a supported device. Would you like to use this device anyway?</em>"
Selecting <em>Yes</em> and checking <em>Printing Preferences</em> before and after a reboot confirms no Color tab is present.</p></li>
<li><p>Enabling and disabling Duplexing makes no difference as some on the web suggested.</p></li>
</ol>
<p>If you know of any solutions or workarounds specific to an HP colour printing issue with the HP UPD via USB on Windows 7 64-bit, please share your findings or suggested solution to the above problem.</p>

<p>I have searched a lot for this type of a command or script, but I haven't found any yet. Has anyone found something like this?</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:

[DISCUSSION] Travis Scott- Days Before Rodeo (Five Years Later). Days Before Rodeo was Travis Scott’s second mixtape release, and it’s now been 5 years since it came out. In my opinion, it’s one of the greatest mixtapes of the current generation and really was the steeping stone for the Travis that we saw on Rodeo, How do you guys think it compares to the rest of the discography as well as your general opinion on it? | 0non-cybersec

Bought smaller clothes than I've ever bought since high school today.. All the pants I own have either a 40" or 38" waist, and all my shirts are XL. When I began this journey the 40" pants fit a little snug, but doable, and my 38" pants were a forgotten dream of what once was, doomed to spend eternity at the bottom of my dresser.
At some point the 38" pants started to fit okay. Then the 40" pants were just way to big as to be comical, so I got rid of them. Today I went to get some jeans and a shirt, and I realized that my belt was the only thing really keeping my 38" pants up on my waist, so I tried out some 36" pants, and while I was at it tried a large shirt, because why not.
Well, the 36" pants fit perfectly now, and the large shirt is perfect as well. I don't remember ever wearing a large shirt, and I haven't had a 36" waist since high school, and that was back in the 90's.
I was 245 lbs when I started taking care of this problem. Now I'm 205, with a goal of about 180ish or so. Weight loss tools include getting rid of my car and cycling everywhere, and using My Fitness Pal to keep track of calorie intake. Currently eating about 1790 calories daily.
The wife called me "too sexy", and joking forbids me from wearing my new clothes in public where other women might see. I've got to admit, I'm really starting to like what I see. | 0non-cybersec

How to change color of a tab in Firefox Quantum?. <p>I'm trying to change the colour of one or more tabs (not necessarily the one that is currently selected). It need to be at least the bit where the tab title is displayed, not sure how it's called. </p>
<p><a href="https://i.stack.imgur.com/ZVxPH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZVxPH.png" alt="enter image description here"></a></p>
<p>The Pre-Quantum Firefox addons don't work any more, is there any other way to do it? The colour does not need to persistent be between sessions. By the way the goal in the end is to visibly group contiguous tabs. I want it to be easy to differentiate between the tab groups (I'm already using tree style etc. but I want the distinction in the tab bar as well).</p>

Where is `Google Speech API Key`?. <p>I was refering to <a href="http://mikepultz.com/2013/07/google-speech-api-full-duplex-php-version/" rel="noreferrer">this link</a> where it discuss about the Google Speech engine. It says that I have to get an API Key from google, to use the google speech engine they are discussing. In the link posted, they have shown an image of activating the Speech API Key.</p>
<p>However when I went to the <a href="https://code.google.com/apis/console/" rel="noreferrer">API Site</a> I can't find anything about <code>Speech API</code>.</p>
<p>Is there no more API keys for Speech API? Or else no need to use them? It is worth to understand that this speech API allows uploading <code>flac</code> files, which is quite different from others.</p>

Cocycles for right- and left- regular representations on $\ell_2(G)$. <p>Using the standard notation, let $\lambda_gf(x)=f(g^{-1}x)$ be the left regular representation and $\rho_gf(x)=f(xg)$ be the right regular one, acting on the space $V$ of complex-values functions on $G$.</p>
<p>Let $b:G\to \ell_2(G)$ be a cocycle for $\rho$; i.e., $b_g=\rho_g f-f\in \ell_2(G)$ for some $f\in V$ and every $g\in G$.</p>
<p>Question: Does $a_g=\lambda_g f-f$ belong to $\ell_2(G)$ for every $g\in G$?
If not, what is the "smallest" subspace $W$ of $V$, $\ell_2(G)\subseteq W\subseteq V$ for which this happens?</p>
<p>The most interesting case seems to be when $G$ is amenable.</p>
<p>Edit: The metric interpretation is the following. Take all $f\in V$ whose discrete gradient with respect to the left-invariant metric is $\ell_2$-summable. Then $W$ is the space consisting of gradients of these $f$, with respect to the right-invariant metric. </p>

