getting started with tensorflow | tensorflow : I am pretty new to tensorflow,and i am currently learning it through given website https://www.tensorflow.org/get_started/get_started
it is given that, "We've created a model, but we don't know how good it is yet. To evaluate the model on training data, we need a y placeholder to provide the desired values, and we need to write a loss function.
A loss function measures how far apart the current model is from the provided data. We'll use a standard loss model for linear regression, which sums the squares of the deltas between the current model and the provided data. linear_model - y creates a vector where each element is the corresponding example's error delta. We call tf.square to square that error. Then, we sum all the squared errors to create a single scalar that abstracts the error of all examples using tf.reduce_sum:"
Image of the above quote :https://i.stack.imgur.com/ztdpB.png
q1."we dont know how good it is yet.", i did'nt understand this quote as the simple model created is a simple slope equation and on what it should train for?, as the model is a simple slope. Is it require an perfect slope or what?
why am i training that model and for what?
q2.what is a loss function? Is loss function is used to determine the accuracy of the model? Why is it required?
q3. I did'nt understand " 'sums the squares of the deltas' between the current model and the provided data."
q4.I did'nt understood this part of code,"`squared_deltas = tf.square(linear_model - y)`
this is the code:
`y = tf.placeholder(tf.float32)
squared_deltas = tf.square(linear_model - y)
loss = tf.reduce_sum(squared_deltas)
print(sess.run(loss, {x:[1,2,3,4], y:[0,-1,-2,-3]}))`
this may be simple questions, but i am a beginner to tensorflow and having a hard time understanding it. Could any one please help me out, thanks :) | 0debug |

How to .catch a Promise.reject : <p>I have a helper function for using <code>fetch</code> with CouchDB which ends as:</p>

.then(do_something)
.catch(err => do_something_with_the_json_error_rejection_or_resp_not_ok_rejection_or_the_above(err))

Cannot build APK - DexExcepction : When I'm building my project by "Run (applicaton)" build-in function - everything's fine, I can test my app through phone, but I want to create standalone application by gradle.
I'm using **gradle :client:clean :client:assemble** task, and that's my output:
Dex: Error converting bytecode to dex:sesWithDexForDebug
Cause: com.android.dex.DexException: Multiple dex files define Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;
UNEXPECTED TOP-LEVEL EXCEPTION:

By [this link][1] I've searched for some dependencies between my modules. I checked, that appcompat-v7 and design library have support-v4 library build-in, so I removed it from design library.
My **build.gradle** file:

make pip ignore an existing wheel : <p>If a <code>.whl</code> is available online, <code>pip</code> always installs it rather than compiling from source. However, for some specific module, the wheel happened to be compiled for the next processor generation and doesn't run on a specific machine.</p>
<p>If I command it to just download the package, then it still downloads the wheel rather than source. Does <code>pip</code> have some mechanism to override this preference?</p>

Horizontal RecyclerView with items that have dynamic height : <p>So I need a horizontal RecyclerView. However the items in them have dynamic height based on what's returned from the backend.</p>
<p>The RecyclerView and its items have height of "wrap_content"</p>
<p>The problem is if the first visible items in the RecyclerView are small, then when the user scrolls to the larger items, they appear cut off.</p>
<p>Ideally we want the RecyclerView to be large enough to hold the largest item in the group (but only the largest existing item... not the hypothetically largest item). The RecyclerView dynamically changing its height is also acceptable.</p>
<p>I wrote an example app to illustrate the problem. In this app, we have a horizontal list. The first 33 items should show 1 line of text, while the next should show 3 lines of text, and the last 34 should show 2 lines. However, they all show 1 line, because the height of the RecyclerView doesn't change.</p>
<p>I've tried calling requestLayout() on the RecyclerView (and on the TextView) from onBindViewHolder(), but it doesn't seem to do anything.</p>

<pre><code>public class MainActivity extends AppCompatActivity {

concurrent map read and write when there is no concurrency : <p>The following go play example shows in a simplistic way what I have defined.

