34,929,206 | R Shiny selectInput that is dependent on another selectInput | <p>I have some data below that I'm using to create a donut chart in R shiny, where <code>date</code> is a character. I want to be able to select the email whose score I want to view, but then in the second dropdown selection only see the dates for which that email has activity.</p>
<p>For example, if I select email = xxxx in the first dropdown, I want to see only 'no activity' in the date selection field. And for email = yyyy, I want to see only 6/17/14, 6/18/14, 6/19/14 as selections. </p>
<p>I've tried a sort of nested subsetting in the ui. Example:</p>
<pre><code>> ui <- shinyUI(fluidPage(
+ sidebarLayout(
+ sidebarPanel(
+ selectInput('Select', 'Customer:', choices = unique(as.character(dat5$email))),
+ selectInput("User", "Date:", choices = dat5[dat5$email==input$Select,date])
+ ),
+ mainPanel(plotOutput("distPlot"))
+ )
+ ))
</code></pre>

<pre><code>email date variable value ymin ymax
xxxx no activity e_score 0 0 0
xxxx no activity diff 1 0 1
yyyy 6/17/14 e_score 0.7472 0 0.7472
yyyy 6/17/14 diff 0.2528 0.7472 1

34,931,121 | Can cond support TF ops with side effects? | <p>The (source code) documentation for <code>tf.cond</code> is unclear on whether the functions to be performed when the predicate is evaluated can have side effects or not. I've done some tests but I'm getting conflicting results. For example the code below does not work:</p>
<pre><code>import tensorflow as tf
from tensorflow.python.ops import control_flow_ops
pred = tf.placeholder(tf.bool, [])
count = tf.Variable(0)
adder = count.assign_add(1)
subtractor = count.assign_sub(2)
my_op = control_flow_ops.cond(pred, lambda: adder, lambda: subtractor)
sess = tf.InteractiveSession()
tf.initialize_all_variables().run()
my_op.eval(feed_dict={pred: True})
count.eval() # returns -1
my_op.eval(feed_dict={pred: False})
count.eval() # returns -2
</code></pre>
<p>I.e. no matter what value the predicate evaluates to, both functions are getting run, and so the net result is a subtraction of 1. On the other hand, this code snippet does work, where the only difference is that I add new ops to the graph every time <code>my_op</code> is called:</p>
<pre><code>pred = tf.placeholder(tf.bool, [])
count = tf.Variable(0)
my_op = control_flow_ops.cond(pred, lambda:count.assign_add(1), lambda:count.assign_sub(2))
sess = tf.InteractiveSession()
tf.initialize_all_variables().run()
my_op.eval(feed_dict={pred: False})
count.eval() # returns -2
my_op.eval(feed_dict={pred: True})
count.eval() # returns -1
</code></pre>
<p>Not sure why creating new ops every time works while the other case doesn't, but I'd obviously rather not be adding nodes as the graph will eventually become too big.</p>

34,932,734 | ESO Authentication on IIS for PHP and .NET applications (Shibboleth / SAML / WiF ...) | <p>I just wondered if you could answer a question regarding authentication in an enterprise's intranet. We are currently setting up a server for intranet publishing which of course needs protection via an enterprise single sign on.</p>
<p>Unfortunately we are stuck with an IIS server as we need to run both PHP and .NET applications. The main app is programmed in PHP, but we have to feature some jQuery included widgets that rely on ASPX handlers.</p>
<p>The company offers all types of authentication. We've already successfully protected the server with Shibboleth (using SAML 2.0). It shows the ESO screen to login and then redirects to our server with a logged-in session. Unfortunately the widgets that are referring to the ASPX handlers don't authenticate correctly.</p>
<p>I've never done authentication / SAML / WiF / anything, so please excuse my question:</p>
<p>What would be the most promising way for authentication with our setup (IIS featuren PHP and ASPX apps)? Should we stick to SAML and Shibboleth or should we use WiF / WS Federation / Windows Authentication?</p>
<p>Is it possible to support both PHP and ASPX with one authentication method?</p>

34,933,990 | Multi thread approach vs Akka actor model | <p>I'm new to akka actor. I have read the akka offical documents and still don't understand how actor works compare to threading model.</p>
<p>Let's take a simple example like this. I have a traditional HttpServer , which have 10 threads in the thread pools . When 20 requests are coming at the same time , the HttpServer will delegate all 10 threads in the thread pool to handle the first 10 requests and the others will be queued in the network interface to wait for the thread to pick up.</p>
<p>How will an actor-based HttpServer react to the same problem?. Will all of the requests are queued in front of a delegated actors to process them in a sequential order and send the messages to other actor?. If so, this is the point that I don't understand how can actor provide better performance than threading model, because only 1 actor process 20 requests in a sequential order can not faster than 10 thread process 20 requests concurrently.</p>
<p>What I am trying to understand is that how actor react when multiple requests are coming together at the same time? , not how actor process and queue the message in the mail box , it's already showed up a lot in the documents. Can someone simulate the steps how actor work in this example?</p>

<pre><code>||| This type is parameterised by:

||| + The input resource.
||| + The computation to run on the resource given the return value.
Effect : Type
Effect = (x : Type) -> Type -> (x -> Type) -> Type

<p>If we allow resources to be values and swap the first two arguments, we get (the rest of the code is in Agda)</p>
<pre><code>Effect : Set -> Set
Effect R = R -> (A : Set) -> (A -> R) -> Set
</code></pre>
<p>Having some basic type-context-membership machinery</p>
<pre><code>data Type : Set where
nat : Type
_⇒_ : Type -> Type -> Type
data Con : Set where
ε : Con
_▻_ : Con -> Type -> Con
data _∈_ σ : Con -> Set where
vz : ∀ {Γ} -> σ ∈ Γ ▻ σ
vs_ : ∀ {Γ τ} -> σ ∈ Γ -> σ ∈ Γ ▻ τ
</code></pre>
<p>we can encode lambda terms constructors as follows:</p>
<pre><code>app-arg : Bool -> Type -> Type -> Type
app-arg b σ τ = if b then σ ⇒ τ else σ
data TermE : Effect (Con × Type) where
Var : ∀ {Γ σ } -> σ ∈ Γ -> TermE (Γ , σ ) ⊥ λ()
Lam : ∀ {Γ σ τ} -> TermE (Γ , σ ⇒ τ ) ⊤ (λ _ -> Γ ▻ σ , τ )
App : ∀ {Γ σ τ} -> TermE (Γ , τ ) Bool (λ b -> Γ , app-arg b σ τ)
</code></pre>
<p>In <code>TermE i r i′</code> <code>i</code> is an output index (e.g. lambda abstractions (<code>Lam</code>) construct function types (<code>σ ⇒ τ</code>) (for ease of description I'll ignore that indices also contain contexts besides types)), <code>r</code> represents a number of inductive positions (<code>Var</code> doesn't (<code>⊥</code>) receive any <code>TermE</code>, <code>Lam</code> receives one (<code>⊤</code>), <code>App</code> receives two (<code>Bool</code>) — a function and its argument) and <code>i′</code> computes an index at each inductive position (e.g. the index at the first inductive position of <code>App</code> is <code>σ ⇒ τ</code> and the index at the second is <code>σ</code>, i.e. we can apply a function to a value only if the type of the first argument of the function equals the type of the value).</p>
<p>To construct a real lambda term we must tie the knot using something like a <a href="https://github.com/agda/agda-stdlib/blob/master/src/Data/W.agda" rel="noreferrer"><code>W</code></a> data type. Here is the definition:</p>
<pre><code>data Wer {R} (Ψ : Effect R) : Effect R where
call : ∀ {r A r′ B r′′} -> Ψ r A r′ -> (∀ x -> Wer Ψ (r′ x) B r′′) -> Wer Ψ r B r′′
</code></pre>
<p>It's the indexed variant of the Oleg Kiselyov's <a href="http://okmij.org/ftp/Haskell/extensible/more.pdf" rel="noreferrer"><code>Freer</code></a> monad (effects stuff again), but without <code>return</code>. Using this we can recover the usual constructors:</p>
<pre><code>_<∨>_ : ∀ {B : Bool -> Set} -> B true -> B false -> ∀ b -> B b
(x <∨> y) true = x
(x <∨> y) false = y
_⊢_ : Con -> Type -> Set
Γ ⊢ σ = Wer TermE (Γ , σ) ⊥ λ()
var : ∀ {Γ σ} -> σ ∈ Γ -> Γ ⊢ σ
var v = call (Var v) λ()
ƛ_ : ∀ {Γ σ τ} -> Γ ▻ σ ⊢ τ -> Γ ⊢ σ ⇒ τ
ƛ b = call Lam (const b)
_·_ : ∀ {Γ σ τ} -> Γ ⊢ σ ⇒ τ -> Γ ⊢ σ -> Γ ⊢ τ
f · x = call App (f <∨> x)
</code></pre>
<p>The whole encoding is very similar to the <a href="https://github.com/effectfully/DataData/blob/master/Container/Indexed.agda#L75" rel="noreferrer">corresponding encoding</a> in terms of <a href="http://strictlypositive.org/indexed-containers.pdf" rel="noreferrer">indexed containers</a>: <code>Effect</code> corresponds to <code>IContainer</code> and <code>Wer</code> corresponds to <code>ITree</code> (the type of Petersson-Synek Trees). However the above encoding looks simpler to me, because you don't need to think about things you have to put into shapes to be able to recover indices at inductive positions. Instead, you have everything in one place and the encoding process is really straightforward.</p>
<p>So what am I doing here? Is there some real relation to the indexed containers approach (besides the fact that this encoding has the same <a href="http://mazzo.li/epilogue/index.html%3Fp=324.html" rel="noreferrer">extensionality problems</a>)? Can we do something useful this way? One natural thought is to built an effectful lambda calculus as we can freely mix lambda terms with effects, since a lambda term is itself just an effect, but it's an external effect and we either need other effects to be external as well (which means that we can't say something like <code>tell (var vz)</code>, because <code>var vz</code> is not a value — it's a computation) or we need to somehow internalize this effect and the whole effects machinery (which means I don't know what).</p>