Integrating $\sqrt{1-x^2}$ by interpreting it geometrically as an area within a circle. <p>For the integral $$\int \sqrt{1-x^2} dx = \frac{1}{2} \left ( \arcsin(x) + x \sqrt{1-x^2} \right)$$
Now it was explained to me that geometrically I could take part of the integral as an area sector and the other half a triangle. I am having a hard time seeing how I can even get a triangle as I am summing the rectangles.</p>
<p>How could you even see that the angle must be $\arcsin(x)$? </p>

Why are virtual machines on vSphere 5.0 suddenly suspended?. <p>We just got our vSphere 5.0 and vCenter Server 5.0 configuration working with several VMS.</p>
<p>These are the vms.</p>
<ol>
<li>Jenkins appliance.</li>
<li>vCenter Server Appliance</li>
<li>Windows7x64</li>
<li>Windows7x64-1</li>
<li>Windows7x64-2</li>
</ol>
<p>For some reason the Windows vms become unexpectedly suspended. To recover we simply power them back on it all is well until the next time. We found dcx some vmWare instructions to debug this via getting the log file from the vm. And here it is. But even with their hints..it's still unclear.</p>
<p>One important thing to notice in the log below is that this is only an portion of the file starting a few lines before where suspending started. So you can see the time stamp jumps 30 minutes because it ran fine for that long before it went suspended.</p>

Alternative to Source Insight. More of a code auditing issue than reverse engineering, but hopefully it does belong in here.
I'm looking for a tool that does the same job as Source Insight - source code analysis and browsing.
Key features-
* Parsing C/++ code.
* Jump-to-Definition, double-pane symbol under cursor preview, Symbol reference list.
* File content index pane (list all #define's, classes, methods, functions etc. by name).
Would've been nice:
* Ability to parse slightly-erroneous content.
* Contextual info pop-up.
* Runs on Linux.
* Still under active development (SI development seems to be limited to compatibility issues only).
The software really doesn't have to have any build/compilation or editing ability. Meant to be used as a viewer/browser only.
A bundle of plugins to Vim/Sublime Text that perform together the tasks above would be a great answer too. | 1cybersec

Can a MSSQL job change its own active schedule?. <p>I am planning a new job for MSSQL Sever 2016.</p>
<p>I'd like the job to run on Sunday, every 10 minutes, until it sees a confirmation record is added to a table it checks as the final step in the job. If the record is there, the job modifies its current schedule so it will not run again until next Sunday. This leads me to wonder when the schedule updates in a "natural" job cycle. I wonder if my change would be overwritten before it could be used.</p>
<p>So, can I use msdb.dbo.sp_update_jobschedule in a job's final step to do this to the current job and what technical pitfalls might I encounter doing that? </p>
<p>Examples and/or alternate solutions are always welcomed.</p>

