Connecting ice maker to a PVC water line. I will soon be taking delivery of a fridge with ice maker. This is the first fridge I've had which has an ice maker in it, so I need to run a water line to the fridge. I could find a copper line to tie into but most of what's near the fridge is PVC. Tying into a copper line looks dead simple with one of those vampire tap things, but I've not seen anything out there about tying into a PVC line.
Is there an easy, lazy-man way to tie into a PVC water line? Or is my only alternative to cut the PVC and install some sort of tee?

solution set for congruence $x^2 \equiv 1 \mod m$. <p>if $m$ is an integer greater than 2, and a primitive root modulo $m$ exists, prove that the only incongruent solutions of $x^2 \equiv 1 \mod m$ are $x \equiv \pm 1 \mod m$.</p>
<p>I know that if a primitive root mod $m$ exists, then $m = 1, 2, 4, p^m,$ or $2p^m$, where p is an odd prime and $m$ is a positive integer. Obviously I can check the cases where $m = 1, 2, 4$ by hand but I am having trouble proving the other two cases.</p>

Add event handler for body.onload by javascript within <body> part. <p>We want to include a maps from Google Maps API in our document. The documentation tells to initialize the map with a function called by the onload() event of the body.</p>
<p>The ordinary way to call:</p>
<pre><code><body onload="initialize_map();">
</code></pre>
<p>This doesn't work out for us because we're using Template::Toolkit and the <code><body></code> tag is already included in our wrapper. In short: The <code><body></code> tag is already printed when our javascript code starts running.</p>
<p>I tried something like this but it does only work for <code>onclick</code>, not <code>onload</code>. I guess that's because the javascript code is beneath the <code><body></code> tag itself.</p>
<pre><code>var body = document.getElementsByTagName("body")[0];
body.addEventListener("load", init(), false);
function init() {
alert("it works!");
};
</code></pre>
<p>Any help how to fire up a Google Maps map appreciated!</p>

Burrows-Wheeler transform backward search: how to find suffix index?. <p>BWT backward search algorithm is pretty straightforward if we only need the multiplicity of a pattern. However I also need to find the suffix indices (i.e. positions in the reference string where a pattern occurs). e.g., given string <em>banana</em> and pattern <em>an</em>, it occurs twice at positions 1 and 3. </p>
<p>I could compute all suffixes and sort them, but that would increase the time complexity to O(nlogn), n being length of the reference string. Is there a way to do this and still keep the O(length of pattern) time complexity?</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>

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>

Why doesn't multiplying two matrices with NumPy work sometimes?. <p>Using NumPy and attempting to multiply matrices together sometimes doesn't work. For example</p>
<pre><code>import numpy as np
x = np.matrix('1, 2; 3, 8; 2, 9')
y = np.matrix('5, 4; 8, 2')
print(np.multiply(x, y))
</code></pre>
<p>can return </p>
<pre><code>Traceback (most recent call last):
File "vector-practice.py", line 6, in <module>
print(np.multiply(x, y))
ValueError: operands could not be broadcast together with shapes (3,2) (2,2)
</code></pre>
<p>I understand that I can't multiply these shapes, but why not? I can multiply these two matrices on paper, so why not in NumPy? Am I missing something obvious here?</p>

Complexity for the function maxheight in a binary tree. <p>The function: </p>
<pre><code>MAX-HEIGHT(node)
if(node == NIL)
return -1;
else
return max(MAX-HEIGHT(node.leftChild), MAX-HEIGHT(node.rightChild)) + 1;
</code></pre>
<p>Suppose that we have N nodes and we call the function with <code>MAX-HEIGHT(root).</code></p>
<p>I think that the complexity of this function is O(N) because we need to visit each node.
However, I am not sure and I can not prove it rigorously. Please give me a good explanation why it is O(N), if it is O(N), and why not if it is not O(N).</p>
<p>So, what is the complexity? </p>

Request header field Access-Control-Allow-Headers is not allowed by itself in preflight response. <p>I have come across CORS issues multiple times and can usually fix it but I want to really understand by seeing this from a MEAN stack paradigm. </p>

<p>Request header field Access-Control-Allow-Headers is not allowed by Access-Control-Allow-Headers in preflight response</p>

<p>I assumed that I could do this:</p>
<pre class="lang-js prettyprint-override"><code>app.use(function(req, res, next) {
res.header("Access-Control-Allow-Headers","*")
})
</code></pre>
<p>or the equivalent but this doesn't seem to fix it. I also of course tried</p>

$R$ a DVR with fraction field $K.$ What are the $R$-submodules of $K^n?$. <p>It is known that if $R$ is a DVR with fraction field $K,$ then the $R$-submodules of $K$ are $0,K,x^nR,$ with $n$ any integer and $x$ a generator of the maximal ideal of $R.$ I was wondering if there is a simple structure theorem for the $R$-submodules of $K^n,$ the $n$-dimensional vector space over $K$ (similar to that for finitely generated torsion-free modules over a Dedekind domain). I know that the subroups of $\mathbb{Q}$ are somewhat complicated to describe, but was wondering, in particular, if the situation gets any nicer with, say, $\mathbb{Z}_P$-submodules of $\mathbb{Q}^n,$ where $P$ is a nonzero prime ideal of $\mathbb{Z}.$</p>

Nonlinear Nuclear Operators ?. <p>Is there a "right" definition of the nuclear
operator in the nonlinear framework ? Of course, such an operator
must be compact, while a linear operator should be "nonlinearly"
nuclear iff it is nuclear as usual. [These are naive conditions, of course.]
Since here the Frechet derivative is useless. For example, the "cubing"
self-map of $\ell^{2}$, i.e., $(x_{n})$ $\rightarrow\(x_{n}^{3})$
, has nuclear derivative at each point, yet it is clearly noncompact.
OTOH, it seems that a [nonlinear] Lipschitz $p$-summing operator
need not to be power compact. Some thoughts ?</p>

Roger. I own 250,000 acres. I have 10,000 head of cattle and they call my place The Jolly Roger."
The second Texan says, "My name is John. I own 350,000 acres. I have 50,000 head of cattle and they call my place Big John's."
They both look down at the old man who says, "My name is Irving and I own only 300 acres."
Roger looks down at him and say, "300
Acres? What do you raise?"
“Nothing" Irving says.

How to ensure my CustomPaint widget painting is stored in the raster cache?. <p>I have an app that displays a black dot at the point where the user touches the screen like this:</p>
<p><a href="https://i.stack.imgur.com/YpTDS.png" rel="noreferrer"><img src="https://i.stack.imgur.com/YpTDS.png" alt="enter image description here"></a></p>
<p>The black dot can be moved by the user as he/she drags his finger on the screen.</p>
<p>The background is an expensive paint operation, so I have created two separate widgets in a stack, hoping that the background widget painting will be stored in the Flutter raster cache. But it's not stored - Flutter calls my expensive paint method every time the black dot moves.</p>

}
}

directory sorting text. <p>I am running Ubuntu 12 and a while back I wrote a small script file to manipulate a text file which I use for a workshop index.</p>
<p>The most important function is to sort the file into alphabetical order that I did with the command<br>
<code>sort -df</code><br>
This worked well when first written as the directory sort paid attention to leading spaces and tabs placing lines of text with leading spaces at the head of the file. </p>
<p>It now will not do that and the same script file just does a straight alphabetical sort and ignores spaces. This is not what I need. Reading the manual (man) and other documentation seems to agree with me. </p>
<p>What can I do to return to what I need? Thanks for any help you can supply.

OpenVPN needs a gateway parameter fo a --route option. <p>I've got an OpenVPN client that isn't connecting to the vpn server. I've pasted the full log below, but in particular, I'm getting these issues with the route:</p>
<blockquote>
<p>OpenVPN ROUTE: OpenVPN needs a gateway parameter for a --route option and no default was specified by either --route-gateway or --ifconfig options</p>
<p>OpenVPN ROUTE: failed to parse/resolve route for host/network: 10.8.0.1</p>
</blockquote>
<p>There are many clients with the same client config that are connecting just fine. This client (and a few others) was connected, lost its connection due to the system time becoming too far out of sync (I believe), has since synced the system time, but is now still unable to connect. Usually, restarting the system fixes the issue. So it doesn't appear to be an issue with the VPN configuration but something with the client system.</p>
<p>I don't really know enough to understand the route issues or fix them. I do need to deal with recovering from the time sync issue, but for now, why can't I manually start a VPN connection from this client? What would cause OpenVPN to now need a gateway parameter?</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:

<p>Now, I understand that this has to do with code signing (right?), but how do I go about updating or verifying the correct code signature?</p>
<p>I see that other people have had a similar issue by having a non-alpha/non-numeric symbol in their Product Name, however, my Product name is AppNameWatch, and AppNameWatch Extension. Apple generates the Extension file with the space character in-between AppNameWatch and Extension, so I assume that that is fine and not the cause of the problem. </p>
<p>I have also tried cleaning/re-building/cleaning the build folder and deleting derived data.</p>
<p>Any help would be greatly appreciated, thank you. </p>
<p><strong>EDIT/UPDATE:</strong></p>
<p>Looks like this is an issue related to cocoapods. After moving all my frameworks to be managed by Carthage, the app is installing and running as it should with no errors related to modified resources. </p>

Sql server 2008 filestream maximum number of rows. <p>We are using <strong>filestreams</strong> in <strong>Microsoft SQL Server 2008 (SP2) - 10.0.4000.0 (X64) and Windows server 2008</strong> to store millions of files. Since there are millions of files all of them are grouped into 100 filegroups and inserted sequntially one after another filegroup. Now we have around 15K files in each filegroup and expected to grow to 20K soon. so we want to know is there any maximum limit of rows that a filegroup can have to give optimum performance or is there any maximum on the operating system side for optimum performace as we are storing or going to store around <20K files in single folder?</p>
<p>Any suggestion to the right resources will also be very helpful.</p>
<p>I have a link to msdn blog which states that</p>
<blockquote>
<p>4.Check if FILESTREAM directory containers do not have more than 300,000 files individually, as NTFS performance degradation may be an
issue especially when generation of 8.3 filenames is enabled.</p>

What are the risks of in-person private currency exchanging for travellers?. <p><a href="https://bitcoin.stackexchange.com/a/3885/516">This answer</a> suggests popularity growth of people privately exchanging bitcoins for a physical currency, in person. This might occur in "coffee shops, hotels, hostels, hackerspaces, etc".</p>
<p>An example would be 2 travellers meeting in a hostel in, say, the UK. Traveller A has just been to the USA and traveller B is about to go there. Traveller A has US$200 that's no longer needed, so he agrees to exchange it for some of traveller B's bitcoins.</p>
<p>Definitely assume traveller B has a mobile phone or other internet access to perform the transfer, but please consider both cases of traveller A having and not having similar access at the time.</p>
<p>What are the risks of such a deal, and what can be done to improve the chances of a successful deal?</p>

Derived functors in the category of sheaves. <p>I am studying derived functors and I came across a problem: given an additive left exact functor $F$ between two abelian categories $\mathcal{C}, \mathcal{D}$ with enough injectives one defines its right derived functor $RF : D^{-}(\mathcal{C}) \rightarrow D^{-}(\mathcal{D})$ by means of the universal property. Moreover one can define the <em>classical derived functors $R^{i}F(X) = H^{i}(RF(\mathcal{I}^{\bullet}_{X}))$</em> where by $\mathcal{I}^{\bullet}_{X}$ I mean an injective resolution of $X$.</p>
<p>As far as I understood $R^{i}F$ is meant to be a functor between $\mathcal{C}$ and $\mathcal{D}$, but here comes my question: if I consider $\mathcal{C} = \mathcal{D} = \{ \text{ sheaves of abelian groups on a topological space } \}$ then the cohomology groups of a complex of abelian sheaves need not to be abelian sheaves but only presheaves, so we need to sheafify. Is my reasoning correct or I am losing something?</p>
<p>Thank you.</p>

<p>I would like to do the same in another column for the latest date.</p>

How to create a symbol for LMB (left mouse clicking) or RMB (right mouse clicking) in LaTeX?. <p>I'm searching now since 2 weeks for a LMB (left mouse click) or
RMB (right mouse click) symbol in LaTeX. I saw it once
in a manual, but I couldn't find it any more...</p>
<p>Now I want to write a manual and for easier understanding how to
use the software it would be great to integrate such easy symbols!</p>
<p>I already designed the symbol in illustrator. but now I don't know
how to import it into LaTeX or how to design with "special" packages
the symbols?!?</p>
<p>Picture is missing cause I'm new and I am not allowed to upload pictures.</p>
<p>It should look like an oval. In the oval on the top there is a reversed T.
if it should be the "left mouse click" the left side is black. If it should
be the "right mouse click" then the right side is black.</p>
<p>Hope the description is sufficient. If not, post and I'll send you the image.</p>

How does Physical RAM affects file copy?. <p><strong>My setup:</strong></p>
<p><em>Source and destination Servers (installed in M1000e Dell enclosure):</em></p>
<ul>
<li>Dell Poweredge M620 (Blade servers) </li>
<li>2x Intel E5-2650 @ 2GHz

Restricting access using IP address / Network Redirection?. <p>I have a situation where we have a web server (lets call it A) that is hosting a set of HTTP based services.</p>
<p>Due to some client requirements, this web server is not open to the outside world but rather has an IP address based restriction to allow only a certain fixed set of IP addresses.</p>
<p>The idea is that there will be another server that will be the outward public facing server (lets call it B) and this server will then redirect all requests to server A - which accepts requests only from Server A.</p>
<p>2 questions :-</p>
<ol>
<li>Does having such a server configuration add any value or any benefit which could not be achieved by just having "server A" alone?</li>
<li>If "server B" is only basically doing a redirect, can I do it using some networking hardware itself like a router etc rather than having a web server do it? And would that be more efficient?</li>

22[M] and 22[F].... Scared she will break up with me after a 3 year relationship...What do I do?. So let me just give some background information, me and my girlfriend have been dating over 3 years, and I love her a lot. But things lately havent been great I started working in a pub full time over, and she works in a office which means that we never see each other except for like maybe 3 hours a week on a afternoon I'm off, cuase I have week days off when she works until 6 and she has weekends off but I work until midnight then.
Before we used to see each other on the weekends before I got this job, for two days. Which was nice to spend time with her, anyway we been like a month in this situation lucky for me she was gonna quit her job soon cuase she wants to apply for some schemes as she doesn't like her current job. Which for me is good cuase I get to see her again.
So the real issue happen yesterday when we went out, we had a big fight. We went out as a group with some of her friends and mine. The fight started cuase she was talking and being friendly with a guy at the bar right in front of me. Now she didn't think it was a big deal but for me it was but when I tried to tell her about it she would just essentially run away to the bathroom and come back and pretend everything was fine. Which annoyed me quite a bit. I was going to drop it since she clearly didn't think it was a big deal but she kept on asking me what's wrong until I finally told her. To which she replied before I could explain why that annoyed me that I don't trust her and stormed off to the bathroom. I then sent her friend to check on her to see if she was alright and just went to get some water. When she came out of the toilet she just went home with her friend. She seemed upset but there wasn't much I could have said at that point cuase she clearly didn't't want to speak to me.
Now just to clarify I trust her and I trust her a lot, but lately she been acting a bit weird. I will just give some examples she went out one night a couple of weeks ago and was talking about how guys were hitting on her and I was like haha the wankers kind of thing and then she said something stupid like Ohhh see I have other options which I was like wait what?? When I asked her about it she said it was just a bad joke. Which I didn't get and still don't get she also been quite snappy with me which is weird. And the last really weird thing was that she always complains to me that she doesn't have any friends at work even though she was texting with a guy from work, which she made it seem like was just a colleague I asked her she didn't even mention that she was talking to him outside work and she said I was going to cuase you might find out anyway(i did cuase she got a message from him whilst I was with her) but she didn't't want to upset me. Now don't get me wrong she wasn't flirting with him or anything just didn't understand why she made it seem like she talked to no-one from work and she felt the need to hide this from me.
So yesterday I got annoyed and not cuase I don't trust her, but because for me its not nice to see my girlfriend being friendly with other guys right infront of me. That just annoys me and she knows that which is why I didn't understand why she would do it in the first place. Like for me if I talk to another woman in a bar or if another woman approaches me I just end the conversation as quickly as possible cuase I don't need to talk to random women who are trying to hit on me. But my girlfriend still get jealous and stuff which I'm like I get it I don't like it too. But the thing is when she does its meant to be fine cuase I have to trust her and that double standard annoys me.
So right now she said to me she needs time to think stuff over.... which sounds like she wants to break up with me. So what should I do?

<p>I can get the Ubuntu-PC's external network IP like "183.192.20.118" and I also know the intranet IP like 10.10.0.132, but if I try to connect the Ubuntu-PC , I need know the the port number.</p>
<p>For example, I run ssh on Ubuntu-PC, the ssh use port 22 on Ubuntu-PC. HOW do I know which port on the route to connect? LIKE 183.192.20.118:xxxx
what the xxxx should be?</p>
<p>I can write some basic Java program on the Ubuntu-PC, and I can get some infomation by using NAT penetration software.</p>
<p>So how do I achieve THAT: connect the Ubuntu-PC by Internet without setting the route?</p>

Script acts differently in different directories. <p>I have a simple script that I pulled out of a larger script dedicated to renaming files with odd characters in the name. I have run this successfully on the same machine within different directories, and as we speak, it is running successfully within a directory but for some reason when running it against a higher level directory it renames the files incorrectly.
For example I have run this against a folder called UnsortedMusic.
What it is supposed to do is: </p>
<pre><code>/UnsortedMusic/Dir 001/SubDir 001/Song To Sing.flac > /UnsortedMusic/Dir 001/SubDir 001/SongToSing.flac
</code></pre>
<p>it takes the spaces out of the name, I then have essentially the same code but dedicated towards directories to remove spaces in directory names: </p>
<pre><code>/UnsortedMusic/Dir 001/SubDir 001/SongToSing.flac > /UnsortedMusic/Dir001/SubDir001/SongToSing.flac
</code></pre>
<p>This has worked successfully on other directories but for some reason on one particular dir it is doing someting like this: </p>
<pre><code> /UnsortedMusic/Dir 001/SubDir 001/Song To Sing.flac > /UnsortedMusic/Dir001/SubDir001/UnsortedMusicDir001SubDir001SongToSingflacSongToSingflac
</code></pre>
<p>As you can see its not only renaming the file with all the directory names its also removing the "." in the .flac which means ill have to change this manually for thousands of files. </p>
<p>This snippet of code is listed below: </p>
<pre><code>#!/bin/bash
#set -e
FolderName="Unsorted" #Dir location to be sorted
# Log Location on Server.
LOG_LOCATION=$(pwd) #/home/user/scripts/logs
exec > >(tee -i $LOG_LOCATION/RenameFile.log)
exec 2>&1
Start by seeing if the new directory allready exists, if not, make it
echo "Looking in $FolderName for files with abnormal characters"
#Rename any directories that might have a weird name structure that could conflict
find ${FolderName} -type f \( -name "* *" -o -name "*(*" -o -name "*[*" -o -name "*&*" \) -print0 | sort -rz | while read -d $'\0' file;
do
mv -v "$file" "$(dirname "$file")/$(basename "${file//[^a-zA-z0-9_-.]/}")";
done
#echo "Log Location should be: [ $LOG_LOCATION ]"
echo "Finished Process"
</code></pre>
<p>Which is part of a larger process script shown below: </p>
<pre><code>#!/bin/bash
#set -e
NewDirName="TestDirV2" #New Dir name
FolderName="TestDir" #Dir location to be sorted
# Log Location on Server.
LOG_LOCATION=$(pwd) #/home/user/scripts/logs

then

do

done
for FileType in $(find $FolderName -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u)
do

then

echo "File to move ${FileToMove##*/}"

echo "Checking to see if $SpecificFile already exist in $NewDir"

then
x=0
while [ -f ${NewDir}/${SpecificFile} ]
do
echo "File ${SpecificFile} already exists, renaming"
SpecificFile=${x}${SpecificFile}
x=$(( x++ ));
echo "Renamed to $SpecificFile"
done

collection view cells not loading images correctly. <p>I'm developing an iOS application that loads posts from a server into a UICollectionView. The collection view cell includes a UIImageView that is fixed to the bottom of the cell. </p>
<p><a href="https://i.stack.imgur.com/Q2uk5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Q2uk5.png" alt="UICollectionViewCell"></a></p>
<p>Whenever I start the application and the collection view loads, all the images do not load correctly but for the last image, which is the correct dimensions. All cells are being formatted the same way. </p>
<p><a href="https://i.stack.imgur.com/g65X0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/g65X0.png" alt="UICollectionView"></a></p>
<p>I have tried a multitude of solutions but nothing so far has worked.</p>
<p>What I suspect is happening is that the images have not finished loading before being set to the UIImageView of each cell (except for the last one in this case). This doesn't seem possible though as the cells are reloaded after getting a successful response..</p>
<p>This is my code for that particular function (using Alamofire)</p>
<pre><code>func getAllPosts(){
let url = "\(Constants.baseURL)/posts/"
let parameters = ["user_id": "\(userProfile!.getId())"]
Alamofire.request(.POST, url, parameters: parameters, encoding: .JSON)
.validate(contentType: ["application/json"])
.responseString { response in
switch response.result {
case .Success:
var postsArray = Array<[String: AnyObject]>()
do {
let json = try NSJSONSerialization.JSONObjectWithData(response.data!, options: NSJSONReadingOptions.MutableContainers)
for post in json as! [AnyObject] {
postsArray.append(post as! [String: AnyObject])
}
//invert array of posts so that latest load first!
postsArray = postsArray.reverse()
} catch {
}
//convert json to Post objects and reload the view
self.initialisePosts(postsArray)
self.collectionView?.reloadData()
case .Failure(let error):
print(error)
}
}
}
</code></pre>
<p>All help is appreciated.</p>
<p>Edit: Below are the current constraints on the UIImageView</p>
<p><a href="https://i.stack.imgur.com/JPfB6.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JPfB6.png" alt="Constraints"></a></p>
<p>Edit 2: Here is the code for formatting the cells</p>
<pre><code>override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
// get a reference to our postcell with no image
let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifiers[0], forIndexPath: indexPath) as! PostCell
guard let _: Post? = posts[indexPath.row] else {
return cell
}
return configurePostCell(cell, post: posts[indexPath.row])!
}
func configurePostCell(cell: UICollectionViewCell, post: Post) -> PostCell?{
if let cell = cell as? PostCell {
cell.author.text = post.user_name
cell.date.text = formatter.stringFromDate(post.pub_date!)
cell.desc.text = post.desc
cell.layer.cornerRadius = 5 //set corner radius here
cell.advertImage.image = post.advert?.advert_image
return cell
}
return nil
}
</code></pre>
<p><strong>Update: Using @Michael's Advice I have found that the Cell images <em>are</em> loading correctly..</strong></p>
<p><a href="https://i.stack.imgur.com/8uWw1.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8uWw1.jpg" alt="Correctly loading image"></a></p>

multi-thread CPU usage in C#. <p>My Program uses predetermined number of threads that each do independent work.
I use i7-2600 CPU but I shut down the hyper-thread module so it runs 4 threads on 4 cores.
When I run the program with 1 thread the CPU usage is 25% which is perfect since 1 thread is fully used, but when I run 4 or 3 thread I only get 60% CPU, why?</p>
<p>Like I mentioned before the threads are totally independent (there are no locks and no contentions) also when I run the program 4 times with 1 thread I get 100% CPU usage (i.e. when its 4 processes of 1 thread for each process I get proper CPU usage)</p>
<p>Any ideas?</p>
<p>some more info:</p>
<ol>
<li>I'm not using I/O while processing all the needed data is loaded into to the memory, each thread loads its own data prior to processing.</li>
<li>I do load the data from a database (using oleDb) but the issue I'm describing happens after the loading while all threads are processing (no loading is done).</li>
<li>The numbers are:
<ul>
<li>2 threads around 40% instead of 50 (85% for each thread).</li>
<li>3 threads around 50% instead of 75 (65% for each thread).</li>
<li>4 threads around 60% instead of 100 (60% for each thread).</li>
</ul></li>
<li>I use i7 2600 with 16GB memory but the memory usage on that process doesn't come close to that.</li>
<li>I ran windows performance monitor to look for contentions there are none.</li>

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>

Nested generic syntax ambiguity >>. <p>Apparently, C# is as susceptible to '>>' lexer dilemma <a href="https://stackoverflow.com/questions/5771131/nested-templates-vs-shift-operator">as is C++</a>.</p>
<p>This C# code is pretty valid, it compiles and runs just fine:</p>
<pre><code>var List = new Dummy("List");
var Nullable = new Dummy("Nullable");
var Guid = new Dummy("Guid");
var x = List<Nullable<Guid>> 10;
var y = List<Nullable<Guid>> .Equals(10,20);
</code></pre>
<p>You'd have to overload '<' and '>>' operators for the Dummy class above.</p>
<p>But the compiler manages to guess that in 'x' case the meaning is to use List, Nullable and Guid local variables. And in 'y' case it suddenly decides to treat them as names of well-known types.</p>
<p>Here's a bit more detailed description with another example:
<a href="http://mihailik.blogspot.co.uk/2012/05/nested-generics-c-can-be-stinky.html" rel="nofollow noreferrer">http://mihailik.blogspot.co.uk/2012/05/nested-generics-c-can-be-stinky.html</a></p>
<p>The question is: how does C# compiler resolve 'a<b<c>>' to arithmetic expression or generic type/method?</p>
<p>Surely it doesn't try to have multiple 'goes' over the text of the program until it succeeds, or does it? That would require unbounded look-ahead, and a very complex too.</p>

comparing cubics. <p>Suppose I have cubic functions $$f(t)=a_0+a_1t+a_2t^2+a_3t^3$$ and $$g(t)=b_0+b_1t+b_2t^2+b_3t^3$$ where $t\geq 0$.</p>
<p>Let $$h(t)=f(\alpha t)+g((1-\alpha)t), \alpha\in[0,1].$$ What conditions do I impose on the coefficients of $f$ and $g$ for $$(1)\space{} h(t)\geq f(t)?$$ $$(2)\space{} h(t)\geq g(t)?$$</p>
<p>Initially, in (1) I considered that $h(t)-f(t)\geq 0$. But I got stuck because I cannot infer from there that the coefficients of $h(t)-f(t)$ would each be greater than or equal to zero, right? Is there a special theory that needs to be used to solve this kind of problem?</p>

Why are some computers are slow during file copy process?. <p>I have a modern laptop (quad-core i5 2.5GHz, 4GB RAM, ) at work. But it is very slow and unresponsive when I copy files in the background.On the other side, at home I have a simple 2-core PC (E2180 2 GHz CPU, 2GB RAM) and I do not observe any reduction of the performance whenever I copy anything. Both computers have similar HDDs installed and both tested using same file systems, operating systems and drivers. So, I am trying to understand what can cause such performance drop. Is it a typical problem of all laptops? According to PassMark chart table my PC should be 2-times slower than my laptop, but it's not the case: my PC is much faster under high I/O load. Do you know any reliable performance chart which takes into account this kind of tasks (file copy, I/O)? </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:

Prove that $ \sqrt{5} $ is irrational geometrically Hardy and Wright. <p>I am reading Hardy and Wright's Intro to Number Theory chapter about irrational number and there is a section proving that $ \sqrt{5} $ is irrational geometrically, but the proof is confusing me for some parts. The proof, extracted verbatim from the book, is presented below for convenience.</p>
<p>$ \textbf{Proof} $: We argue in term of $ \displaystyle x = \frac{\sqrt{5} - 1}{2} $. Then $ x^2 = 1 - x $. Geometrically, if $ AB = 1, AC = x $, then $ AC^2 = AB.BC $ and $ AB $ is divided in golden section by $ C $. (For the geometric figure, see <a href="https://books.google.com/books?id=P6uTBqOa3T4C&pg=PA52&lpg=PA52&dq=If%20we%20divide%201%20by%20x,%20taking%20the%20largest%20possible%20integral&source=bl&ots=Bevhw_eyfm&sig=GSU-KD5dWRyW5qIaKShrIcf1y7g&hl=en&sa=X&ved=0ahUKEwjdyJ7qmOTSAhXmIsAKHVKDAUQQ6AEIGjAA#v=onepage&q=If%20we%20divide%201%20by%20x%2C%20taking%20the%20largest%20possible%20integral&f=false" rel="nofollow noreferrer">Fig 4 here</a>.)</p>
<p>If we divide $ 1 $ by $ x $, taking the largest integral quotient, viz. $ 1 $, the remainder is $ 1 - x = x^2 $. If we divide $ x $ by $ x^2 $, the quotient is again $ 1 $ and the remainder is $ x - x^2 = x^3 $. We next divide $ x^2 $ by $ x^3 $, and continue the process indefinitely; $ \textbf{at each stage the ratios of the number divided,} $
$ \textbf{the divisor, and the remainder are the same.} $ I am confused about this bold sentence. I work out a few examples and I got:</p>
<p>$ 1 = 1.x + (1 - x) = 1.x + x^2 $</p>
<p>$ x = 1.x^2 + (x - x^2) = 1.x^2 + x^3 $</p>
<p>$ x^2 = 1.x^3 + (x^2 - x^3) = 1.x^3 + x^4 $</p>
<p>and so on, so the ratios of the number divided, the divisor, and the remainder are all $ \displaystyle \frac{1}{x} $, is that what they are implying here?</p>
<p>Continue the proof: </p>
<blockquote>
<p>Geometrically, if we take $ CC_{1} $ equal and opposite to $ BC $, $ AC $ is divided at $ C_{1} $ in the same ratio as $ AB $ at $ C $, i.e. in golden section; if we take $ C_{1}C_{2} $ equal and opposite to $ C_{1}A $, then $ C_{1}C $ is divided in golden section at $ C_{2} $; and so on. Since we are dealing at each stage with a segment divided in the same ratio, the process can never end.</p>
</blockquote>
<p>I currently stuck on this paragraph, what do they mean by "$ AC $ is divided at $ C_{1} $ in the same ratio as $ AB $ at $ C $?" At first I thought this means $ \displaystyle \frac{AB}{AC} = \frac{AC}{AC_{1}} $, but this is not true since $ \displaystyle \frac{AB}{AC} = \frac{1}{x} $ while $ \displaystyle \frac{AC}{AC_{1}} = \frac{x}{2x - 1} $.</p>
<p>Continue the proof: </p>
<blockquote>
<p>If $ x $ is rational, then $ AB $ and $ AC $ are integral multiples of the same length $ \delta $, and the same is true for $ C_{1}C, C_{1}C_{2}, \dots $, i.e. all the segments in the figure. Hence, we can construct an infinite sequence of descending integral multiples of $ \delta $, and this is plainly impossible.</p>
</blockquote>
<p>If $ x = AC $ is rational, then $ \displaystyle AC = \frac{a}{b} $ and $ AB = 1 $, then how can "$ AB $ and $ AC $ are integral multiples of the same length $ \delta $?"</p>
<p>Any insight is appreciated.</p>

Multiple inheritance and unique_ptr destruction. <p>I have the classic (possible problematic) multiple inheritance diamond scheme.</p>
<ul>
<li>B inherits A</li>
<li>C inherits A</li>
<li>D inherits C and B</li>
</ul>
<p>I want to have a <code>std::vector</code> that can contain either <code>C</code> or <code>D</code>
objects so I make it as <code>std::vector<C></code> which is <code>D</code>'s dad and it
works fine.</p>
<p><strong>BUT</strong> when I use: <code>std::vector<std::unique_ptr<C>></code> then I have segmentation fault upon the destruction of the vector.</p>
<pre><code>** glibc detected *** ./a.out: free(): invalid pointer: 0x0000000009948018***
</code></pre>
<p>Why is there a difference? To me, even the first implementation is problematic.</p>
<p><strong>Code</strong></p>
<pre><code>#include <string>
#include <vector>
#include <memory>
class A
{
public:
A() = default;
};
class B : public virtual A
{
public:
B() = default;
};
class C : public virtual A
{
public:
C() = default;
};
class D : public B, public C
{
public:
D() = default;
};
int main()
{
{ // this crashes
std::vector<std::unique_ptr<C>> v;
std::unique_ptr<D> s1(new D());
v.push_back(std::move(s1));
std::unique_ptr<C> s2(new C());
v.push_back(std::move(s2));
}
{ // this is fine
std::vector<C> v;
D s1;
v.push_back(s1);
C s2;
v.push_back(s2);
}
return 0;
};

How to raise a LaTeX warning from within Lua code?. <p>I want to raise a warning from within Lua code. With advice from the <a href="http://wiki.luatex.org/index.php/Writing_Lua_in_TeX#Backslash">LuaTeX wiki</a> and <a href="http://texdoc.net/pkg/clsguide">LaTeX 2𝜀 for class and package writers</a>, I arrived at the following (working) solution:</p>
<pre><code>\documentclass{article}
\begin{document}
Foo
\directlua{
myvar = "\noexpand\\PackageWarning{mypackage}{Hello, I am a warning.}"
tex.print(myvar)
}
\end{document}
</code></pre>
<p>This seems unnecessarily complex, considering that raising an error is as easy as:</p>
<pre><code>\directlua{
tex.error("Hi, I'm an error!")
}
</code></pre>
<p>While I'm aware that <code>tex.error</code> is a generic TeX error and the warning I'm producing is a package-specific warning, I still think for both generic LaTeX warnings (if that exists?) and package-specific warnings (as well as package-specific errors, probably), there should be an easier way. Is there one?</p>