34,943,550 | Realm Swift Models separate or not? | <p>I'm new to the world of iOS and Swift and am working on a new app which I want to use Realm for persistence. I have Entities in my code already which my Services access and populate for an HTTP API endpoint. </p>
<p>Now I want to persist certain Entities and wanted advice as to whether I should create new Realm specific Models for each of my entities to read and write from Realm. Or should I convert all my existing plain Swift Entities to Realm Entities. At first this felt wrong as I would be passing Realm Entities al around my app instead of just in the persistence layer. </p>
<p>However, the alternative is that every time I read/write entities to Realm I need to convert them back and forth from Entities to Realm Entities. </p>
<p>Any advice on the best approach to this? </p>

I am trying to modify a pre-trained model and use it for other tasks. What I want is to speed up the training for new added layers and keep the trained layers at low learning rate in order to prevent them from being distorted. for example, I have a 5-conv-layer pre-trained model. Now I add a new conv layer and fine tune it. The first 5 layers would have learning rate of 0.00001 and the last one would have 0.001. Any idea how to achieve this?</p>

<p>There is a red border around the component, but nothing displays inside. I am new to React Native and new to StackOverflow. Unfortunately, they will not let me upload a screenshot until I have more reputation.</p>
<p>There is one line I suspect to be off, but have no idea what to change it to. Line #8 in RCTGoogleMapViewManager.h says, "@interface RCTGoogleMapViewManager : RCTViewManager". I have used UITextViewDelegates for other custom components, but this map is not a TextView. That might be it, but I have no clue.</p>
<p>Any help at all would be appreciated.</p>