Increasing accuracy of solution of transcendental equation. <p>I have a specific kinematics as a part of a more complex machine and need to compute some physical parameters that are <strong>very hard</strong> (more like impossible) to measure with proper <strong>accuracy</strong> with instruments I have at my disposal</p>
<p><strong>[kinematics]</strong></p>
<p><img src="https://i.stack.imgur.com/XtSXq.png" alt="enter image description here"></p>
<p>At first look it is a simple <code>1</code> degree of freedom arm (black) which can rotate around <code>x</code> axis. It has a weight to force it to go always up until it hit the mechanic endpoint (angle <code>a0</code>) or some tube (blue) with radius <code>r0</code>. Arm rotation center is at <code>y0</code>. The tube can be moved to any <code>y(t)</code> height.</p>
<p><strong>[usage]</strong></p>
<p>This is used to measure the radius of a tube for further processing. The radius can be computed (by basic goniometry) which leads to equation in the bottom of image. The constants <code>a0,y0,z0</code> are very hard to measure (it is inside complex machinery) so the measurement accuracy for distances is min <code>0.1 mm</code> and angle <code>0.1 deg</code> and even that is questionable.</p>
<p><strong>[calibration]</strong></p>
<p>So I decided to try compute these parameters from set of measurements done by the machine itself (auto-calibration). So I have calibration tube with known radius <code>r0</code>. All green parameters can be handled as constants. Now I position the tube along <code>y</code> axis to cover as much angles of arm as I could. Sadly the range is only about <code>20 degrees</code> (for current machine setup) remembering measured <code>a(t)</code> for preset <code>y(t)</code> ... as <code>n</code> point dataset. This gives me system of <code>n</code> transcendent equations. From this I try/guess "all" possibilities of <code>a0,y0,z0</code> remembering the best solution (closest to <code>r0</code>)</p>
<p><strong>[approximation of a0,y0,z0]</strong></p>
<p>approximation is based on this class of mine:</p>
<pre><code>//---------------------------------------------------------------------------
class approx
{
public:
double a,aa,a0,a1,da,*e,e0;
int i,n;
bool done,stop;
approx() { a=0.0; aa=0.0; a0=0.0; a1=1.0; da=0.1; e=NULL; e0=NULL; i=0; n=5; done=true; }
approx(approx& a) { *this=a; }
~approx() {}
approx* operator = (const approx *a) { *this=*a; return this; }
//approx* operator = (const approx &a) { ...copy... return this; }
void init(double _a0,double _a1,double _da,int _n,double *_e)
{
if (_a0<=_a1) { a0=_a0; a1=_a1; }
else { a0=_a1; a1=_a0; }
da=fabs(_da);
n =_n ;
e =_e ;
e0=-1.0;
i=0; a=a0; aa=a0;
done=false; stop=false;
}
void step()
{
if ((e0<0.0)||(e0>*e)) { e0=*e; aa=a; } // better solution
if (stop) // increase accuracy
{
i++; if (i>=n) { done=true; a=aa; return; } // final solution
a0=aa-fabs(da);
a1=aa+fabs(da);
a=a0; da*=0.1;
a0+=da; a1-=da;
stop=false;
}
else{
a+=da; if (a>a1) { a=a1; stop=true; } // next point
}
}
};
//---------------------------------------------------------------------------
</code></pre>
<p>It search the full range of single variable by some initial step then find the min deviation point. After that change the range and step to close area of this point and recursively increase accuracy.</p>
<p>The solution itself looks like this:</p>
<pre><code>// (global) input data
#define _irc_calib_n 100
#define _irc_approx_n 5
int irc_calib_ix; // number of measured points
double irc_calib_y[_irc_calib_n]; // y(t)
double irc_calib_a[_irc_calib_n]; // a(t)
double irc_calib_r; // calibration tube radius + arm radius
// approximation
int ix=0;
double e,a,deg=M_PI/180.0;
approx aa,ay,az;
// min max step recursions ErrorOfSolutionVariable
for (aa.init(-90.0*deg,+90.0*deg,10.0*deg,_irc_approx_n,&e);!aa.done;aa.step())
for (ay.init( 0.0 ,200.0 ,10.0 ,_irc_approx_n,&e);!ay.done;ay.step())
for (az.init( 50.0 ,400.0 ,10.0 ,_irc_approx_n,&e);!az.done;az.step())
{
for (e=0.0,ix=0;ix<_irc_calib_n;ix++) // test all measured points (e is cumulative error)
{
a=irc_calib_a[ix]+aa.a;
if (a> pi) a-=pi2;
if (a<-pi) a+=pi2;
if (fabs(a)>0.5*pi) { e=100.0; break; } // ignore too far angles
e+=fabs(+(cos(a)*(irc_calib_y[ix]-ay.a))
-(sin(a)*(az.a))
-(irc_calib_r));
}
}
// here aa.a,ay.a,az.a holds the result
</code></pre>
<p>This leads to solution close to the measured values but inside simulation the result is still not accurate enough. It is from 0.1 mm to 0.5 mm depending on number of points and angle range. If I measure properly <code>z0</code> and ignore its approximation then the precision is boosted significantly leaving <code>y0</code> without error (in simulation) and <code>a0</code> with error around 0.3 degree</p>
<p><strong>Q1 how can I further improve accuracy of the solution?</strong></p>
<p>I cannot increase the angular range. The number of points is best around <code>100</code> the more the better accuracy but above 150 the result is unstable (for some radiuses it is completely off). Have absolutely no clue why. The recursions number above <code>6</code> has not much effect </p>
<p>Could help weighting the deviations according to angular distance from <code>0 degree</code> ? But sadly <code>a(t)</code> range does not necessarily include <code>0 degrees</code></p>
<p>desired accuracy is <code>0.01 mm</code> for <code>y0,z0</code> and <code>0.01 degree</code> for <code>a0</code></p>
<p><strong>Q2 is there something I have missed?</strong></p>
<p>Like wrongly nested approximations or some math simplification or different approach</p>
<p><strong>[notes]</strong></p>
<p>The angle must be in form of <code>a(t)+a0</code> because it is measured by IRC with SW reset (<code>16000 steps/round</code>). It is reseted when in <code>a0</code> position I do not count vibrations and calibration tube eccentricity they are taken care of already and my first goal is to make this work in simulation without them. Tube <code>y(t)</code> can be positioned at free will and the <code>a(t)</code> measurement can be done at will. </p>
<p>Right now the calibration process scan points along <code>y</code> axis (movement from <code>a0</code> down). Computation with <code>6</code> recursions take around <code>35</code> seconds (so be patient). <code>5</code> recursions take around <code>22</code> seconds</p>
<p><strong>[edit1] here how the simulation is done</strong></p>
<pre><code>approx aa; double e;
for (aa.init(-90.0*deg,+90.0*deg,10.0*deg,6,&e);!aa.done;aa.step())
e=fabs(+(cos(aa.a)*(y(t)-y0))
-(sin(aa.a)*(z0))
-(irc_calib_r));
if (aa.a<a0) aa.a=a0;
</code></pre>
<p><strong>[edit2] some values</strong></p>
<p>Just realized that I had only <code>4</code> recursions in simulation code to match the input IRC accuracy then there must be <code>6</code> recursions. After changing it (also in previous edit) here are some results</p>
<pre><code> | a0[deg]| y0[mm] | z0[mm] |
simulated | -7.4510|191.2590|225.9000|
z0 known | -7.4441|191.1433|225.9000|
z0 unknown | -7.6340|191.8074|225.4971|
</code></pre>
<p>So the accuracy with <code>z0</code> measured is almost in desired range but with <code>z0</code> unknown the error is still <code>~10</code> times bigger then needed. Increasing simulation accuracy has no effect above <code>6</code> recursions and also no sense because real input data will not be more accurate either.</p>
<p>Here the simulated/measured points for testing with above simulated settings:</p>

