How much business logic should the database implement?. <p>I've worked in some projects where most of the business logic was implemented on the database (mostly through stored procedures). On the other side, I've heard from some fellow programmers that this is a bad practice ("Databases are there to store data. Applications are there to do the rest").</p>
<p>Which of these approaches is the generally better?</p>
<p>The pros of implementing business logic in the DB I can think of are:</p>
<ul>
<li>Centralization of business logic;</li>
<li>Independency of application type, programming language, OS, etc;</li>
<li>Databases are less prone to technology migration or big refactorings (AFAIK);</li>
<li>No rework on application technology migration (e.g.: .NET to Java, Perl to Python, etc).</li>
</ul>
<p>The cons:</p>
<ul>
<li>SQL is less productive and more complex for business logic programming, due to the lack of libraries and language constructs the most application-oriented languages offer;</li>
<li>More difficult (if possible at all) code reuse through libraries;</li>
<li>Less productive IDEs.</li>
</ul>
<p>Note: The databases I'm talking about are relational, popular databases like SQL Server, Oracle, MySql etc.</p>
<p>Thanks!</p>

What is `tic` and what can I do about it using 100% CPU?. <p>I have a process named <code>tic</code> that occasionally shows its ugly face in <code>htop</code> or Activity Monitor, consuming around 100% CPU. I couldn't find any good info on it last time I tried. What is it for, what would make it suck up my processor cycles, and what can be done about it. </p>
<p>I'm on the latest sub-version of Mojave: 10.14.3 (18D42).</p>
<p>Update: this happened again, and about 80% of the lines displayed by <code>sudo lsof -p PID</code> were related in some way to Visual Studio Code. I don't know if that's a useful clue for anyone about the cause... but I'll put it out there...</p>

Why can't this specific device be enumerated by UsbManager.getDevicesList()?. <p>As the title states, I am having troubles enumerating a specific USB device on a USB capable Android phone using UsbManager.getDeviceList(). I've had no trouble enumerating and communicating with other USB devices on this and other phones, but this specific USB device cannot be found. It also cannot be enumerated with 3rd party apps such as <a href="https://play.google.com/store/apps/details?id=aws.apps.usbDeviceEnumerator&hl=en" rel="nofollow noreferrer">USB Device Info</a>.</p>
<p>Below are the USB properties enumerated properly on a PC. I've communicated with the device manufacturer who has confirmed that an outside firm certified the device followed the USB 2.0 spec. Originally, my suspicion was that the device was rejected by Android because it omitted the following fields: iManufacturer, iProduct, and iSerialNumber, which were included by other compliant devices. However, it seems these fields aren't necessary after reviewing this excerpt from Section 9.5 of the <a href="http://www.usb.org/developers/docs/usb20_docs/" rel="nofollow noreferrer">USB 2.0 Spec</a>:</p>
<blockquote>
<p>Where appropriate, descriptors contain references to string descriptors that provide displayable information describing a descriptor in human-readable form. The inclusion of string descriptors is optional. However, the reference fields within descriptors are mandatory. If a device does not support string descriptors, string reference fields must be reset to zero to indicate no string descriptor is available.</p>
</blockquote>
<p>My question, then, is what is causing the UsbManager to reject enumeration of this USB device? And, more importantly, is there anything I can do about it to force Android to enumerate this device? Ideally, I am most interested in a solution that does not require root access, but it is not necessarily a deal-breaker.</p>
<p><a href="https://i.stack.imgur.com/qRIIC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qRIIC.png" alt="USB properties"></a></p>
<hr>
<p>EDIT: Some sample code.</p>
<pre><code>UsbManager usbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
HashMap<String, UsbDevice> deviceList = usbManager.getDeviceList();
// When I plug in this USB device, deviceList is empty.
// Other devices are discoverable, however.
</code></pre>
<hr>
<p>EDIT 2: I've tested with some more phones. I have successfully enumerated the USB device with the following phones:</p>
<ul>
<li>Note 2</li>
<li>LG-V400</li>
</ul>
<p>The following devices could not enumerate the device:</p>
<ul>
<li>Nexus 5</li>
<li>Galaxy S4, S5, S6</li>
<li>LG G2, 4G LTE</li>
</ul>
<hr>
<p>EDIT 3: <a href="https://gist.github.com/MikeOrtiz/92fc07d4761ce6e0b4d3" rel="nofollow noreferrer">Here are the logs</a> from calling <code>adb shell dmesg</code> on a Nexus 5 after plugging in the USB device. You can clearly see on lines 4-16 that the phone fails to enumerate the device.</p>

Side plank foot placement. First off, sorry if this has been talked about before, but I couldn't find it in the FAQ or exercise wiki.
My question is, are there any advantages or disadvantages to the different foot placements in the side plank?
I was first taught to perform it like this http://mandee.files.wordpress.com/2008/03/side-plank.jpg with one foot on the other, but if I am barefoot I feel like the bones in my feet are going to crumble
More recently I started doing it like this http://www.sparkpeople.com/assets/exercises/Side-Plank.gif just because I can hold it longer and my ankles don't go out before my obliques. Am I doing it wrong? Should I switch back to the foot on foot and deal with the pain or am I good doing the one foot in front of the other?

The Point of Hollandaise?. Okay, serious question, not trolling.
I've always felt like I've missed the point of hollandaise, specifically in the context of Eggs Benedict. It's a pain to make right and is basically just adding a redundant egg sauce to eggs. I also tend to batch-cook my dinners ahead of time (single dude on a budget!), and the fact that it doesn't keep makes experimenting with other hollandaise vehicles like asparagus or chicken somewhat impractical.
Since hollandaise is one of the classic sauces, I feel like I should learn how to do it right. What am I not understanding? Have I always had bad hollandaise? Is it just not to my taste?

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:

Quadratic equation with greatest integer functioin. <p>$[x]^2-7[x]+12=0$</p>
<p>find $x$?
where $[x]$ is Greatest Integer function </p>
<p>I have tried to solve the question like this:
putting $[x]=y$ , we have the equation:
$y^2-7x+12=0$
by solving this equation we get $y=3$ and $y=4$ </p>
<p>since $y=[x]$, therefore $[x]=3$ and $[x]=4$</p>
<p>according to the above statement we can say that $x=[3,5)$</p>
<p>I want to know weather my solution is correct or not.
and if it not correct then how to solve this equation.</p>

Rainbow Tables: What is the Reduction Used for?. <p>This is a follow up from <a href="https://security.stackexchange.com/questions/379/what-are-rainbow-tables-and-how-are-they-used/440#440">this answer</a>.</p>
<p>The answer is very good, and it put me to thinking and doing some research. I have found another good explanation on <a href="http://kestas.kuliukas.com/RainbowTables/" rel="nofollow noreferrer">this site</a>.</p>
<p>At some point, the author says:</p>
<blockquote>
<p>If the set of plaintexts is [0123456789]{6} (we want a rainbow table of all numeric passwords of length 6), and the hashing function is MD5(), a hash of a plaintext might be MD5("493823") -> "222f00dc4b7f9131c89cff641d1a8c50".
In this case the reduction function R() might be as simple as taking the first six numbers from the hash; R("222f00dc4b7f9131c89cff641d1a8c50") -> "222004".
We now have generated another plaintext from the hash of the previous plaintext, this is the purpose of the reduction function.</p>
</blockquote>
<p>However, I don't seem to have grasped the use of the reduction as it seems pretty arbitrary. How does reducing a hash to its first numbers help retrieving the plaintext. Is the choosing of the reduction (that is selecting the first few number of the hash) really arbitrary? Could I instead of taking the <strong>first</strong> six numbers use, say, the <strong>last</strong> six numbers?</p>

Stripe: webhook events order. <p>How should you handle the fact that events received via webhooks can be received in random order ?</p>
<p>For instance, given the following ordered event:</p>
<ul>
<li>A: invoiceitem.created (with quantity of 1)</li>
<li>B: invoiceitem.updated (with quantity going from 1 to 3)</li>
<li>C: invoiceitem.updated (with quantity going from 3 to 2)</li>
</ul>
<p>How do you make sure receiving C-A-B does not result in corrupted data (ie with a quantity of 2 instead of 3)?</p>
<p>You could <strong>reject the webhook if the previous_attributes in Event#data do not correspond to the current state</strong>, but then you are stuck if your local model was updated already, as you will never find yourself in the state expected by the webhook.</p>
<p>Or you can just use <strong>treat any webhook as a hint to retrieve and update an object</strong>. You just disregard the data sent by the webhook and always retrieve it.
Even if you receive events ordered as update/delete/create it should work, as update would in fact create the object, delete would delete it, and create would fail to retrieve the object and do nothing.
But it feels like a waste of resources to retrieve data each time when the webhook offers it as event data.</p>
<p>This question was <a href="https://stackoverflow.com/questions/31775335/stripe-webhooks-events-order">asked before</a> but the answers don't cover the above solutions.</p>