34,951,812 | Why does -Xrs reduce performance | <p>From IBM:</p>
<blockquote>
<p><strong>-Xrs</strong></p>
<p>Disables signal handling in the JVM.</p>
<p><strong>-Xrs</strong></p>
<p>Setting -Xrs prevents the Java™ run time environment from handling any internally or externally generated signals such as SIGSEGV and SIGABRT. Any signals that are raised are handled by the default operating system handlers. <strong>Disabling signal handling in the JVM reduces performance by approximately 2-4%, depending on the application.</strong></p>
<p><strong>-Xrs:sync</strong></p>
<p>On UNIX systems, this option disables signal handling in the JVM for SIGSEGV, SIGFPE, SIGBUS, SIGILL, SIGTRAP, andSIGABRT signals. However, the JVM still handles the SIGQUIT and SIGTERM signals, among others. As with -Xrs, the use of <strong>-Xrs:sync reduces performance by approximately 2-4%, depending on the application.</strong></p>
<p><strong>Note:</strong> Setting this option prevents dumps being generated by the JVM for signals such as SIGSEGV and SIGABRT, because the JVM is no longer intercepting these signals.</p>
</blockquote>
<p><a href="https://www-01.ibm.com/support/knowledgecenter/SSYKE2_7.0.0/com.ibm.java.aix.70.doc/diag/appendixes/cmdline/Xrs.html">https://www-01.ibm.com/support/knowledgecenter/SSYKE2_7.0.0/com.ibm.java.aix.70.doc/diag/appendixes/cmdline/Xrs.html</a></p>
<p>From my understanding, <code>-Xrs</code> is really used to prevent dumps from being generated when certain OS Signals are intercepted.</p>
<p>Since the JVM is no longer intercepting and handling these signals, it would stand to reason this would <em>increase</em> performance, not <em>decrease</em> it as claimed by IBM.</p>

34,952,984 | React native flexbox - how to do percentages || columns || responsive || grid etc | <p>After working with react native on iOS for the last couple of weeks, I seem to have come across some shortcomings of flex styling... Particularly when it comes to "responsive" behavior. </p>
<p>For instance, lets say you want to create a view that contains cards (the metadata for these cards comes from an API). You want the cards to be 50% of the view width minus the margin & padding, and to wrap after each 2.</p>
<p><a href="https://i.stack.imgur.com/IKGF1.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/IKGF1.jpg" alt="enter image description here"></a></p>
<p>The current implementation I have for this view splits the returned array into rows with 2 items. The list container has <code>flex: 1, flexDirection: 'column</code>, the rows have <code>flex: 1</code> and then each card has <code>flex: 1</code>. The end result is each row has 2 columns which evenly take up half the view width. </p>
<p>It seems like there is no trivial way to do this in React Native styles, without using javascript to do some sort of pre-processing on the data so that it comes out styled correctly. Does anyone have any suggestions? </p>

<p>It's extremely easy to add a new object. All I have to do is something like </p>
<pre><code>return {

}
},

1: {

}
}

<p>Every approach I've thought of requires some complex object manipulation, which makes me feel like I'm not on the right track because normalizr is supposed to be making my life easier.</p>
<p>I can't find any examples online of someone working with the normalizr tree in this way. <a href="https://github.com/rackt/redux/tree/master/examples/real-world">The official example</a> does no adding and removing so it was no help either.</p>
<p>Could someone let me know how to add/remove from a normalizr tree the right way?</p>

Actually I'm using this code but it doesn't work, well the data pass from the child to the parent view but i can't see the result in the Progress Table, seems like i need to refresh but i also tryed the reloadData after the viewDidLoad and it doesn't work. Any suggestion? Thank you.</p>