<p><strong>[edit3] progress update</strong></p>
<p><strong>some clarification for @Ben</strong></p>
<p><strong>how it works</strong></p>
<p>the colored equation under the first image gives you the radius <code>r0</code> it is made from 2 joined <code>90 degree</code> triangles (basic trigonometry)</p>
<p><strong>red stuff:</strong></p>
<ul>
<li><code>y(t)</code> is motor position and it is known</li>
<li><code>a(t)</code> is IRC state also known</li>
</ul>
<p><strong>green stuff:</strong></p>
<ul>
<li><code>a0,y0,z0</code> are mechanical dimensions and are known but not precise so I measure many <code>a(t)</code> for different positions of <code>y(t)</code> with known calibration tube <code>r0</code> and compute the <code>a0,y0,z0</code> with higher precision from it</li>
</ul>
<p><strong>further accuracy improvement</strong></p>
<p>I actually managed to get it more precise by measuring <code>y1=y0+z0*cos(a0)</code> from special calibration movement with precision around <code>0.03 mm</code> and better. It is the height of intersection between arm in <code>a0</code> position and tube <code>y</code> movement axis. It is measured and interpolated from situation when arm get first time contact when tube coming from up to down but the real position must be recomputed by used radius and <code>a0</code>... because contact point is not on this axis ... (unless <code>r0=0.0</code>). This also eliminates one approximation loop from calibration because <code>y1,a0,z0</code> are dependent and can be computed from each other. Also removing double aliasing from measurement of IRC due to discontinuous manner of measurement and <code>a(t),y(t)</code> positions helped a lot to increase precision and computation stability (on real machine). I can not reliably asses accuracy right now because by analysis of many measured cycles I found some mechanical problems on the machine so I wait until it is repaired. Anyway the calibration vs. simulation accuracy for <code>r0=80.03 mm</code> with accounting both approaches and <code>_irc_calib_n=30</code> is now:</p>
<pre><code> ; computed simulated |delta|
a0= -6.915840 ; -6.916710 +0.000870 deg
y0=+186.009765 ;+186.012822 +0.003057 mm
y1=+158.342452 ;+158.342187 +0.000264 mm
z0=+228.102470 ;+228.100000 +0.002470 mm
</code></pre>
<p>The bigger the calibration <code>r0</code> the less accuracy (due to more limited <code>a(t)</code> range) this is by computing all <code>a0,y0,(y1),z1</code> nothing is measured directly or known. This is already acceptable but as I wrote before need to check on machine when it is ready. Just to be complete here is how simulated measurements looks like now:</p>

