What are the advantages and disadvantages of different types of motion sensors?. <p>I understand there are a number of different motion sensor technologies out there, including Active Infrared (AIR), Passive Infrared (PIR), Microwave and Ultrasonic motion sensors. </p>
<p>I would like to know what the advantages and disadvantages of these different types of motion sensors are and what (if any) vulnerabilities exist in them. </p>
<p>Additionally, have I overlooked any other similar motion sensing devices?</p>
<hr>
<p>Edit: just to clarify, human based motion sensors is what im interested in. Practical, non-theoretical technologies. This question isn't to do with vibration sensors, glass break sensors etc</p>
<p>Edit: To limit the scope somewhat, lets stick to more common types of motion sensors rather than exotic situation specific types?</p>

Definition of $C^1_c((a,b);H)$. <p>Can I define $C^1_c((a,b);H)$ as space of compactly-supported continuous functions from $[a,b]$ to a Banach space $H$ with compactly supported derivative (that may not be continuous)? So basically I am not saying "continuously differentiable." Would it make sense at all?</p>

Question on numbers modulo $(n+1)!$. <p>I just noticed the following surprising 'fact' (it holds at least for low values of n):</p>
<p>Pick any number k < $(n+1)!$</p>
<p>Consider the n products $ki$ with $1 \le i \le n$, i.e. $k, 2k, ... nk$ modulo $(n+1)!$.</p>
<p>In at least one of these cases, this modulus will at either:</p>
<ul>
<li>be at most $n!$, or</li>
<li>be at least $(n+1)! - n!$</li>
</ul>
<p>So basically it will lie in the range $[-n!, n!]$ modulo $(n+1)!$.</p>
<p>For example, let n = 5.
Here, $(n+1)! = 720$.</p>
<p>Pick a random number in $[0, 720]$, say $489$. We get $n = 5$ products:</p>
<ul>
<li>$489 * 1 \mod 720 = 489$</li>
<li>$489 * 2 \mod 720 = 258$</li>
<li>$489 * 3 \mod 720 = 27$</li>
<li>$489 * 4 \mod 720 = 516$</li>
<li>$489 * 5 \mod 720 = 285$</li>
</ul>
<p>Although we managed to escape in four cases, with $i=3$ we ended up with a residue of $27$ which lies between $-120$ and $120$.</p>
<p>Any ideas on how to prove that this will always happen? Or maybe a counter-example?</p>

Partitions that separate all subsets. <p>Let $A=\{1,2,\dots,n\}$ and let $\mathcal{A}_1,\dots,\mathcal{A}_k$ be partitions of $A$ into two sets. Suppose that for each subset $B\subseteq A$ of even size, there exists a partition $\mathcal{A}_i$ such that half the elements of $B$ is in one part of the partition and the other half is in the other part. What is the minimum possible $k$ for which this is possible?</p>
<p>An asymptotic bound for $k$ would already be good enough. For example, can we use just $k=O(n)$ partitions? Or even some polynomial in $n$ partitions?</p>
<p>If we only consider subsets $B$ of size two, then we can do it with $\log n$ partitions by writing each element of $A$ in base two and have $\mathcal{A}_i$ be the partition according to whether the $i$th digit is $0$ or $1$. However this does not work when $B$ is of arbitrary size: For example among the four numbers $001,010,011,111$, none of the digits has $0$ and $1$ appearing twice each.</p>

60% CPU Usage just moving my mouse around | Ubuntu 18.04. <p>So last night I decided to return to Linux after reviewing the way Microsoft manufactures consent for surveillance type behaviour on their Windows operating system.</p>
<p>I'm having a problem with high CPU usage just moving around my mouse in Firefox I get 30% CPU usage and 30% web content usage which seems a tad high for my CPU which is actually an AMD A10-4655m APU with Radeon HD graphics × 4. This problem also occurs just moving my mouse over the dock icons to the left which causes the CPU usage to spike to 30% also for gnome-shell.</p>
<p>The machine feels sluggish, I have looked in the additional drivers area but there are no additional drivers available and I am kind of stuck from where to go from here so I am relying on your kind responses.</p>
<p>There is actually a post from 2012 <a href="https://askubuntu.com/questions/166538/problems-with-ubuntu-and-amd-a10-4655m-apu">here</a> which tells you how to install proprietary drivers but on installation I did check the mark to install 3rd party drivers at the point of installation.</p>
<p>Is there any way to fix this problem and give me a bit of speed so I can stick with Ubuntu. Thank you for taking the time to help me out in advance.</p>