What specific algebraic properties are broken at each Cayley-Dickson stage beyond octonions?. <p>I'm starting to come around to an understanding of hypercomplex numbers, and I'm particularly fascinated by the fact that certain algebraic properties are broken as we move through each of the $2^n$ dimensions. I think I understand the first $n<4$ instances:</p>
<ul>
<li>As we move from $\mathbb{R}$ to $\mathbb{C}$ we lose ordering</li>
<li>From $\mathbb{C}$ to $\mathbb{H}$ we lose the commutative property</li>
<li>From $\mathbb{H}$ to $\mathbb{O}$ we lose the associative property (in the form of $(xy)z \neq x(yz)$, but apparently it's still alternative and $(xx)y = x(xy)$. Is that right?)</li>
<li>The move from $\mathbb{O}$ to $\mathbb{S}$ is where I start to get fuzzy. From what I've read, the alternative property is broken now, such that even $(xx)y \neq x(xy)$ but that also zero divisors come into play, thus making sedenion algebra non-division.</li>
</ul>
<p>My first major question is: Does the loss of the alternative property cause the emergence of zero divisors (or vice versa) or are these unrelated breakages?</p>
<p>My bigger question is: What specific algebraic properties break as we move into 32 dimensions, then into 64, 128, 256? I've "read" the de Marrais/Smith paper where they coin the terms pathions, chingons, routons and voudons. At my low level, any initial "reading" of such a paper is mostly just intent skimming, but I'm fairly certain they don't address my question and are focused on the nature and patterns of zero divisors in these higher dimensions. If the breakages are too complicated to simply explicate in an answer here, I'm happy to do the work and read journal articles that might help me understand, but I'd appreciate a pointer to specific papers that, given enough study, will actually address the point of my specific interest--something I can't necessarily tell with an initial glance, and might need a proper mathematician to point me in the right direction.</p>
<p>Thank you!</p>
<p>UPDATE: If the consensus is that this is a repeat, then ok, but I don't see how the answers to the other question about <em>why</em> algebraic properties break answers my questions about <em>what</em> algebraic properties break. Actually, the response marked as an answer in that other question doesn't actually answer that question either. It provides a helpful description of how to construct a multiplication table for higher dimension Cayley-Dickson structures, but explicitly doesn't answer the question as to why the properties break. </p>
<p>The Baez article many people suggest in responses to all hyper-complex number questions like mine is truly excellent, but is mostly restricted to octonions, and, in the few mentions it makes of higher dimension Cayley-Dickson algebras, does not refer to what properties are broken. </p>
<p>Perhaps the question isn't answerable, but in any case it hasn't been answered in this forum. </p>
<p>UPDATE 2: I should add that the sub question in this post about whether the loss of the alternative property specifically leads to the presence of zero divisors in sedenion algebra is definitely unique to my question. However, perhaps I should pose that as a separate question? Sorry, I'm not sure about that aspect of forum etiquette here. </p>

Are there existing extensions to behavior trees that fascilitate node communication?. <p>I've been looking into behavior trees, but I cannot find a lot about them. The Wikipedia page pretty much only mentions sequence and selector nodes.</p>
<p>I have found implementations that also provide memory selector, memory sequence, and parallel sequence, as well as some decorators like inversion and repetition.</p>
<p>I found some papers that discuss some form of a "weighted" selector/sequence that queries its children for their utility/probability. This can also be used in machine learning to dynamically adjust those weights.</p>
<p>What I have not yet found much about is communication between nodes.
Some implementations use a shared "blackboard" where nodes can write values, but this seems rather clumsy, as it creates a huge lookup table that tightly couples different nodes.</p>
<p>I've been thinking more in terms of sending messages to the next node.
I think the bulk of the shared state is a condition/action providing a specific value to the next action (rather than just success).</p>
<p>Has there been any research in this area? I was not able to find anything.
I'm also curious to hear about other useful extensions.</p>

<p>emerge. I wonder how Keras knows what of the data is part of the training and what is part of the testing? Though it's quite a basic question I'm not able to see the certain definition in the Keras documentation (the searching even does not provide any result there).
Therefore, I appreciate any help as I often cannot find any command definitions in <a href="http://faroit.com/keras-docs/1.2.0/search.html?q=load_data" rel="nofollow noreferrer">Keras</a>.

Homebrew asked me to move macports now it does not work. <p>I'm using HomeBrew for my usual mac stuff but I need to do some experiments with other package managers. So I installed MacPorts. everything seems alright but brew doctor asks me to move it:</p>
<blockquote>
<p>warning: You have MacPorts or Fink installed:</p>
<p>This can cause trouble. You don't have to uninstall them, but you may want to </p>
<p>temporarily move them out of the way, e.g. sudo mv /opt/local ~/macports</p>
</blockquote>
<p>So I listened and moved it. And then in my bash profile I changed </p>
<p><code>export PATH="/opt/local/bin:/opt/local/sbin:$PATH"</code></p>
<p>to </p>
<p><code>export PATH="~/macports/bin:~/macports/sbin:$PATH"</code></p>
<p>and now when I when run <code>port ...</code> it gives me this error:</p>
<blockquote>
<p>-bash: /Users/foobar/macports/bin/port: /opt/local/libexec/macports/bin/tclsh8.5: bad interpreter: No such file or directory</p>
</blockquote>
<p>What am I doing wrong and how can I solve it?</p>
<p><strong>P.S.1.</strong> </p>
<p>I edited the <code>/Users/foobar/macports/bin/port</code> file as the admin and edited the first line from
<code>#!/opt/local/libexec/macports/bin/tclsh8.5</code></p>
<p>to</p>
<p><code>#!/Users/foobar/macports/libexec/macports/bin/tclsh8.5</code></p>
<p>now I get this new error:</p>
<blockquote>
<p>sources_conf must be set in /opt/local/etc/macports/macports.conf or in your /Users/foobar/.macports/macports.conf file
while executing
"mportinit ui_options global_options global_variations"
Error: /Users/foobar/macports/bin/port: Failed to initialize MacPorts, sources_conf must be set in /opt/local/etc/macports/macports.conf or in your /Users/foobar/.macports/macports.conf file</p>
</blockquote>
<p><strong>P.S.2.</strong> </p>
<p>changed all the <code>/opt/local</code>s to <code>~/macports</code>s in </p>
<p><code>/Users/foobar/macports/var/macports/sources/rsync.macports.org/macports/release/tarballs/ports/_ci/bootstrap.sh</code> </p>
<p>and </p>
<p><code>/Users/foobar/macports/etc/macports/macports.conf</code></p>
<p>nothing changed!</p>
<p><strong>P.S.3.</strong></p>
<p>I see some of the guys here try to guid me towards removing/uninstalling MacPorts or HomeBrew. That's not what I'm asking for. I am able to revert all I did and make the MacPorts work again (in fact I just did that). My question is why HomeBrew Is saying that? what I happens If I don't do what it is asking for? What if I want the MacPorts too? and most importantly how make the MacPorts keep working after moving?</p>

Should I use a server to do multiple services. <p>I want to ask, I want to build a DNS server, mail server, and DHCP server and possibly an SQL server in my office, the client to this server is less than 100. So, if I have a server, say, with RAM 12 GB , and CPU 3GHz, should I cram all the roles in one server or should I use virtualization and separate the SQL server and the other server?</p>

Missing field in Apollo GraphQL Query. <p>I'm using react with Apollo and a F# backend. </p>
<p>When i make a query i get an error similar to this but i'm not sure why as it seems like stories is present in the response. </p>
<pre><code>Missing field stories in "{\"stories\":[{\"name\":\"Story1\",\"__typename\":\"Story\"},{\"name\":\"Story2\",\"__typename\":\
</code></pre>
<p>My code for making the query is: </p>
<pre class="lang-js prettyprint-override"><code>const client = new ApolloClient({
uri: '/graphql',
});
client
.query({
query: gql`
query testStoryQuery
{
stories
{
name
}
}
`
})
.then(result => console.log(result));
</code></pre>
<p>Finally the raw response returned by the server is:</p>
<pre><code>
{"data":"{\"stories\":[{\"name\":\"Story1\",\"__typename\":\"Story\"},{\"name\":\"Story2\",\"__typename\":\"Story\"},{\"name\":\"Story3\",\"__typename\":\"Story\"}]}"}
</code></pre>
<p>The only thing I've tried so far is jsonifying the response (i.e. the ") around fields, but it doesn't seem to find the field either way. </p>
<p>Update (extra info) </p>

I need a resource for self-studying c*algebras.. <p>I have just started my phd program this semester, I have not worked before on $C^*-$algebras, my master was on Geometry. In my university only reading courses are offered. I have to learn $C^*-$algebras. I have not taken any courses on functional analysis too. I am studying the book " $C^*-$algebras and their automorphism groups" by Pedersen, I usually google each topic and take a look at Book by Murphy too. But I could not find a good resource that give me a good prospective, for example how should I use Gelfand representation in problems. I mean I am learning topics, but I cannot learn with deep depth that I can use stuff like tools in my work. And Also I undestood that Functional analysis is a priority for $C^*-$algebras, but I cannot find a good book for understanding deeply materials like weak and weak$^*$ topology. When I read theorems I understand them, but I could not understand these topics as well as I give ideas for solving theorems on my own, and I cannot enjoy studying. I would appreciate if you recommend me some good books for self studying both Functional analysis and $C^*-$algebras.</p>

Something made me to turn back and I saw him quickly hiding the middle finger behind his back. I felt like my parent's prestige had been undermined. I told him if I see it again I would break his finger. Not the right choice of words, but it got me mad. What do I do in this situation? He wouldn't dare to flip me directly.

Win RT - universal app with barcode scanner. <p>I am developing a universal app for both Windows 8.1 and Windows Phone 8.1 which I want to be able to scan barcodes. For Windows 8.1, there exists a native class BarcodeScanner which is unfortunately inaccessible for Windows Phone 8.1 (I really don't understand what led Microsoft to do it this way). I found a 3rd party solution called zxing, but <a href="https://stackoverflow.com/questions/23472248/how-to-adjust-zxing-on-windows-phone-store-app-8-1-camera-mediacapture-preview">here</a> I have read that it works terribly for universal apps.

X.Org vs. XQuartz - MacPorts. <p>After installing MacPorts and some software through that way, I noticed that MacPorts installed X.Org.
I've already installed XQuartz years ago and I'm really fine with it.</p>
<p>My 1. question is:
Do I need the installed X.Org from MacPorts to run software like KeepNote or Gedit, which was installed automatically by MacPorts, or <strong>am I free to uninstall X.Org</strong> and leave XQuartz instead?</p>
<p>My 2. question is: What about the other way round? Keeping the automatically installed X.Org and remove XQuartz?</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:

Sphinx Autodoc vs. Coverage: Am I missing something here?. <p>I'm trying to use Sphinx to document a Python package which contains various sub-packages and sub-modules. I followed the stock Sphinx quickstart script which produced various files with <code>autodoc</code> directives that, in turn, with the <code>html</code> generator, produced a mostly-as-expected first-pass of the docs based on existing docstrings in the code. Cool.</p>
<p>Now enter <code>sphinx.ext.coverage</code>. With the project existing as it does after the "quickstart" script, running <code>sphinx-build -b coverage <other args></code> doesn't produce any meaningful output at all, just:</p>
<pre><code>Undocumented Python objects
===========================
</code></pre>
<p>...with nothing at all below it. I deliberately remove some docstrings to make sure, and sure enough, no warnings.</p>
<p>I thrashed around for a while and eventually tried using the non-<code>autodoc</code> directives, and lo and behold, <code>coverage</code> suddenly appears to work. Sadly, the <code>autodoc</code> functionality is a large part of what makes Sphinx appealing in the first place. But OK, putting in a <code>.. py:module::</code> directive for each of the modules helps; it appears to make the <code>coverage</code> extension aware of my modules, and from there I start to get entries in my <code>python.txt</code> about members within those modules that don't have docstrings. That's great, but it appears to mean that for <code>coverage</code> to report on a module, that module has to be explicitly, manually declared in the doc files, which kinda reduces the value of a <code>coverage</code> tool (i.e. if I add a new module to the package, it appears it won't be included in the coverage report until I specifically add a directive for it.) So, what I'm seeing is that <code>autodoc</code> seems capable of automatically traversing sub-modules/packages, but <code>coverage</code> does not. </p>
<p><strong>Question</strong>: Am I missing something? The inability to automatically discover new code appearing in a project seems like a pretty <strong>glaring fault</strong> for a "coverage" tool. It seems to me like a standard coverage tool ought to be opt-out, not opt-in.</p>
<p>As I pushed further, I found even yet more evidence that <code>coverage</code> and <code>autodoc</code> aren't friends. For instance, even when declaring modules manually with <code>.. py:module::</code> directives (as described above), I find that <code>coverage</code> is not picking up on things like <code>autodoc</code>'s <code>exclude-members</code> directive. This directive, as expected, elides matching members from the generated output when building HTML, but <code>coverage</code> still reports those members as undocumented in its coverage report. From my reading </p>
<p><strong>Question</strong>: Is this incompatibility between <code>coverage</code> and <code>autodoc</code> noted somewhere in the docs that I've not been able to find? Or, again, am I missing something?</p>

How can i use Raspberry PI to count how many times a switch is triggers on machines in a day?. What i need is a set of counting devices that count how many time the machines close/open in a day the machines already have a Switches on them, I've thought about the Raspberry PI to connect to this switch and then count how many times this switch is triggered, and then some way off viewing all the machines numbers in my office so i can see how the machines are running and whats not, and if possible views tables of how the machines have been running weekly/monthly to see what going on, on the factory floor i have about 32 machines on the factory floor. | 0non-cybersec

How to have overlapping under-braces and over-braces. <p>I am trying to typeset an equation that has overlapping over and under braces as per the image below:</p>
<p><img src="https://i.stack.imgur.com/DGtin.png" alt="enter image description here"></p>
<p>I have managed to typeset it using a sort of a hack, by typing the equation twice, once using <code>\phantom</code> commands and then raising it. Is there an easier way, perhaps a macro? MWE for the image above is shown below.</p>
<pre><code>\documentclass[12pt]{article}
\usepackage{amsmath}
\begin{document}
\[a+b+\overbrace{c+d+e+f+g}^{x}+h+i+k+l=e^2\]
\vspace{-35pt}
\[\phantom{+b+c+d+}\underbrace{\phantom{e+f+g+h+i}}_{y}\phantom{+k+=e^2}\]
\end{document}

Is there a pattern for subscribing to hierarchical property changes with Reactive UI?. <p>Suppose I have the following view models:</p>
<pre><code>public class AddressViewModel : ReactiveObject
{
private string line;
public string Line
{
get { return this.line; }
set { this.RaiseAndSetIfChanged(x => x.Line, ref this.line, value); }
}
}
public class EmployeeViewModel : ReactiveObject
{
private AddressViewModel address;
public AddressViewModel Address
{
get { return this.address; }
set { this.RaiseAndSetIfChanged(x => x.Address, ref this.address, value); }
}
}
</code></pre>
<p>Now suppose that in <code>EmployeeViewModel</code> I want to expose a property with the latest value of <code>Address.Line</code>:</p>
<pre><code>public EmployeeViewModel()
{
this.changes = this.ObservableForProperty(x => x.Address)
.Select(x => x.Value.Line)
.ToProperty(this, x => x.Changes);
}
private readonly ObservableAsPropertyHelper<string> changes;
public string Changes
{
get { return this.changes.Value; }
}
</code></pre>
<p>This will only tick when a change to the <code>Address</code> property is made, but not when a change to <code>Line</code> within <code>Address</code> occurs. If I instead do this:</p>
<pre><code>public EmployeeViewModel()
{
this.changes = this.Address.Changed
.Where(x => x.PropertyName == "Line")
.Select(x => this.Address.Line) // x.Value is null here, for some reason, so I use this.Address.Line instead
.ToProperty(this, x => x.Changes);
}
</code></pre>
<p>This will only tick when a change to <code>Line</code> within the current <code>AddressViewModel</code> occurs, but doesn't take into account setting a new <code>AddressViewModel</code> altogether (nor does it accommodate a <code>null</code> <code>Address</code>).</p>
<p>I'm trying to get my head around the correct approach to solving this problem. I'm new to RxUI so I could be missing something obvious. I <em>could</em> manually hook into address changes and set up a secondary subscription, but this seems ugly and error-prone.</p>
<p><strong>Is there a standard pattern or helper I should be using to achieve this?</strong></p>

}
}
public class EmployeeViewModel : ReactiveObject
{
private readonly ReactiveCommand changeAddressCommand;
private readonly ReactiveCommand changeAddressLineCommand;
private readonly ObservableAsPropertyHelper<string> changes;
private AddressViewModel address;
private int changeCount;
public EmployeeViewModel()
{
this.changeAddressCommand = new ReactiveCommand();
this.changeAddressLineCommand = new ReactiveCommand();
this.changeAddressCommand.Subscribe(x => this.Address = new AddressViewModel() { Line1 = "Line " + Interlocked.Increment(ref this.changeCount) });
this.changeAddressLineCommand.Subscribe(x => this.Address.Line1 = "Line " + Interlocked.Increment(ref this.changeCount));
this.Address = new AddressViewModel() { Line1 = "Default" };
// Address-only changes
this.changes = this.ObservableForProperty(x => x.Address)
.Select(x => x.Value.Line1 + " CHANGE")
.ToProperty(this, x => x.Changes);
// Address.Line1-only changes
//this.changes = this.Address.Changed
// .Where(x => x.PropertyName == "Line1")
// .Select(x => this.Address.Line1 + " CHANGE") // x.Value is null here, for some reason, so I use this.Address.Line1 instead
// .ToProperty(this, x => x.Changes);

An analysis problem about convergence. <p>Suppose that $f$ is a continuous function from $[a,b]$ to $[a,b]$. Let $x_0\in [a,b]$, and define by induction that $x_{n+1}=f(x_n)$. Show that $$\lim_{n \rightarrow \infty} (x_{n+1}-x_n)=0$$ implies $$\lim_{n \rightarrow \infty}x_n$$ exists.
（This problem is from a analysis book, and the author tells us the answer can be found in American Mathematical Monthly, volume 83(1976), page 273, which I have no access to, so you can either offer the reference or give the sketch of the proof. Thanks!）</p>

Travel Photography/VLOG: 18-135 stm & 50mm f1.8 vs Sigma 18-35 f1.8. Dear reddit,
I'm travelling soon and would like to add some lenses to my collection before travelling.
I have an 80D with me, as well as a 10-18mm wide angle lens.
However, this is not enough and i'm currently considering the lenses i mentioned in the title, namely:
18-135mm stm kit lens
50mm f1.8
vs
Sigma 18-35mm f1.8
Do you think the 18-135 & 50mm is a good combo along with my wide angle lens?
Or
Should I get the Sigma instead?
I'll be taking photos of my gf, taking vlogs, photos of scenery as well as timelapses.
Or do you have any recommendations?
Any help is greatly appreciated!
ps: budget is around £500
**EDIT: Thanks for all the replies, however, im at work now. I'll read them later when i get home! :)**

Algorithm for fast tag search. <p>The problem is the following.</p>
<ul>
<li>There's a set of simple entities E, each one having a set of tags T attached.
Each entity might have an arbitrary number of tags.
Total number of entities is near 100 million, and the total number of tags is about 5000.</li>
</ul>
<p>So the initial data is something like this:</p>
<pre><code>E1 - T1, T2, T3, ... Tn
E2 - T1, T5, T100, ... Tk
..
Ez - T10, T12, ... Tl
</code></pre>
<p>This initial data is quite rarely updated.</p>
<ul>
<li><p>Somehow my app generates a logical expression on tags like this:</p>
<p>T1&T2&T3 | (T5&!T6)</p></li>
<li><p>What I need to is to calculate a number of entities matching given expression (note - not the entities, but just the number). This one might be not totally accurate, of course. </p></li>
</ul>
<p>What I've got now is a simple in-memory table lookup, giving me a 5-10 seconds execution time on a single thread. </p>
<p>I'm curious, is there any efficient way to handle this stuff? What approach would you recommend? Is there some common algorithms or data structures for this?</p>
<p><strong>Update</strong></p>
<p>A bit of clarification as requested.</p>
<ol>
<li><code>T</code> objects are actually relatively short constant strings. But it doesn't actually matter - we can always assign some IDs and operate on integers.</li>
<li>We definitely can sort them.</li>
</ol>

Why is there an "age limit" on trick or treating?. I was listening to the radio this morning and lots of communities won't hand out candy to teenagers.
I feel like anyone, regardless of age should be able to trick or treat as long as they wear a costume. You are enganging with your community, neighbors, and people you normally wouldn't talk to. You have a fun time with friends dressing up, and if there wasn't a stigma that teenagers shouldn't trick or treat then they would be more likely to stay out of trouble.
I remember being 16-18 and dressing up with my friends and we all wanted to go trick or treat but felt emberrassed. We ended up driving around at night, running through yards, playing pranks, and smoking.
I recently started trick or treating with my brother and my niece, and we all dress up for her. It's really fun walking around and just exchanging a few words with neighbors, and checking out their costumes and decorations. | 0non-cybersec