How to use spot instance with amazon elastic beanstalk?. <p>I have one infra that use amazon elastic beanstalk to deploy my application.
I need to scale my app adding some spot instances that EB do not support.</p>
<p>So I create a second autoscaling from a launch configuration with spot instances.
The autoscaling use the same load balancer created by beanstalk.</p>
<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:

Derivation Gaussian Mixture Models log-Likelihood. <p>I'm trying to understand the derivation of the log-likelihood function for Gaussian Mixture Models. According to my records the following steps are made.</p>
<p>The log-likelihood function is defined as:</p>
<p>$
L(X|\Theta) = \sum_{n=1}^N ln P(x_n|\Theta) = \sum_{n=1}^N ln \sum^M_{m=1} \alpha_m \mathcal{N}(x_n|\mu_m, \Sigma_m)
$</p>
<p>And then the partial derivative w.r.t. $\mu_m$ is made, where the first step seems fine for me, applying the chain rule and the derivative of the log:</p>
<p>$$
\frac{\partial ln P(X|\theta)}{\partial \mu_m} = \sum_{n=1}^N \frac{1}{\sum_{m'=1}^M\alpha_{m'} \mathcal{N}(x_n|\mu_{m'},\Sigma_{m'})} \cdot \frac{\partial \sum^M_{m=1} \alpha_m \mathcal{N}(x_n|\mu_m, \Sigma_m)}{\partial\mu_m}
$$</p>
<p>I just don't get how the prior equation leads to the following: </p>
<p>$$
\frac{\partial ln P(X|\theta)}{\partial \mu_m} =
\sum_{n=1}^N \frac{\alpha_m \mathcal{N}(x_n|\mu_n, \Sigma_m)}{\sum_{m'=1}^M\alpha_{m'} \mathcal{N}(x_n|\mu_{m'},\Sigma_{m'})} \cdot
\frac{\partial[ln(\alpha_m) + ln \mathcal{N}(x_n|\mu_m, \Sigma_m)]}{\partial\mu_m}
$$</p>
<p>From where does the log arises here again after the derivation?</p>

My SO cut his hair off and I hate it. [Remorse]: If you feel bad
When I met my SO, he had really long hair. We used to joke about him being "Rapunzel" etc, it was cute, then he cut it a bit shorter (so like just below the ears) and it looked SUPER hot. He's such an attractive guy, the combination of his sexy jawline and manly stubble and hot body and sexy tousled hair just drove me mad.
Today I came home and he's got this retarded looking short "posh guy" haircut, clean shaven, and doesn't even look like himself. I hate it. His reasoning was that he works outdoors and the extra 5 or so inches of hair made him too hot. Fair enough.
I just hate his haircut. I just jokingly told him he could star in a BBC miniseries and have started calling him "Mr Darcy" to try and lighten the mood and not make it obvious how unattracted I am to him right now. I'm taking the piss but deep down I really really can't stand the look he has now.
I don't know why I am so upset by this. Yes, his old hairstyle looked better. I might be PMSing or something but I just feel like he did this behind my back. If I came home with a shaved head I'm sure he would be "allowed" to not be attracted to me.
Either way, I feel bad. It's his hair, his body, I wish I wasn't being so shallow. | 0non-cybersec

Let continuous $T:X\to Y$ with $(X,||.||)$ and $(Y,||.||')$ normed spaces.Is it always true that $T(Bx)=By$?. <p>I am looking for a case where you have continuous <span class="math-container">$T:X\to Y$</span> where <span class="math-container">$T(Bx)$</span> is something else than a open (or closed) ball or even sphere (<span class="math-container">$Bx$</span> is the closed ball of <span class="math-container">$X$</span> with centre 0 and radius 1). If you have an isometry I think that is true to say <span class="math-container">$T(Bx)=By$</span> (where <span class="math-container">$By$</span> is the closed ball of <span class="math-container">$Y$</span> with centre 0 and radius 1) but if not I guess that you can see different things on <span class="math-container">$T(Bx)$</span>.

What is the operations order of these two functions. <p>I was writing a function to calculate the volume of a sphere when I encounter a problem and I don't know why if I change 4/3 * PI to PI * 4/3 I got different result.
What is the order of evaluation, if I use parenthesis like (4/3) * PI and PI * (4/3) I got the wrong answer in both cases.</p>
<pre><code>#define PI 3.141592
float Volume(int radius){
return (4/3 * PI * pow(radius, 3));
}
float Volume(int radius){
return (PI * 4/3 * pow(radius, 3)); //the good one

YSK the vast majority of gun owners and industry professionals also find carrying your rifle, or any long gun, in public places because "it's perfectly legal", in poor taste.. The practice of carrying a rifle into public to protest for your gun rights is not only detrimental to the movement, but it also paints gun owners and firearm enthusiasts as ignorant children. Doing this sours opinions and creates bad press.
Most gun owners see it this way. Every professional in the firearms industry I've talked to see it this way.
There are other ways to express your rights and protest without causing unnecessary fear.
People who openly carry rifles in public are a small minority of gun owners looking for attention or baiting police or baiting the public.
Dressing up in your best army surplus, or completely mall ninja tactikool gear and carrying your AR15 into a Denny's, so you can scare people, and be a dick to the cop who is just trying to figure out what's going on doesn't make you a protester or a patriot. It makes you an asshole.
On behalf of gun owners everywhere. We get it too. Most of us aren't like them.

Facing quality issues. <p>A workforce management software has complex GUI (for example values in a page depends on the status (closed or open) of other pages). Only latest and near past development has test coverage. During our last release, we received lots of bugs from customer in-spite of 2 weeks of testing Sprint. We don't have dedicated test team. The developers does the unit test and User acceptance test. Every day triggers automated regression test.</p>
<p>I am afraid the developers are not testing the entire workflow because its time consuming also not able to automate it because of its complexity. Any suggestions? The legacy code (15 years of development) has less code coverage. How can I improve quality?</p>
<p>Note: Now not possible to hire testers to have independent test team.</p>

Boyfriend of almost 2 years is having his ex-girlfriend move in with him.. advice please.. Ok Reddit, to keep it short and sweet.. I (27 female) was recently informed that my boyfriend (28 male) of 2 years is planning on having his ex-girlfriend (who he dated for 6 or 7 years) move in with him. From what I was told, he has known about this for almost 2 weeks now and has yet had the balls to tell me. Today while I was at work he sent me a text saying "we needed to have a little chat - and it's not going to be something you're going to be happy about but I'm sick of being broke". We still have not had this conversation yet since I worked 12 hours today and really just want sleep right now, and definitely don't want to have this conversation anyway other then in person.. so he said we'll talk about it tomorrow.
To add fuel to the fire, very early on in our relationship he actually cheated on me with this particular ex.. though he still denies it, I know there are pictures that exist of them making out that was taken while we were together. He has sworn up and down the past 2 years that this ex is nothing more then a really good friend (who supposedly has a boyfriend right now) and me not wanting to be the controlling girlfriend.. has sucked it up as best as I have been able to and kept my feelings (for the most part) to myself. But this.. this is a whole new level that I am 95% positive I cannot be comfortable with. So.. reddit.. what do I do? Am I wrong for considering ending it? He's one of the most stubborn people I've ever met and I know he will not back down from this decision, but I don't think I can live with him living with his ex-girlfriend.
Advice always greatly greatly appreciated.
**UPDATE** Wow.. never expected this many comments.. and this may be the first time in the history of reddit where every single person agrees to one answer. As one of you stated so greatly - I think I know what I need to do. I'm going to meet with him now.. bottle of wine in tow.. if you all are interested I will post an update to how it all goes down.
More importantly - thank you all from the bottom of my heart - sometimes we humans need a good kick in the ass to wake up - so sincerely, thank you. | 0non-cybersec