Can scoped_lock lock a shared_mutex in read mode? : <p>C++17 introduced both <code>std::shared_mutex</code> and <code>std::scoped_lock</code>. My problem is now, that it seems, that <code>scoped_lock</code> will lock a shared mutex always in exclusive (writer) mode, when it is passed as an argument, and not in shared (reader) mode. In my app, I need to update an object <code>dst</code> with data from an object <code>src</code>. I want to lock <code>src</code> shared and <code>dst</code> exclusive. Unfortunately, this has the potential for deadlock, if a call to another update method with <code>src</code> and <code>dst</code> switched occurs at the same time. So I would like to use the fancy deadlock avoidance mechanisms of <code>std::scoped_lock</code>.</p>
<p>I could use <code>scoped_lock</code> to lock both <code>src</code> and <code>dst</code> in exclusive mode, but that unnecessarily strict lock has performance backdraws elsewhere. However, it seems, that it is possible to wrap <code>src</code>'s <code>shared_mutex</code> into a <code>std::shared_lock</code> and use that with the <code>scoped_lock</code>: When the <code>scoped_lock</code> during its locking action calls <code>try_lock()</code> on the <code>shared_lock</code>, the later will actually call <code>try_shared_lock()</code> on <code>src</code>'s <code>shared_mutex</code>, and that's what I need.</p>
<p>So my code looks as simple as this:</p>
<pre><code>struct data {
mutable std::shared_mutex mutex;
// actual data follows
};
void update(const data& src, data& dst)
{
std::shared_lock slock(src.mutex, std::defer_lock);
std::scoped_lock lockall(slock, dst.mutex);
// now can safely update dst with src???
}
</code></pre>
<p>Is it safe to use a (shared) lock guard like this inside another (deadlock avoidance) lock guard?</p>

PaaS Offerings for Node.js : <p>I keep finding blogs and articles that list Digital Ocean and Linode as having PaaS offerings for Node.js. This is bothering me because I've hosted apps on both Linode and Digital Ocean and although they do have one-click installs of Node.js or MongoDB stacks, You are still responsible as a developer for securing your infrastructure, managing it, upgrading it, etc.</p>
<p><a href="https://modulus.io/nodejs" rel="nofollow noreferrer">Modulus</a> is something i've been looking at that seems to be a truly PaaS platform for Node.js.</p>
<p>Am i misunderstanding the definition of PaaS or are all these blogs/articles talking about Digital Ocean and Linode having PaaS offerings for Node.js actually incorrect?</p>

Overwrite wordpress css? : <p>So i am currently creating a website for a eSports team in wordpress, and i have just ran into a problem, that i do not remember how to sort out. I remember from making chrome extensions there is a method for doing this, but i do not remember, and that is why i am here now :)</p>
<p><a href="https://i.stack.imgur.com/0nLYB.png" rel="nofollow noreferrer">First code</a>
As you can see on the picture, that is what is in the CSS, and i need to keep that for other pages, but i want my one page to overwrite that. I have a box where i am allowed to add custom CSS, but when i add the code, it gets overwritten by the old code. I know why this happends, but not how to fix it without changing the original css (which i would prefer to avoid)</p>
<p><a href="https://i.gyazo.com/823cdc79449f2bb2905eab8a1828f338.png" rel="nofollow noreferrer">Overwritten code</a></p>
<p>So my question is, how to i make my new css overwrite my old css?
(i have tried !important and it does nothing)</p>

Programming language to write logic for microsoft sql server : I've been using microsoft sql server to write queries. I was browsing online and i found that python and c# can be used to write query logic as well. I was wondering is it more efficient to use another programming language instead of SQL for microsoft sql server? | 0debug |

Why you would choose ASP.NET MVC over SPA + ASP.NET WebAPI? : <p>I'm asking this just to see experiences from others.
For most of the cases having ASP MVC web site is an overhead. At least for me it's much cleaner and easier to have WebAPI which responds with JSON and then you can attach either SPA application or Mobile app or whatever.</p>
<p>I have a feeling that if you are using ASP MVC controllers will not be controllers, but controllers full of the if conditions and some session bags which are hanging around. Views are combination of HTML and Razor which in most cases looks really ugly and full of "TODOs" ;) </p>
<p>I can understand if it's used in older projects and now we just need to maintain them. But when you are starting a new one, why you would choose ASP.NET MVC or any other similar framework?</p>

Which algorithm should I use for this ? Can someone please give an example for this.</p>

how to prioritize a variable (Python) : Okay so I have been having a problem making a variable prioritized without anything to do with length. I want D to be prioritized because it his the highest variable then after I want it to prioritize C so on and so on, until it reaches 80
I've only seen example so far about using max() which is not what I need
a = 60
b = 30
c = 50
d = 20
so i want it to select the 20 D then the 50 C then 10 B | 0debug |

Good way to chain filter functions in javascript : <p>I've got large json array of objects that I need to filter down based on multiple user select inputs. Currently I'm chaining filter functions together but I've got a feeling this is most likely not the most performant way to do this.</p>
<p>Currently I'm doing this:</p>
<pre><code>var filtered = data.filter(function(data) {
return Conditional1
})
.filter(function(data) {
return Conditional2
})
.filter(function(data) {
return Conditional3
}) etc...;
</code></pre>
<p>Although (I think) with each iteration 'data' could be less, I'm wondering if a better practice would be to do something like this:</p>
<pre><code>var condition1 = Conditional1
var condition2 = Conditional2
var condition3 = Conditional3
etc...
var filtered = data.filter(function(data) {
return condition1 && condition2 && condition3 && etc...
});
</code></pre>
<p>I've looked into multiple chains of higher order functions, specifically the filter function - but I haven't seen anything on best practice (or bad practice, nor have I timed and compared the two I've suggested).</p>
<p>In a use case with a large data set and many conditionals which would be preferred (I reckon they are both fairly easily readable)?</p>
<p>Or maybe there is a more performant way that I'm missing (but still using higher-order functions).</p>

<p>by means of non printable, i mean delete all characters that are not shown in ie output, when one prints the input string. Please note, i look for a c# regex, i do not have a problem with my code</p>

How to gracefully handle exceptions in Spring Security not handled by ControllerAdvice? : <p>I have recently implemented Spring Security in my Spring 4 / Hibernate Web application to handle logging in/out and different user roles. </p>
<p>After a lot of reading it appears to work pretty fine now, but I noticed that exceptions thrown due to a wrong Spring Security configuration were not handled gracefully using my custom handler but shown as an ugly Tomcat error page (showing HTTP Status 500 - UserDetailsService is required followed by a stacktrace). </p>
<p>Solving the particular error was not difficult (adding userDetailsService(userDetailsService) in the RememberMe configuration) but the fact remains that some exceptions thrown are not handled by the
ControllerAdvice shown below handling MaxUploadSizeExceededException and all other runtime exceptions:</p>
<pre><code>@ControllerAdvice
public class ExceptionHandlingControllerAdvice {
public static final String DEFAULT_ERROR_VIEW = "genericerror";
@ExceptionHandler(value = MaxUploadSizeExceededException.class)
public View maxUploadSizeExceededExceptionHandler(
HttpServletRequest req) throws IOException {
String redirectUrl = req.getRequestURL().toString();
RedirectView rv = new RedirectView(redirectUrl);
FlashMap outputFlashMap = RequestContextUtils.getOutputFlashMap(req);
if (outputFlashMap != null) {
outputFlashMap.put(KeyConstants.FLASH_ERROR_KEY, "Bestand is te groot");
}
return rv;
}
@ExceptionHandler(value = RuntimeException.class)
public View defaultErrorHandler(HttpServletRequest req, Exception e) {
RedirectView rv = new RedirectView("/error", true); //context relative
StackTraceElement[] steArray = e.getStackTrace();
StringBuilder stackTrace = new StringBuilder();
for (StackTraceElement element: steArray) {
stackTrace.append(element.toString() + "\n");
}
FlashMap outputFlashMap = RequestContextUtils.getOutputFlashMap(req);
if (outputFlashMap != null) {
outputFlashMap.put("url", req.getRequestURL());
outputFlashMap.put("excClassName", e.getClass().getName());
outputFlashMap.put("excMessage", e.getMessage());
outputFlashMap.put("excStacktrace", stackTrace.toString());
}
e.printStackTrace();
return rv;
}
}
</code></pre>
<p>But the exception thrown by the incomplete configured Security is probably not caught by this mechanism because the login POST request is intercepted by Spring Security before any controller method is called. I would like to show ALL exceptions in graceful way on a custom error page, also the ones thrown before a Controller comes into place.</p>
<p>I cannot find much information about that, all error handling techniques described in the Spring manual (<a href="http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-exceptionhandlers" rel="noreferrer">http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#mvc-exceptionhandlers</a>) seems to use a Controller advice. </p>
<p>Is there a convenient way to handle ALL exceptions in a generic way? And makes that my Controller advice class to handle exceptions superfluous?</p>

Difference between new Observable(...) and Rx.Observable.create(...)? : <p>I'm updating our software substituting all promises (and other hairy junk) for observables. To make sure that I'm following best practices, I made a quick googlearch and noticed that in <a href="https://angular-2-training-book.rangle.io/handout/observables/error_handling.html" rel="noreferrer">some cases</a>, the suggested syntax is by instance whereas in <a href="https://xgrommx.github.io/rx-book/content/getting_started_with_rxjs/creating_and_querying_observable_sequences/creating_and_subscribing_to_simple_observable_sequences.html" rel="noreferrer">other cases</a>, the examples perform a call by factory. </p>
<pre><code>const byInstance = new Observable(_ => { ... });
const byFactory = Rx.Observable.create(_ => { ... });
</code></pre>
<p>I'm curious what's the actual difference. Are they precisely interchangeable? Is it an older/newer syntax/approach? Is it framework related? And, of course, which is to be preferred (<strong>under the condition that</strong> it's not opinionated, disputed etc.).</p>