A question about carbonated drinks and pressure. I have a hypothesis. If you put a carbonated drink in low pressure, say by squeezing the plastic bottle, screwing on the cork and releasing the bottle to try to straighten itself out again, the CO2 will form large bubbles quicker, escaping the soft drink and turning it stale sooner than usual.
Could this be true reddit?
I heard the opposite suggested as a method of *preserving* the CO2 in the bottle, but it sounded a bit strange to me. | 0non-cybersec

HD images on eCommerce and SEO. <p>I have an eCommerce website where product images are currently resized to 250x250 max and shown to the user. I shrink the original high-definition images to a size that makes it possible for the page to load quickly.</p>
<p>This is what is currently being done:</p>
<ul>
<li>Images are part of the Product microdata information.</li>
<li>Every product image is listed on my website's sitemap.xml</li>
<li>The product image is loaded via an IMG tag.</li>
</ul>
<p>I want to take advantage of the HD version that I keep on my server, and show it to users in a friendly way, but also want to help images rank.</p>
<p>How can I get Google to associate my image in the most SEO friendly way? I could possibly replace the image on the sitemap with the HD version.</p>
<p>However, what bothers me is that I can't seem to do the same for the Product snippet, since Google hates hidden content, and I certainly don't want the HD image to be loaded when the product page is loaded. Are there any alternatives to actually loading the full-sized image?</p>

Definition of a Manifold from Guillemin Pollack. <p>I have been studying differential topology from Guillemin and Pollack (GP).
Unlike many other books that define differentiable manifolds using maximal atlases GP starts by saying $ X \subset R^{N}$ for some ambient space $R^{N}$ and then goes on to define a $k$ dimensional manifold. But I know that this containment comes due to a weak version of Whitney's theorem.</p>
<p>Later on when they prove Whitney's theorem it is done so by induction on $N >= 2k+1$. But how to I justify that $ X \subset R^{N}$ in the first place? How can it just be assumed in definition like that?</p>
<p>I need help getting from the general definition of manifolds using atlases to the weak version of Whitney.</p>
<p>Thanks</p>

Doctrine 2.1 where foreign key id =?, edit: Fixed in Doctrine 2.2. <p>I've looked at a lot of answers here related to what seems to be a serious lack of functionality in Doctrine 2.1 that may be the result of OOP correctness trumping relational sanity. </p>
<p>I have two tables with a many to one relationship, Articles and Members. A Member can have many published Articles. The annotation on the owning side is</p>
<pre><code>/**
* @var \Member
* @ORM\ManyToOne(targetEntity="Member")
* @ORM\JoinColumns({
* @ORM\JoinColumn(name="member_id", referencedColumnName="id")
* })
*/
private $member;
</code></pre>
<p>I want to get all active articles for member 6, this is a simple query in SQL: </p>
<pre><code>SELECT * FROM mbr_article
WHERE active = 1 AND member_id = 6
ORDER BY article_id DESC
</code></pre>
<p>What I ended up with was </p>
<pre><code>$rep = $this->getDoctrine()->getRepository('SMWMemberBundle:Article');
$q = $rep->createQueryBuilder('a')
->leftJoin('a.member','m')
->where('m.id = ?1')
->andWhere('a.active = 1')
->orderBy('a.id', 'DESC')
->setParameter(1, $id)
->getQuery();
</code></pre>
<p>which generated</p>
<pre><code>SELECT m0_.id AS id0, m0_.active AS active1, m0_.update_time AS update_time2,
m0_.content AS content3, m0_.member_id AS member_id4
FROM mbr_article m0_
LEFT JOIN mbr_member m1_ ON m0_.member_id = m1_.id
WHERE m1_.id = ? AND m0_.active = 1
ORDER BY m0_.id DESC
</code></pre>
<p>which works and probably isn't much slower, but that JOIN is not needed as I already have the Member object. When I tried it the other way, I got all Articles not just active ones. </p>
<p>I've seen responses such as <a href="https://stackoverflow.com/questions/8211679/can-you-get-a-foreign-key-from-an-object-in-doctine2-without-loading-that-object">Can you get a foreign key from an object in Doctine2 without loading that object?</a> that use <code>getEntityIdentifier</code> and mentions improvements coming in the 2.2 where I could say <code>IDENTITY(member)</code>. </p>
<p>Is there a reasonable way to do this in Doctrine 2.1? Will the enhancement allow <code>andWhere('IDENTITY(member) = ?')</code> in the query builder? </p>
<p>Edit:</p>
<p>Thanks to @Ocramius, ->where('IDENTITY(a.member) = ?1') does work in Doctrine 2.2</p>

Proof that $\frac{1}{2} > 0$ using order properties of $\mathbb R$. <p>Let <span class="math-container">$\mathbb P$</span> be a non-empty subset of <span class="math-container">$\mathbb R$</span> such that for all <span class="math-container">$a, b \in \mathbb P$</span>,</p>
<ul>
<li><span class="math-container">$a + b \in \mathbb P$</span></li>
<li><span class="math-container">$ab \in \mathbb P$</span></li>
<li>Exactly one of the following holds:
<span class="math-container">$a \in \mathbb P$</span>, <span class="math-container">$-a \in \Bbb P$</span>, <span class="math-container">$a = 0$</span>.</li>
</ul>
<p>I already know that <span class="math-container">$n > 0$</span> for all <span class="math-container">$n\in \mathbb N$</span>. How do I show that <span class="math-container">$\frac{1}{2} > 0$</span>, or, in general, <span class="math-container">$\frac{1}{n} > 0$</span>? My initial attempt at doing this was to assume by contradiction that <span class="math-container">$\frac{1}{2} < 0$</span>. Then by definition, <span class="math-container">$-\frac{1}{2} \in \mathbb P$</span>. My question is, can I assume that <span class="math-container">$-\frac{1}{2} - \frac{1}{2} = -1$</span> if I'm basing this on the algebraic properties of <span class="math-container">$\mathbb R$</span> where <span class="math-container">$\mathbb R$</span> is treated as a field?</p>
<p>For instance, although it's obvious that <span class="math-container">$1*0 = 0$</span> in common sense math, in field theory, it is proven rigorously (a.k.a the annihilator property). Does a similar idea apply for other numbers in the field, for instance, the number <span class="math-container">$\frac{1}{2}$</span>?</p>
<p>Thanks in advance.</p>

What are those nul bytes doing in Certificate Subject CN?. <p>While doing some research with SSL certificates, I found some weird certificates containing nul bytes in their Subject field. One example is <code>www.refah - bank.ir</code> (did the Iranian government fake this CA? It looks very similar to a Spanish CA except for location...).</p>
<p>Another example is <code>mcafee.com</code> which looks more trustworthy to me. They have two different IP addresses for <code>mcafee.com</code> and <code>www.mcafee.com</code>, the certificate also differs. What surprised me was that such a company uses certificates containing nul bytes in their Subject field:</p>
<pre><code>Data:

</code></pre>
<p>Opening <code>mcafee.com</code> correctly rejected the certificate as the wildcard does not match against this. Out of curiosity, I edited my host file and made <code>foo.mcafee.com</code> (and <code>www.</code>) point to the IP address 161.69.13.40 (mcafee.com).
I would expect such a certificate to be rejected, but Firefox and Chromium both accept this certificate.</p>
<p>I found another website that has nul bytes in the CN and is still "trusted": <a href="https://www.digiturk.com.tr">https://www.digiturk.com.tr</a></p>

SQL Server fulltext_semantic_languages. <p>When trying to install <a href="http://blogs.msdn.com/b/sqlfts/archive/2011/07/21/introducing-fulltext-statistical-semantic-search-in-sql-server-codename-denali-release.aspx" rel="nofollow">a semantic search example</a>, I'm running into a problem. </p>
<p>There are some steps in the example to check if the 'new' Semantic Search and Full Text Search are installed. </p>
<p>Executing the following T-SQL code returns the version '11.0.1153.1.1' of the semantic database. </p>
<pre><code>/* Verify the registration is succeeded */
SELECT * FROM sys.fulltext_semantic_language_statistics_database;
GO
</code></pre>
<p>And...the following T-SQL code returns 1, which indicates that Full-Text Search and Semantic Search are installed.</p>
<pre><code>/* Check if Full-Text Search and Semantic Search are installed*/
SELECT SERVERPROPERTY('IsFullTextInstalled');
GO
</code></pre>
<p>I also registered the 'language_statistics_db'. </p>
<pre><code>/* Register Language Statistics Database */
EXEC sp_fulltext_semantic_register_language_statistics_db 'semanticsdb';
GO
</code></pre>
<p>I'm executing the following T-SQL code to verify if the languages are installed correctly <em>(this is were something odd happens)</em>. </p>
<pre><code>/* Check available languages for statistical semantic extraction */
SELECT * FROM sys.fulltext_semantic_languages;
GO
</code></pre>
<p>This statement returns no rows, indicating that there are no languages installed. I tried reinstalling the database(s) but with no effect. </p>
<p>Can someone point out to me were I made a mistake?</p>
<p><strong>UPDATE</strong>: After unregistering the semantic_language database and registering it using 'master' it worked. No idea why this worked. <strong><em>Why? Someone?</em></strong></p>
<p>The code that worked for me:</p>
<pre><code>/ * Unregistar language db */
EXEC sp_fulltext_semantic_unregister_language_statistics_db
GO
</code></pre>
<p>And registering: </p>
<pre><code>/ * register_language db */
Use master

Subfigure float - caption above, and how to break figure over two pages. <p>Firstly, thanks a lot in advance for your help with this problem. I've looked long and hard but not found a solution anywhere. I am writing my PhD thesis in Lyx and love how it makes the formatting so smart and easy, but I am having real trouble with some of my figures. I have three things I would like to achieve:</p>
<p>1) I would like to make figures with several subfloats (to show the same combination of an image and a graph in each. (I'll attach an example to this email). It really is valuable to have all three subfloats under the same single figure heading.
The problem is that only two of my three floats fit on a page and the third one is started but gets lost off the bottom. I don't want to make the figures smaller so they fit. Can I persuade Lyx to split the figure over two pages (a bit like it does with long tables)?</p>
<p>2) I would like the captions of the subfigures ABOVE the figures. </p>
<p>3) I would like the gap between the subfigure legends and the images to be bigger (you can see how squashed up they are).</p>
<p>I'm using the following in my document preamble to justify the labels on the left.</p>
<pre><code>\usepackage{caption}
\captionsetup{labelfont=bf,format=plain,indention=0cm,
justification=raggedright,singlelinecheck=false}
</code></pre>
<p>I tried to upload a pdf of what happens to the figure but it took too long so perhaps you can take it on trust that the bottom of the figure and main figure legend disappears off the end of the page.</p>

Database design for products with bundles of products. <p>I am building a database system for my retail business. I have set some tables which are:</p>
<ul>
<li>Product</li>
<li>Purchase</li>
<li>Sales</li>
<li>Balance</li>
</ul>
<p>All are connected one another and are able to show my inventory level.</p>
<p>The problem I am having is I also sell bundles of products - that have different prices than their individual prices.<br>
Example: I sell an orange for $1, an apple for $1.2; I sell fruit package 1 (2 oranges and 2 apples) for $3.8, package 2 (4 oranges and 4 apples) for $7.</p>
<p>Is there a right way how to create relationship for these product bundles?</p>