Is it possible to switch between multiple legends when switching between base groups?. <p>I am visualizing some vector data using leaflet in r which has multiple non-spatial variables that a user might be interested in. I want to allow the user to select one variable that will determine the color of the features. I accomplish this with the <code>baseGroups</code> argument to the <code>addLayersControl</code> function, where each group is the same data with a different color palette. This works fine for switching the colors of the features themselves, but does not allow me to switch between legends- every legend I add is always shown, even if I use the appropriate <code>group</code> within <code>addLegend</code>. See the example code and screenshot below:</p>
<pre><code>data <- data.frame(long = c(-93.2, -93, -93.5), lat = c(44.9, 45, 44.9),
var1 = c(1,2,3), var2 = c(10, 9, 1))
pal1 <- colorNumeric(palette = "Blues", domain = data$var1)
pal2 <- colorNumeric(palette = "Reds", domain = data$var2)
leaflet(data) %>%
addCircleMarkers(color = ~pal1(var1), group = "var1") %>%
addCircleMarkers(color = ~pal2(var2), group = "var2") %>%
addLegend(pal = pal1, values = ~var1, group = "var1") %>%
addLegend(pal = pal2, values = ~var2, group = "var2") %>%
addLayersControl(baseGroups = c("var1", "var2"), position = "topleft")
</code></pre>
<p><a href="https://i.stack.imgur.com/Q4Qja.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Q4Qja.png" alt=""></a></p>
<p>If I replace <code>baseGroups</code> with <code>overlayGroups</code> in my layers control, this works as expected, and only the legends for the selected groups are shown. However, this option isn't ideal because I don't want the user to be able to select multiple groups or deselect all groups.</p>
<p><a href="https://i.stack.imgur.com/8D6Tz.png" rel="noreferrer"><img src="https://i.stack.imgur.com/8D6Tz.png" alt="enter image description here"></a></p>
<p><a href="https://stackoverflow.com/questions/50641092/r-leaflet-map-change-legends-based-on-selected-layer-group">These</a> <a href="https://stackoverflow.com/questions/40770641/how-to-hide-toggle-legends-based-on-addlayercontrol-in-leaflet-for-r">questions</a> are quite similar to mine, but the accepted solutions both use <code>overlayGroups</code>, while I want to stick with <code>baseGroups</code>. I'm also hoping to avoid using shiny, if possible.</p>

stdin redirection for the script that asks for the input. <p>I'm trying to get the script that asks for the input to work when stdin is redirected. It could be that this is not even possible, but I would like to understand why. Here is an example:</p>

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'answer' is not defined

<p>I know I can get it to work with this:</p>
<pre><code>$ python <(echo 'q = raw_input("question ?"); print "\ngot: ", q') < <(echo answer)
question ?
got: answer

<p>but this is a process substitution. Is it possible to get it to work only with redirection?</p>

Designing Helm charts for microservices based application. <p>I'm currently building an application that is composed of 4 microservices (a, b, c, d). We would like to make Kubernetes Helm part of our CI/CD pipeline. </p>
<p>We are at the point where we're discussing how best to define the charts and was wondering was the advice from the community.</p>
<p>Our current options appear to be:</p>
<ol>
<li>a chart per microservice (so 4 charts)</li>
<li>a chart per "application flow" (service a calls b, service c calls d, so 2 charts in total)</li>
<li>a single chart that deploys all 4 microservices</li>
<li>some combination of 1. and 3. where we leverage the dependencies feature of Helm</li>
</ol>
<p>It might be worth calling out that:</p>
<ul>
<li>we currently don't have a requirement to deploy any microservice in isolation e.g. make it available to a separate application. </li>
<li>it is likely that we will need to have the ability to scale any microservice independently i.e. not simply replicate all 4 services.</li>
</ul>
<p>I'm mentioning these requirements because I feel that they may be relevant to the chart design.</p>

Stopping a Running Spark Application. <p>I'm running a Spark cluster in standalone mode.</p>
<p>I've submitted a Spark application in cluster mode using options:</p>
<pre><code>--deploy-mode cluster –supervise
</code></pre>
<p>So that the job is fault tolerant.</p>
<p>Now I need to keep the cluster running but stop the application from running.</p>
<p>Things I have tried:</p>
<ul>
<li>Stopping the cluster and restarting it. But the application resumes
execution when I do that.</li>
<li>Used Kill -9 of a daemon named DriverWrapper but the job resumes again after that. </li>
<li>I've also removed temporary files and directories and restarted the cluster but the job resumes again.</li>
</ul>
<p>So the running application is really fault tolerant.</p>
<p>Question:
Based on the above scenario can someone suggest how I can stop the job from running or what else I can try to stop the application from running but keep the cluster running.</p>
<p>Something just accrued to me, if I call <code>sparkContext.stop()</code> that should do it but that requires a bit of work in the code which is OK but can you suggest any other way without code change.</p>

object literal notation vs prototype speed and memory. <p>i came across this post <a href="http://www.webmasterworld.com/javascript/3066162.htm">http://www.webmasterworld.com/javascript/3066162.htm</a>
about how in javascript when you instantiate an object literal if it has methods defined in it then each time one is instantiated its methods are copied as well. so if you have a bunch of instances of the object literal then the copied methods would begin to add up in memory.</p>
<p>how ever he/she states that using prototype to make your methods is more efficient because the methods are not copied for each instance of the constructor object. </p>
<p>is this true? because i was under the impression that prototype allowed you to add properties/methods even after the object was instantiated rather than within the object when its first created.</p>

colorbox around parbox too big. <p>I want to typset some text with colored background <em>and</em> outline, that spans the whole <code>\textwidth</code>. I tried to get this with a <code>colorbox</code> surrounding a <code>parbox</code>. It works in some way, but the <code>colorbox</code> is always a bit bigger than the <code>parbox</code>, causing the colored fill to overlap the outline a bit:
<a href="https://i.stack.imgur.com/AMIgJ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AMIgJ.png" alt="colored fill overlaps outline"></a></p>

</code></pre>
<p>Any ideas are greatly appreciated. Thanks!</p>
<p><strong>Edit:</strong> As supposed in the comments: I already tried removing or changing the <code>\fboxsep</code>-value, but it doesn't change the behavior. Just the space between the text and the border of the boxes tightens, and I want that space...</p>

rPi 3 w/ Rasplex + Multiple USBs Thumb Drives. Hi All,
Recently was thinking about purchasing an rPi3 to use as a media server using Rasplex. I have a couple questions that I think the Reddit community could help me out with:
1.) Can Rasplex read from multiple USBs? Say if I had 2x 64Gb thumbdrives, could both of them have media on them and be found by Rasplex?
2.) If #1 is yes, then would multiple USB drives (lets say 4 for example) drain too much power from the Pi and affect performance?
I would be using the Pi as a server for local networks only. I just find that it would be nice to put it in my pocket and watch movies and play music on long trips.
Thanks! | 0non-cybersec

<p>To up instances with the last version of my app, I copy the user data from the original launch configuration (created with beanstalk) to the launch configuration with spot instances (created by me).</p>
<p>This work fine, but:</p>
<ol>
<li><p>how to update spot instances that have come up from the second autoscaling when the beanstalk update instances managed by him with a new version of the app?</p>
</li>
<li><p>is there another way so easy as, and elegant, to use spot instances and enjoy the benefits of beanstalk?</p>
</li>
</ol>
<p><strong>UPDATE</strong></p>
<p>Elastic Beanstalk add support to spot instance since 2019... see:
