How can I get the relative position of a cell in a range?. <p>I have a range of cells in a workbook, and I want to dynamically replicate them in another workbook. I don't want to use explicit cell references in case the range is moved, I always try to use named ranges for cross-workbook references. So I want to enter a formula in the replicated workbook that uses the named range to get the value that is in the same position. I need to calculate what values to use in the parameters to the OFFSET() function.</p>
<p>What I want is something like this:</p>
<pre><code>=OFFSET('Book1'!NamedRange,x,y)
</code></pre>
<p>What can I put into x and y to calculate the current cell's relative position within a same-sized area in Workbook 2?</p>
<p>Or, is there another way to replicate a named range from one workbook into another?</p>

Let $p$ be a prime number. Prove that in the field $\mathbb Z_p$ the following is true $(x+y)^p= x^p + y^p$. <blockquote>
<p>Let $p$ be a prime number. Prove that in the field $\mathbb Z_p$ the following is true $(x+y)^p= x^p + y^p$</p>
</blockquote>
<p>My idea to do this is to apply the binomial theorem, namely: <br>
$$(x+y)^p = x^p + px^{p-1}y+ {p \choose 2}x^{p-2}y^2+ \dots+ {p \choose {p-2}}x^2y^{p-2}+ pxy^{p-1} + y^p$$
Now, I have made an observation (I do not know if this is true): <br>
$$(\forall n)((n \in \mathbb Z_5 \land n \ne 0 \land n \ne p) \Rightarrow (\exists q\in \mathbb Z_p)({p\choose n}= pq) $$
And so all of these elements corresponding to $n \in \{1,2, \dots, p-2, p-1 \}$ will turn into zeros, and the only remaining elements will be $x^p$ and $y^p$. Is my reasoning good? If so, should I have used induction here?</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:

Silver Screen Shower Scene. Imagine, if you will, you coming out of your bedroom to go to the bathroom in the middle of the night fresh out of rubbing one out. Your hand is still in your underwear, your face is flushed and you're missing a sock. It's darker than the devil's asshole in the hallway so you reach out for the switch with your cleaner hand and flick it on and you see at the end of the hall, staring right back at you, the very living example of all those aliens you saw on the discovery channel. Big fucking huge black eyes in a bigger head and a slender, slate gray body and spindly spider fingers at the end of its skinny arms. Your body stops and your heart goes supersonic as you feel the contents of your bladder empty into the tissue in your hand. It runs from your sight and you scream. Or at least try to. The only sound leaving your mouth is a dry gasp like some retarded fish out of water. And here you are, dick in hand, half-undressed and making your first impression on the one thing you hoped never to meet. That's when the white lights come on from every where with a noise not unlike the sound of God telling you to go fuck yourself and your second attempt at a scream results in your projectile vomiting all over the hallway floor before you faint and it all goes black.

Spark 2.1: Out of Memory when Writing DataFrame to parquet file?. <p>I am trying to write a DataFrame (approx 14 million rows) to a local parquet file, but I keep running out of memory doing so. I have a big map <code>val myMap : Map[String,Seq[Double]]</code> and use this map in a <code>udf</code> for a very large DataFrame via <code>val newDF = df.withColumn("stuff",udfWithMap)</code>. I have 128G of RAM available and after persisting the DataFrame to DISK_ONLY and performing <code>df.show</code>, I still have around 100G of RAM left. However, when I try <code>df.write.parquet</code>, the amount of memory Spark needs skyrockets and I run out of memory. I have also tried broadcasting <code>myMap</code>, but doing so doesn't seem to have any effect on memory. What is the problem?</p>
<p>This is a sample of my code:</p>
<pre><code>scala> type LookupMapSeq = (String, Seq[Double])
scala> val myMap = sc.objectFile[LookupMapSeq]("file:///data/dir/myMap").collectAsMap()
/* myMap.size is about 150,000 and each Seq[String] is of size 200 */
scala> val combineudf = functions.udf[Seq[Double], Seq[String]] { v1 =>
val wordVec = v1.map(y => myMap.getOrElse(y, Seq.fill(200)(0.0)))
wordVec.foldLeft(Seq.fill(200)(0.0)) { case (acc, list) =>
acc.zipWithIndex.map { case (value, i) => value + list(i) }
}
}
scala> import org.apache.spark.storage.StorageLevel
scala> val df6 = df3.withColumn("sum", combineudf(df3("filtered"))).persist(StorageLevel.DISK_ONLY)
scala> df6.show

subprocess gets killed even with nohup. <p>I'm using <code>subprocess.Popen</code> to launch several processes.</p>
<p>The code is something like this:</p>
<pre><code>while flag > 0:
flag = check_flag()
c = MyClass(num_process=10)
c.launch()
</code></pre>
<p><code>MyClass</code> if something like the following:</p>
<pre><code>MyClass(object)
def __init__(self, num_process):
self.num_process = num_process
def launch(self):
if self.check_something() < 10:
for i in range(self.num_process):
self.launch_subprocess()
def launch_subprocess(self):
subprocess.Popen(["nohup",
"python",
"/home/mypythonfile.py"],
stdout=open('/dev/null', 'w'),
stderr=open('logfile.log', 'w'),
shell=False)
</code></pre>
<p>In most of the cases, the launched subprocess dies, sometimes in the middle of the run. In some cases, it completes.</p>
<p>However, if I use <code>subprocess.Popen</code> directly in the while loop, the process continues and finished timely.</p>
<p>Could someone tell me how can I get the processes to run in the background by using subprocess in the way as I described above?</p>

Difficulty understanding Javascript composing in this function. <p>Im following this course and came across this problem</p>
<pre><code>const compose = (f, g) => (a) => f(g(a));
const add1 = (num) => num + 1;
const add5 = (num) => num + 5;
compose(add1, add5)(10)
</code></pre>
<p>As i understand it <code>g(a)</code> gets run first so <code>num = 1</code> makes <code>1</code> for <code>g</code> and <code>10</code> for <code>a</code>, that makes it <code>f(1(10))</code>.
But how does the <code>1</code> and the <code>10</code> know to add, why doesn't it multiply or minus ?</p>

UTF - 8 with JPA and Glassfish 4.0. <p>I am having difficulties with UTF-8 characters. This is a simple JSF project. I use JSF 2.2 and Glassfish 4.0</p>

</code></pre>
<p>When I debug</p>
<pre><code>user.getName()

<p>in this point, I can see the utf-8 characters in my IDE. Also I keep the string in a session - bean and I can see them on the browser fine as well. </p>
<p>Only when they are persisted to DB, they are persisted as: ?????</p>
<p>I can also edit the DB myself and save utf-8 characters. What I mean is, my SQL configuration is good for UTF-8.</p>
<p>The problem is somewhere in JPA. </p>
<p>This is what I have tried: ( all together: )</p>

AITA for sleeping with my best friends ex gf?. So my bestfriend/roomate was dating this girl that he met from our job (we both work at the same UPS hub). He works the evening shift, while I work the graveyard shift and there's this girl I saw that I was really attracted to. I was reluctant to approach her because I am her indirect supervisor ( She wasn't my dedicated employee but I would frequently cover for her supervisor or relay directions to her group for operational purposes)
Fast forward they have been dating for a year or more. One day he ends the relationship and they go their separate ways. He didn't feel the same way about her that she did towards him. I made no effort to talk to her whatsoever.
Fast forward again about a year and a half later he has a new gf that he's really serious about. One day his ex reaches out to me to buy some weed from me (I was growing at the time and would post pictures om my snapchat). I met up with her to sell her some bud and she asked me to hangout for a little bit and I agreed. I had absolutely no intention of hooking up with her, because of her history with my roommate, but one thing led to another and we ended up sleeping together. It happened several more times after this mainly because I felt very comfortable around her and enjoyed her company.
One day I decided to tell him what was going on, because I don't like to keep secrets from my close friends. Initially he just brushed it off, but the next day he told me he felt like I betrayed him and it was fucked up that I had hooked up with her on several different occasions.
For me I feel like I did nothing wrong because i didn't initiate or seek her out, but also because he was the one who broke up with her and on top of that it has been well over a year AND he has a new gf who he is in love with. He said he still has strong feelings for her and if that's true than why did you end the relationship? He told me to promise him that I would never see her again and I agreed.
Am I wrong for wanting to be around someone that makes me feel like I am cared about eventhough they have history with a very close friend of mine? I didn't want to get inimate with her, she initiated it and I didn't stop her because it felt right and I was very lonely. Is it more important that I keep him happy or pursue my own happiness?
TLDR; my roommate broke up with his gf a year and a half ago and currently has a new gf. His ex contacted me and we ended up getting intimate with eachother unintentionally (at least on my behalf I can't speak for her intentions). I felt the need to confess this to him and he feels like I betrayed our friendship and wants me to promise never to talk to her again. He feels like he can't trust me anymore.

Creating several precompiled header files using GNU make. <p>I use gcc (running as <code>g++</code>) and GNU make.
I use gcc to precompile a header file <code>precompiled.h</code>, creating <code>precompiled.h.gch</code>; the following line in a Makefile does it:</p>
<pre><code># MYCCFLAGS is a list of command-line parameters, e.g. -g -O2 -DNDEBUG
precompiled.h.gch: precompiled.h
g++ $(MYCCFLAGS) -c $< -o $@
</code></pre>
<p>All was well until i had to run <code>g++</code> with different command-line parameters.
In this case, even though <code>precompiled.h.gch</code> exists, it cannot be used, and the compilation will be much slower.
In the gcc documentation i have read that to handle this situation,
i have to make a directory called <code>precompiled.h.gch</code> and put
the precompiled header files there,
one file for each set of <code>g++</code> command-line parameters.</p>
<p>So now i wonder how i should change my Makefile to tell <code>g++</code> to create
the gch-files this way.
Maybe i can run <code>g++</code> just to test whether it can use any existing file
in the <code>precompiled.h.gch</code> directory,
and if not, generate a new precompiled header with a unique file name.</p>
<p>Does gcc have support for doing such a test?</p>
<p>Maybe i can implement what i want in another way?</p>

Why can't I use a list as a dict key in python?. <p>I'm a bit confused about what can/can't be used as a key for a python dict. </p>
<pre><code>dicked = {}
dicked[None] = 'foo' # None ok
dicked[(1,3)] = 'baz' # tuple ok
import sys
dicked[sys] = 'bar' # wow, even a module is ok !
dicked[(1,[3])] = 'qux' # oops, not allowed
</code></pre>
<p>So a tuple is an immutable type but if I hide a list inside of it, then it can't be a key.. couldn't I just as easily hide a list inside a module?</p>
<p>I had some vague idea that that the key has to be "hashable" but I'm just going to admit my own ignorance about the technical details; I don't know what's really going on here. What would go wrong if you tried to use lists as keys, with the hash as, say, their memory location?</p>

Python: Summing x elements in a list. <p>i wasn't able to find the answer using the search function so i am starting this thread.</p>
<p>Consider having a list that is divideable by x.
For example:</p>
<pre><code>onetonine = [1,2,3,4,5,6,7,8,9]
</code></pre>
<p>The example x would be 3 in this case.</p>
<p>Now i want to create a new list with </p>
<pre><code>len(onetonine)/x
</code></pre>
<p>elements, which would mean 3 elements.</p>
<p>The important part is, that i want the elements of the new list to be the sum of every x elements of the old list.
This means:</p>
<pre><code>newlist = [6, 15, 24]
</code></pre>
<p>So basically take x=3 elements of my old list and add them. Repeat until done.</p>
<p>I wasn't able to get a working solution for this so i am asking for help.</p>

How small must $x$ be to have $\frac{1}{2} \cdot 10^{-8}$ accuracy?. <blockquote>
<p>For small values of $x$, how good is the approximation $cos(x)\approx 1$? How small must $x$ be to have $\frac{1}{2} \cdot 10^{-8}$ accuracy?</p>
</blockquote>
<p>My teacher told me, it would be easier to do the second part of the question first, so I need to find out how small $x$ be to have $\frac{1}{2} \cdot 10^{-8}$ accuracy</p>
<p>So as far as I understand, I need to solve for $x$ in the following equation </p>
<p>$|cos(x)-1|<\frac{1}{2} \cdot 10^{-8} \Rightarrow \\
|x| < \ arccos(1-\frac{1}{2} \cdot 10^{-8}) \Rightarrow \\
x \in \ (-arccos(1-\frac{1}{2} \cdot 10^{-8}),arccos(1-\frac{1}{2} \cdot 10^{-8}))$</p>
<p>but that just seems like a messy answer. Any ideas?</p>

Holder Continuous Functions on $[0,1]$ are complete + Banach space. <p>I am studying for an Analysis prelim and I am stuck on how to show that the following space of Holder continuous functions is complete:</p>
<p>$$\Lambda_{\alpha}([0,1]) = \{f: [0,1] \rightarrow \mathbb{R} \mid \sup_{x,y \in [0,1], x\neq y} \frac{|f(x) - f(y)|}{|x-y|^{\alpha}} < \infty \text{ and } 0< \alpha \leq 1\}$$
with the norm $\| \cdot \|_{\Lambda_{\alpha}}$ defined by
$$\|f\|_{\Lambda_{\alpha}} = |f(0)| + \sup_{x,y \in [0,1], x\neq y} \frac{|f(x) - f(y)|}{|x-y|^{\alpha}}$$
I think its easy to see that $\Lambda_{\alpha}([0,1]) \subset B([0,1])$, i.e., it is a subset of bounded functions on $[0,1]$ which is complete. My thought is that if I let $\{f_n\}$ be a Cauchy sequence in $\Lambda_{\alpha}([0,1])$ and let $f \in B([0,1])$, such that $f_n \rightarrow f$ in the uniform norm, then we can show $f \in \Lambda_{\alpha}([0,1])$ and that $f_n \rightarrow f$ in the Holder norm defined above. Not sure how to show this though. Perhaps I could also somehow show that any absolutely convergent series converges in $\Lambda_\alpha$, but I'm not sure how to do this either. Any help would be appreciated.</p>

Lagrange's identity in the complex form. <p>I am trying to show Lagrange's identity in the complex form; that is,
$$
\Bigl\lvert\sum_{i = 1}^na_ib_i\Bigr\rvert^2 = \sum_{i = 1}^n\lvert a_i\rvert^2\sum_{i = 1}^n\lvert b_i\rvert^2 - \sum_{1\leq i\lt j\leq n}
\lvert a_i\bar{b}_j - a_j\bar{b}_i\rvert^2
$$
Then
\begin{align}
\Bigl\lvert\sum_{i = 1}^na_ib_i\Bigr\rvert^2 &=
\Bigl(\sum_{i = 1}^na_ib_i\Bigr)\Bigl(\sum_{j = 1}^n\bar{a}_j\bar{b}_j\Bigr)\\
&= \sum_{i,j=1}^na_i\bar{a}_jb_i\bar{b}_j\\
&= \begin{aligned}
a_1\bar{a}_1b_1\bar{b}_1 &+ \cdots + a_n\bar{a}_1b_n\bar{b}_1+\\
\vdots\phantom{....} & \phantom{...}\ddots\phantom{......}\vdots\phantom{.....}+\\
a_1\bar{a}_nb_1\bar{b}_n &+ \cdots + a_n\bar{a}_nb_n\bar{b}_n
\end{aligned}
\end{align}
I see that down the diagonals I will have $\sum_{i=1}^n\lvert a_i\rvert^2\sum_{i=1}^n\lvert b_i\rvert^2$ which leaves me with
$$
\sum_{1\leq i\leq j\leq n}a_i\bar{a}_jb_i\bar{b}_j+a_j\bar{a}_ib_j\bar{b}_i\tag{1}
$$
but I don't see how equation $(1)$ is equal to
$$
\lvert a_i\bar{b}_j - a_j\bar{b}_i\rvert^2 = \lvert a_i\rvert^2\lvert b_j\rvert^2 + \lvert a_j\rvert^2\lvert b_i\rvert^2 - a_i\bar{a}_jb_i\bar{b}_j - a_j\bar{a}_ib_j\bar{b}_i.
$$</p>

From my experience.... it seems like if someone you haven't met uses the word pot or marijuana, they probably don't smoke. If they say weed or bud, then they usually do.
Has anyone else noticed this? It's a good way to tell without having someone freak out if they do not condone its use. | 0non-cybersec

Simple method of detecting and reporting server outage?. <p>I'm looking for a super simple way to monitor one server from another, in case the other goes down (e.g. based on ping), and then send an email if it does. Is there anything out there like this installable via the standard package manager (debian)? I'm aware of things like nagios and monit, but these are much more complex than I need.</p>
<p>(The servers are on a private network, so I can't use third party web services)</p>

How To Make Ubuntu 13.04 Work With DisplayLink Monitor?. <p>I recently purchased an <a href="http://rads.stackoverflow.com/amzn/click/B0073BOCNU">AOC E2251FWU DisplayLink</a> monitor. When I plug this into my <a href="https://www.system76.com/laptops/model/gazp9">System76 Gazelle Professional</a> running Ubuntu 13.04 Raring Ringtail, nothing happens. Under 'displays', no additional display is detected. On Mac and Windows, this monitor is plug-and-play after installing DisplayLink's drivers.</p>
<p>Having read that previous versions of Ubuntu had plug and play support for DisplayLink monitors, I'm surprised that Ubuntu 13.04 does not! The 'xserver-xorg-displaylink' driver is not available in the 13.04 repositories. I read that it has become baked into the Linux kernel.</p>
<p>Does anybody know how to get a DisplayLink device to actually work on Ubuntu 13.04? I'm looking to get a simple extended display. I've done my due dilligence and Googled around, but no solution I can find works for me.</p>

Confused about Linux "route add" commands for this diagram. <p>I am confused about this <a href="https://www.cs.umb.edu/~gghinita/it443/network-diagram.pdf" rel="nofollow noreferrer">network diagram</a>. </p>
<p>In class the router R1 was assigned to me and other students were given various routers/workstations on the diagram. Our task was to set the network up with ifconfig and route commands. Since the main router only really had one physical interface, we used an alias as well (eth0 and eth0:1).</p>
<p>I used the following commands to set up R1 (initially I had the gateways wrong) but my professor corrected me:</p>
<pre><code># set interfaces (1 physical/1 virtual)
ifconfig eth0 10.0.0.4/24
ifconfig eth0:1 10.0.14.252/24
# Add routes for remaining 4 LANs:
route add -net 10.0.12.0 netmask 255.255.255.0 gw 10.0.14.27
route add -net 10.0.17.0 netmask 255.255.255.0 gw 10.0.14.34
route add -net 10.0.7.0 netmask 255.255.255.0 gw 10.0.14.27
route add -net 10.0.28.0 netmask 255.255.255.0 gw 10.0.14.34
# once everyone can ping eachother successfully
# connect the entire 10.0.0.0/24 network to the
# outside 192.168.104.0/22 network
route add default gw 10.0.0.1
# set up forwarding to outside gateway
sysctl -w net.ipv4.ip_forward=1
</code></pre>
<p>I am most confused about why the gw's for the route commands are 10.0.14.34 and 10.0.14.27.</p>
<p>What would the route commands and gateways be for R3 or R5? Or R2 and R4? I can see that a router's two adjacent networks get added with the two ifconfig commands; there is no need to set their routes. But I am really getting confused on what each side of each router is using for a gateway. </p>
<p>Any help is very much appreciated! Thank you. </p>

Hilbert-Schmidt operator defined by non-orthogonal basis. <p>I have the following operator on $L^2(0,1)$</p>
<p>$$ Tf = \sum_{n \geq 0} 2^{-n}\langle f,v_n\rangle v_n$$</p>
<p>Where $v_n(t) = t^n$.</p>
<p>I was able to prove that it is Hilbert-Schmidt, but now I need to calculate its Hilbert-Schmidt norm, and its integral kernel. The problem is that it is defined through an indipendent system of vectors (the polynomials) which are dense but not orthogonal (if it had been $v_n(t) = \exp(2\pi i nt)$ it would have been much easier. How do I identify the eigenvectors?</p>
<p>I was thinking about setting $t = \exp(2\pi i x)$ and reduce to the orthogonal case somehow but I reach incorrect results, I am not sure of where I am doing wrong.</p>
<p>Can anybody help me?</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:

Same program, same JVM, but vastly different memory requirements and execution time on different machines - why?. <p>I'm trying to run a <a href="http://ccl.northwestern.edu/netlogo/" rel="nofollow noreferrer">NetLogo</a> (a java simulation framework) simulation on a cluster as part of a large experiment. I was surprised at the seemingly massive memory requirement of a (relatively) simple simulation. On the cluster it throws "java.lang.OutOfMemoryError: Java heap space" exceptions for anything less than "-Xmx2500M" heapsizes. A single execution takes 5 hours to run. I ran the same experiment on both my Macs (iMac and MacBook Pro), and they executed in less than one hour, with "-Xmx1024" giving no errors. The cluster jobs require "-XX:MaxPermSize=250M" whereas on my Macs no increase above default is required. I ran the same code, the same inputs, using the exact same jars in all cases. </p>
<p>64 bit JVMs are used in each case (and as far as I know these are pretty similar):</p>
<pre><code><on the cluster>
$ java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
<on my macs>
$ java -version
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04-415-10M3646)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01-415, mixed mode)
</code></pre>
<p>And I am running Client JVM in all cases (was initially using Server on cluster, switching to client made no difference). I have tried executing on the cluster with java 7, same huge memory and execution time issues. </p>
<p>I am completely perplexed, no one I have spoken to can explain this. Has anyone out there come across this before? Any help greatly appreciated!</p>

Dual booting: 0xc000000e Windows Error when installing GRUB. <p><strong>Hi everyone!</strong><br>
This is my first question so correct me please if I´m asking something wrong. </p>
<p>So my Problem is:<br>
I´ve got a Lenovo E31-70 with pre-installed Windows 10 home 64bit and I tried to dual-boot Kali Linux on it.<br>
First I´ve created an Partition with 100GB. Than I installed Kali Linux and the GRUB loader from an .iso image from an USB. The Installation was working fine and finally I had all installed.Then I tried to boot Windows and I got a boot error, but Linux was working well.<br>
For some reason i cannot upload an photo of the error, but: </p>
<pre><code>File: \Boot\BCD
Status: 0xc000000e
Info: The Boot Configurations Data for your PC is missing or contains errors.
</code></pre>
<p>After a bit searching I found that: <a href="http://answers.microsoft.com/en-us/windows/forum/all/0xc000000e-boot-error/ef08ab00-e130-4301-bc80-79d5b414a81f?auth=1" rel="nofollow noreferrer">http://answers.microsoft.com/en-us/windows/forum/all/0xc000000e-boot-error/ef08ab00-e130-4301-bc80-79d5b414a81f?auth=1</a><br>
<strong>THE SECOND ANSWER</strong></p>
<p>So I downloaden an Windows 10 .iso on my USB, started Windows repair, and wrote<br>
<code>bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd</code></p>
<p>All worked fine, Windows was completly restored,
but when I restarted the PC, GRUB doesn´t appear!
I´ve tried restarting the Notebook several times, with the same result.</p>
<p>Than I found this solution: <a href="https://forums.kali.org/showthread.php?20559-How-To-Repair-Kali-Linux-Grub-With-Kali-Linux-Live-Cd-Dual-Boot-With-Windows-7" rel="nofollow noreferrer">https://forums.kali.org/showthread.php?20559-How-To-Repair-Kali-Linux-Grub-With-Kali-Linux-Live-Cd-Dual-Boot-With-Windows-7</a></p>
<p>Again all worked fine. When I rebooted the Notebook, GRUB appeared. I thought it was the end... It wasn´t.<br>
Because when I´ve tried to start Windows, I got the same 0xc000000e Error again. </p>
<p><strong>NOTE:</strong><br>
Fast boot is turned off<br>
Boot Mode is legacy(can switch to UEFI) </p>
<p><strong>Conclusion:</strong>
When repairing Windows, GRUB doesn´t appear.
When repairing GRUB, Windows boot error.</p>
<p>I guess that GRUB is overriding Windows boot data...</p>
<p><strong>[EDIT]</strong><br>
I can boot windows if i switch to UEFI. The problem is: I don´t want to switch in BIOS from UEFI to Legacy every time i need to boot another OS. Is there any way to boot Windows 10 in legacy or start GRUB in UEFI?</p>

Security controls around data in motion?. <p>I am an Information Security Analyst, trying to understand the difference between data in transit and data in motion. I found the listed below definitions:</p>
<p>Data In Transit is defined as data moving outside of the server such as between client and server, server to server, web app server to DB server and vice/versa.</p>
<p>Data In Motion is defined as being in preparation of transmission, moving around or place to place on or within the server itself but not transiting off of the server, or sometimes between servers when the connection between servers is a direct private connection such as data moving from server to SAN/NAS, not over a traditional LAN.</p>
<p>Reference - <a href="http://commonsensesecurity.net/difference-data-transit-data-motion" rel="nofollow noreferrer">http://commonsensesecurity.net/difference-data-transit-data-motion</a></p>
<p>What security controls need to be in place to protect data in motion which are different than data in transit?</p>

Ubuntu Server: Apache2 seems to attach .php to URI. <p>I'm using the php library tonic for web services. My resource is as example at </p>
<pre><code>base-uri/myResource
</code></pre>
<p>Now if a file myResource.php exists in that directory, the url mod_rewrite gets to see is</p>
<pre><code>base-uri/myResource.php
</code></pre>
<p>which then fails the rewrite conditions and my application breaks (app works on apache on windows)</p>
<p>If I rename myResource.php to my myResourceClass.php (or anything else), it works.</p>
<p>So it seem that apache or one if its modules assumes that with base-uri/myResource I want to call base-uri/myResource.php but only if myResource.php exists.</p>
<p>Is this a general issue or can I somewhere configure this to not happen?</p>
<p>thanks!</p>
<p>EDIT:</p>
<p>see</p>
<p><a href="https://serverfault.com/questions/359290/how-to-set-up-a-basic-mod-rewrite">How to set up a basic mod_rewrite?</a></p>
<p>The answer contains the same observation!</p>
<p>ANSWER:</p>
<p>The issue is the default Apache configuration on Ubuntu:</p>
<pre><code>Options Indexes FollowSymLinks MultiViews
</code></pre>
<p>MultiViews is changing request_uri from myResource to myResource.php.</p>
<p>Solutions:</p>
<ul>
<li>disable MultiViews in .htaccess: Options -MultiViews</li>
<li>remove MultiViews from default config</li>
<li>rename the file as example to myResourceClass</li>
</ul>
<p>I chose last option because that should work regardless of configuration and I only have 3 such files so the change took about 30 secs...</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>

What is the purpose of ValidationContext when implementing IValidatableObject. <p>I have implemented <code>IValidatableObject</code> several times and have never found out what the purpose of parsing <code>ValidationContext</code> to the Validate method is - my typical <code>IValidatableObject</code> implementation looks something like this:</p>
<pre><code> public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
{
if (Prop1 == Prop2)
{
yield return new ValidationResult(
"Prop1 and Prop2 must be different.",
new[] {"Prop1", "Prop2"});
}
}
</code></pre>
<p>Is there anything that I have missed that I could have used <code>validationContext</code> for?</p>
<p>EDIT: I'm using ASP.NET MVC and this is implemented in the class - not in the controller.</p>

<p>I was reading the introduction to Unity and it says the launcher was made into a sidebar for convenience on widescreen monitors. Is it configurable, say to move it along the bottom of the screen, for people like me who use a "widescreen" monitor in "Portrait" mode?</p>
<p>If not, this is a dealbreaker for me, I'm afraid.</p>

Can't install usermin or virtualmin: "Expecting form-data encoding, but got normal encoding". <p>This is a fresh server, with webmin freshly installed-- in fact, installing usermin is the first action I'm (trying to) take with it. I'm logged in with a user that has sudo privileges, however I've also tried it as root.</p>
<p>I select Usermin from the list of unused modules, then "Install Usermin tar.gz package". This brings me to an error screen that says "<strong>Expecting form-data encoding, but got normal encoding</strong>".</p>
<p>The lack of help I've been able to find for this is disheartening. Either no one uses Usermin, or no one has ever had this error. In fact, "usermin" isn't even an existing tag here.</p>
<hr>
<p>Trying to install virtualmin gives a different error: <strong>Failed to install module from <a href="http://download.webmin.com/download/virtualmin/webmin-virtual-server_5.04.gpl_all.deb" rel="nofollow">http://download.webmin.com/download/virtualmin/webmin-virtual-server_5.04.gpl_all.deb</a> : Not a valid module file : tar: This does not look like a tar archive tar: Skipping to next header tar: Exiting with failure status due to previous errors</strong>. </p>
<p>To arrive at that I followed the <a href="http://www.webmin.com/vdownload.html" rel="nofollow">install instructions</a>: Go to Webmin Configuration-> Webmin Modules-> Install from ftp or http URL.</p>
<hr>
<p>Neither usermin or virtualmin are critical for me. I've never used them before, but I'm setting up a new server today, and thought a graphical UI might make my life a little easier. Webmin itself installed just fine.</p>

Metric ($f$-divergence) on space of probability measures that satisfies pythagorean theorem. <p>Let <span class="math-container">$E$</span> be a polish space, <span class="math-container">$\mathcal{P}(E)$</span> the Borel probability measures on <span class="math-container">$E$</span> with the topology of weak convergence and <span class="math-container">$\mathcal{Q} \subset \mathcal{P}(E)$</span> a convex and compact set.</p>
<p>First, the motivation for my question:</p>
<p>The Kullback Leibler divergence (or relative entropy) <span class="math-container">$R : \mathcal{P}(E)\times \mathcal{P}(E) \rightarrow [0, \infty]$</span> is defined by <span class="math-container">$R(\nu, \mu) = \int \frac{d\nu}{d\mu} \log(\frac{d\nu}{d\mu}) d\mu$</span> if <span class="math-container">$\nu$</span> is absolutely continuous with respect to <span class="math-container">$\mu$</span> and <span class="math-container">$R(\nu, \mu) = \infty$</span>, else.</p>
<p>Let <span class="math-container">$\theta \in \mathcal{P}(E)$</span> and <span class="math-container">$\theta^{\ast}_R := \arg\min_{\mu \in \mathcal{Q}} R(\mu, \theta)$</span> be the information projection of <span class="math-container">$\theta$</span> onto <span class="math-container">$\mathcal{Q}$</span>. As a consequence of the pythagorean like theorem for relative entropy (c.f. <a href="https://www.jstor.org/stable/2959270?seq=1#metadata_info_tab_contents" rel="nofollow noreferrer">Csiszár (1975)</a>, Theorem 2.2) it holds
<span class="math-container">\begin{equation}
\label{eq1}
\forall \mu \in \mathcal{Q} : R(\theta^{\ast}_R, \theta) + R(\mu, \theta^{\ast}_R) \leq R(\mu, \theta)
\end{equation}</span></p>
<p>My question is whether there exists a <strong>metric</strong> <span class="math-container">$d$</span> on <span class="math-container">$\mathcal{P}(E)$</span> which satisfies the same kind of result.
So if <span class="math-container">$\theta^{\ast}_d := \arg\min_{\mu\in\mathcal{Q}} d(\mu, \theta)$</span>, it should hold
<span class="math-container">$$
\forall \mu \in \mathcal{Q}: d(\theta^{\ast}_d, \theta)^2 + d(\mu, \theta^{\ast}_d)^2 \leq d(\mu, \theta)^2
$$</span></p>
<p>Ideally, the metric <span class="math-container">$d$</span> should metrize weak convergence, but I am thankful for any approaches or pointers.</p>

Randomized Polynomial Hierarchy?. <p>I wonder, what would happen, if in the definition of $PH$ (Polynomial Hierarchy, see, e.g., <a href="https://en.wikipedia.org/wiki/Polynomial_hierarchy">here</a>), the role of $NP$ would be replaced by $RP$? </p>
<p>It seems, we could still build a hierarchy, the same way as $PH$ is built, just using $RP$ everywhere instead of $NP$, and $coRP$ instead of $coNP$. Let us call it Randomized Polynomial Hierarchy ($RPH$). </p>
<p>My first guess is that $RPH\subseteq BPP$, or maybe $RPH=BPP$. It is based on the known fact that $NP=RP$ implies $PH=BPP$. Nevertheless, if $P\neq RP$, then $RPH$ could still be a proper, infinite hierarchy within $BPP$. </p>
<p>Of course, the edge of the issue is blunted by the fact that $P=RP$ is conjectured (even $P=BPP$), which would flatten $RPH$ into $P$. However, $P=RP$ is not known at this time, and it has resisted all proof attempts so far. Therefore, $RPH$ still has at least some chance to be a proper hierarchy.</p>
<p>While $RPH$, admittedly, has a good chance to be "flat," could the concept still be useful for something nontrivial? Here is an example: if one can prove $RPH=BPP$, then it would yield that $P=RP$ implies $P=BPP$, which, I think, would be an interesting result.</p>
<p>Is anything known about this?</p>

CLT for Martingales. <p>I posted this question originally in math stack exchange, but I got no answer.
(<a href="https://math.stackexchange.com/questions/2604591/clt-for-martingales">https://math.stackexchange.com/questions/2604591/clt-for-martingales</a>)</p>
<p>In wikipedia, there is a version of a CLT for Martingales, which I cannot find any reference to. ( <a href="https://en.wikipedia.org/wiki/Martingale_central_limit_theorem" rel="nofollow noreferrer">https://en.wikipedia.org/wiki/Martingale_central_limit_theorem</a>)</p>
<p>The theorem claims the following:</p>
<blockquote>
<p>Let $X_1,X_2,...$ be a martingale with bounded increments, i.e.
$ \mathbb{E} [ X_{t+1}-X_t | X_1,...,X_t]=0$ and $|X_{t+1}-X_t|\le k$ almost surely for some $k$ and all $t$.</p>
<p>Define $\sigma_{t}^2=\mathbb{E}[(X_{t+1}-X_t)^2|X_1,...,X_t]$, and let $\tau_\nu=\min\left\{t\ :\ \sum_{i=1}^{t} \sigma_i^2 \ge \nu\right\}$.</p>
<p>Then $\frac{X_{\tau_{\nu}}}{\sqrt{\nu}}$ converges to $N(0,1)$ in distribution as $\nu \longrightarrow \infty$.</p>
</blockquote>
<p>I would like to know how to prove this or if there is any reference on the web.</p>

Does @media with no arguments do anything?. <p>I've inherited some code from a ... questionable ... web developer. There are hundreds of style sheets referenced from each page of the site and each of them is riddled with extra @media tags that appear to be malformed. They are just:</p>

/* A bunch of CSS rules */
}
@media {
/* A bunch more CSS rules */
}
</code></pre>
<p>I'm trying to simplify the code base so that it will be easier for me to maintain. My question is: Is there any possible purpose at all in having @media by itself like that with no media type or media function arguments?</p>