Laravel changes created_at on update. <p>I found <a href="https://stackoverflow.com/questions/31842470/laravel-updating-row-changes-created-at-column">this answer</a> on the subject, but it doesn't work for me.</p>
<p>So, I make an entry in the database:</p>
<pre><code>// Write lead to database
$lead = Lead::create($lead_data);
</code></pre>
<p>And the timestamps look like this, which is good:</p>
<pre><code>| 2016-01-08 10:34:15 | 2016-01-08 10:34:15 |
</code></pre>
<p>But then I make a request to an external server, and I need to update the row:</p>
<pre><code>$lead->user_id = $response['user_id'];
$lead->broker_id = $response['broker_id'];
$lead->save();
</code></pre>
<p>and the created_at field gets changed:</p>
<pre><code>| 2016-01-08 04:34:17 | 2016-01-08 10:34:17 |
</code></pre>
<p>How do I solve this problem?</p>
<p><strong>EDIT</strong></p>
<p>I need a solution that would just modify the behavior without dropping columns or resetting migrations. The fix has to be performed on a live database without touching the data. As suggested below, I tried the following migration:</p>
<pre><code>$table->datetime('created_at')->default(DB::raw('CURRENT_TIMESTAMP'))->change();
</code></pre>
<p>but nothing happens. The created_at field still gets modified on update.</p>

Looking for a good exercise to help me get better at Multithreading. <p>I think of myself as a pretty decent developer, however when it comes to multithreading I'm a total n00b. I mean the only multithreading I've done at work was the very basic stuff like spawning off multiple threads using the ThreadPool to do some background work. No synchronization was necessary, and there was never any need to create threads manually.</p>
<p>So, my question is this; I want to write some application that will need to be heavily multithreaded and that will need to do all of the advanced things like synchronization etc.. I just can't think of anything to write. I've thought of maybe trying to write my own ThreadPool, but I think I need to learn to walk before I can run. So what ideas can anyone suggest? It doesn't have to have any real world useage, it can be totally pointless and worthless, but I just want to get better. I've read tons of articles and tutorials on all the theory, but the only way to REALLY get better is by doing. So, any ideas?</p>

Setting up a Godaddy SSL on CentOS?. <p>I've never set up an SSL on Linux before, but have a general idea of how it works. Server specs below if it helps:</p>

<p>So, I have 4 domains all of which share a single Magento installation and IP address. Assume one of my domains is "mywebsite1.com" I am trying to enable SSL just for this one domain for now, but I am running into errors. What am I doing wrong? Here's my work flow:</p>
<ol>
<li><p>I purchased an SSL from Godaddy then generated the csr and key with the command given by them:</p>

<li><p>I copy both the files to /etc/pki/tls/private</p></li>
<li><p>I open mywebsite1.crs then copy and paste the code to Godaddy. </p></li>
<li><p>I generate the crt files and download them from Godaddy, upload to my server, and then move them to /etc/pki/tls/certs</p></li>
<li><p>a. 1st try, I opened /etc/httpd/conf.d/ssl.conf and updated the
<em>default</em> VirtualHost block's SSLCertificate File, KeyFile, and ChainFile values to point to the correct locations. </p>
<p>b. 2nd try, following
<a href="http://dev.antoinesolutions.com/apache-server/mod_ssl" rel="nofollow noreferrer">http://dev.antoinesolutions.com/apache-server/mod_ssl</a> I modified
ssl.conf and added this directive: </p>
<p><code>NameVirtualHost *:443</code></p>
<p>c. Then I removed the entire <em>default</em> VirtualHost block (which was
quite lengthy).</p>
<p>Last attempt, I added the following to the modified ssl.conf from</p></li>

<li>I've read that you must enable ssl with a command called "a2enmod ssl" but that command does not exist for my server. </li>
<li>There are no ssl error logs in /etc/httpd/logs.</li>
<li>As per Godaddy, I was instructed to name the key "mywebsite1" without the extension. However, they give me a crt with the extension, which is odd.</li>
<li>This is only development phase and this change will need to be quickly reproduced with a new SSL and different domains once we launch the production server.</li>
</ol>
<p>I've tried all of the steps 3 times (see 5a-5c), but still no luck in getting the SSL to work for 1 of my domains. How can I get SSL to work?</p>
<p><strong>UPDATE: apachectl -S</strong></p>
<pre><code>12.34.567.90:80 mywebsite4.com (/etc/httpd/conf/httpd.conf:1021)
12.34.567.89:* is a NameVirtualHost
default server mywebsite3.com (/etc/httpd/conf/httpd.conf:1016)
port * namevhost mywebsite3.com (/etc/httpd/conf/httpd.conf:1016)
port * namevhost mywebsite1.com (/etc/httpd/conf/httpd.conf:1026)
port * namevhost mywebsite2.com (/etc/httpd/conf/httpd.conf:1031)
port * namevhost mywebsite5.com (/etc/httpd/conf/httpd.conf:1036)
wildcard NameVirtualHosts and _default_ servers:
*:443 is a NameVirtualHost
default server mywebsite1.com (/etc/httpd/conf.d/ssl.conf:77)
port 443 namevhost mywebsite1.com (/etc/httpd/conf.d/ssl.conf:77)
Syntax OK
</code></pre>
<p><strong>UPDATE: Got it working..but..</strong></p>
<p>I managed to get the SSL running by changing the vhost to just point to mywebsite1 instead of *:443</p>
<pre><code><VirtualHost mywebsite1.com>
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/mywebsite1.com.crt
SSLCertificateKeyFile /etc/pki/tls/private/mywebsite1.key
#SSLCertificateChainFile /etc/pki/tls/certs/gd_bundle.crt
DocumentRoot /var/www/html
ServerName mywebsite1.com
ErrorLog logs/ssl_error_log
TransferLog logs/ssl_access_log
LogLevel warn
</VirtualHost>
</code></pre>
<p>This pulls up the SSL, however... the HTTP protocol returns a "Bad Request" </p>
<p>This change seems to be affecting the non-ssl viewing of the site. I can't specify the port because restarting apache will give me an error that ports and non-ports can't be mixed.</p>
<p><strong>UPDATE</strong></p>
<p>Fixed with the suggestion by Michael Hampton. Thanks guys.</p>

Seagate's 30TB NAS with SimplyRAID configuration. <p>I recently bought a Seagate NAS Pro 6-Bay 30TB Network Attached Storage Drive (STDF30000100) from Amazon (<a href="http://rads.stackoverflow.com/amzn/click/B00LM6KVZA" rel="nofollow noreferrer">http://www.amazon.com/gp/product/B00LM6KVZA?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00</a>). It says it uses Seagate's SimplyRAID configuration. Unfortunately I could not find a clear explanation of how much space will I get if I opt for SimplyRAID as opposed to other RAID solutions. Can someone explain this to a newbie? Thanks.</p>

How do I know if I will be able to daisy-chain monitors? (connect two monitors to 1 DisplayPort). <p>I am planning to use <a href="http://en.wikipedia.org/wiki/Microsoft_Surface_Pro_2" rel="noreferrer">Surface Pro 2</a> with a dock station as my main computer and I would like to connect two external monitors to it, but <a href="http://www.microsoft.com/surface/en-us/support/hardware-and-drivers/docking-station" rel="noreferrer">the dock station</a> only contains a single DisplayPort socket. However, I see that <a href="http://en.wikipedia.org/wiki/DisplayPort#1.2" rel="noreferrer">DisplayPort 1.2</a> specification, approved in 2009, allows for daisy-chaining monitors through its <em>Multi-Stream Transport</em> feature.</p>
<p>How do I tell if I will be able to use two monitors in daisy-chain mode with my computer?</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:
