Which is better approach? : <p>I need to find subject, but it could be null. So have to do this without throwing exception. I have two approach and please suggest which is better?</p>
<pre><code>public static String getSafeSubject(SNSEvent.SNSRecord record){
try{
return record.getSNS().getSubject();
}catch (Exception e){
return "Failed to retrieve subject";
}
}
</code></pre>
<pre><code>public static String getSafeSubject(SNSEvent.SNSRecord record){
if(record == null || record.getSNS() == null ||
record.getSNS().getSubject() == null){
return "Failed to retrieve subject";
}
return record.getSNS().getSubject();
}

Python appends only one value : <p>Here is my Python Code</p>
<pre><code>pos = 0
for i in range(-10,10):
x = 3*i + 1
dataX = []
#dataX.append(x)
dataX.insert(pos,x)
print("insert "+str(x)+" at "+ str(pos) + "|" + str(dataX))
pos += 1
print(dataX)
</code></pre>
<p>Simply append should work right? but it does not, but so is insert..</p>
<p>Both returns same values as following..</p>
<pre><code>insert 1.9 at 13|[1.9]
</code></pre>
<p>that is 13th iteration as shown, and yet it does not do either insert nor append which should have generated list of data</p>
<p>I have no idea I've tried append as shown but results in [1.9] even with previous data.</p>

android app on kitkat works on lollipop don't : i'm asking to you some help beacause i can't find the solution.
i'm doing an android app and i have decided to add in my app the contact list.
i have take this from google android developpers
http://developer.android.com/training/contacts-provider/retrieve-names.html
and i have take the code and add all the features to my app(xml/layout/images/javacode etc)
and in my main activity i call the contactlist activity.
if i attack my cellular phone with kitkat 4.4.2 via debug on android studio my app comes and in mymain activity when i call the contacts activity it does so well...
but if i attack my cellular phone with lollipop 5.1.1 when i call the contacts activity it does so well the titlebar is hide and then when i click one contact the app crashes...
it crashes at this instruction
if (Utils.hasHoneycomb()) {
// Enables action bar "up" navigation
getActionBar().setDisplayHomeAsUpEnabled(true);
}
and it give to me

How to write output compiler in java? : <p>Is there a way to make a quine in java, then have some sort of program recognize the output as a program, then run that and give an output, and keep on doing so infinitely? I'm trying to write a self-replicating code and get it to infinitely reproduce itself, thereby technically creating life. I have a superiority complex, I suppose</p>

How to transform Future<List<Map> to List<Map> in Dart language? : <p>I have a question in coding with dart language. How to transform a Future to the normal List? In my program, I need the result from web to continue next step and I don't know how to do it.
In my case, I need to return the value of variable "data" as a List.</p>
<pre><code>class _MyAppState extends State<MyApp> {
static List getList() {
var url = "http://watcherman.cn/web/json.php";
var data;
HttpClient client = new HttpClient();
client.getUrl(Uri.parse(url))
.then((HttpClientRequest request) => request.close())
.then((HttpClientResponse response) {
response.transform(UTF8.decoder).listen((contents) {
String jsonContent = contents.toString();
data = JSON.decode(jsonContent);
});
});
return data;
}
}
</code></pre>
<p>But it seems like not execute the network part.
The flutter code part seems can't accept a Future.</p>
<pre><code>class _MyAppState extends State<MyApp> {
static List content = getList();
@override
Widget build(BuildContext context) {
return new Container(
child: new ListView.builder(
scrollDirection: Axis.vertical,

sqlalchemy classical mapping relationship issue : <p>I am on a mission to finally learn sqlAlchemy so that I can reap the benefits in the years to come. </p>
<p>I am neck deep in the sqlalchemy documents and have been for the past two days. I am hell bent on learning the classical mapping way, instead of the declarative, bc the db I want to hook up to exists, and does not have a unique id column in all of it's tables. <a href="http://www.blog.pythonlibrary.org/2010/09/10/sqlalchemy-connecting-to-pre-existing-databases/">According to this article classical mapping is the way to go under such circumstances</a></p>
<p>I have been following the classical examples from the sqlalchemy site, but I just cannot seem to find the correct relationship configuration to get this to work. </p>
<p>Here is all my code: </p>
<pre><code>engine = create_engine(
"mssql+pyodbc://someaddress/test?driver=FreeTDS?TDS_version=8.0", echo=True)
metadata = MetaData(engine)
class User(object):
def __repr__(self):
return "<User(User_id='%s', name='%s', age='%s')>" % (
self.user_id, self.name, self.age)
class Email(object):
def __repr__(self):
return "<User(email_id='%s', address='%s', user_id='%s')>" % (
self.email_id, self.address, self.user_id)
users = Table('users', metadata,
Column('user_id', Integer, primary_key=True),
Column('name', String(40)),
Column('age', Integer),
schema='test.dbo.users')
mapper(User, users, properties={'Email': relationship(Email, primaryjoin=users.c.user_id==emails.c.user_id)})
emails = Table('emails', metadata,
Column('email_id', Integer, primary_key=True),
Column('address', String),
Column('user_id', Integer, ForeignKey('test.dbo.users.user_id')),
schema='test.dbo.emails')
mapper(Email, emails)
Session = sessionmaker(bind=engine)
session = Session()
mary = session.query(User, Email).filter(User.user_id == Email.user_id)
</code></pre>
<p>The pursuing error message makes it clear that it is the mapper / relationship that is the problem.</p>
<pre><code>InvalidRequestError: One or more mappers failed to initialize - can't proceed with initialization of other mappers. Original exception was: Could not determine join condition between parent/child tables on relationship User.Email - there are no foreign keys linking these tables. Ensure that referencing columns are associated with a ForeignKey or ForeignKeyConstraint, or specify a 'primaryjoin' expression.
</code></pre>
<p>I have tried a long list of different things to try to remedy, but I just cannot get to the bottom of it. </p>
<p>Any pointers in the right direction would be much appreciated!</p>
<p>The sqlalchemy version I am on is; </p>
<pre><code>'1.0.12'

Access object from object within the object : <p>I try to program a small feed-forward neural network in oop java.
I have three different classes called layer, synapse and neuron.
One layer consists of a variable amount of nodes.
Each Synapse has a start and end-neuron and also a weight.
Now I want to access each weight attribute of the ingoing synapses from within the neurons. Somehow I can't wrap my mind around this.
Am I missing something?
I also tried working with a weighted graph, but I don't exactly know how to do it.</p>
<p>Thank you for helping!</p>

refactor function update model : My model: street_address, postal_code, latitude, longitude
Controller (update):
if @address.update(address_params)
postal_code = address_params[:address_attributes][:postal_code]
latitude, longitude = get_coordinate(postal_code)
@address.latitude = latitude
@address.longitude = longitude
@address.save
end
I want if the function get_coordinate can't get the coordinate the operation update will return false.
How can I refactor this piece of code ?

Firebase & Swift: How to use another database for storing larger files? : <p>I am currently trying to build a chat application in swift whilst using Firebase for real-time messaging. My only issue is I want users to send images, I want them to have profiles with images but I know Firebase has limited storage (or at least storage per pay tier is low for the number of connections you get)</p>
<p>So I would like to know how to connect up another database and make calls when needed between the two. So when and image is sent in a message, rather than Firebase storing the image, it stores a URL to the image in the other database.</p>
<p>I am under the impression something like AWS S3 is my best bet. any help is appreciated!</p>

How to writing a "if/unless" for an integer variable : I am trying to write a conditional where if a ends in 1 then it will answer with "st root" unless it ends with an 11 so it will be like 1st root or 11th root
(Then also work in similar ways for 2/12 and 3/13)
Here is the code I have tried
def n():
print("Only enter whole numbers\n ")
base = float(input("Enter number to take the root of, then hit enter:\n "))
input_string = input("Enter degree of roots (if more than one, separate by space) then hit enter:\n ")
list = input_string.split()
a = 1
for num in list:
base **= (1/float(num))
for num in list:
a *= int(num)
if str(a)[-1] == '1':
if str(a)[-1] != '11':
print(a,"st root",base)
elif str(a)[-1] == '2':
if str(a)[-1] != '12':
print(a,"nd root",base)
elif str(a)[-1] == '3':
if str(a)[-1] != '13':
print(a,"rd root",base)
else:
print(a,"th root",base)

<pre><code>docker pull docker.elastic.co/kibana/kibana:6.2.2

<p>Replacing pull with run it looks for the x-pack (I think it means not community) and fails to find the ES </p>

Collapsing CardView Animation not working correctly : <h2>What I'm trying to do</h2>
<p>I have a <code>RecyclerView</code> with many items that are basically some <code>CardView</code>.</p>
<p>Those cards have a supporting text in the middle of their bodies, which has the visibility set to <code>GONE</code> by default, and it's made <code>VISIBLE</code> when I click the arrow on the right of the card.</p>
<p>I'm trying to animate the card while the text is revealed and while it's collapsed.</p>
<p>The picture below shows the expanded card and the collapsed one:</p>
<p><a href="https://i.stack.imgur.com/KPexfl.png" rel="noreferrer"><img src="https://i.stack.imgur.com/KPexfl.png" alt="cards"></a></p>
<p>The <code>CardView</code> layout (I've removed some parts for readability):</p>
<pre><code><android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
card_view:cardCornerRadius="3dp"
card_view:cardElevation="4dp"
card_view:cardUseCompatPadding="true"
android:id="@+id/root">
<LinearLayout
android:id="@+id/item_ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="@dimen/activity_vertical_margin">
<!-- The header with the title and the item -->
<TextView
android:id="@+id/body_content"
style="@style/TextAppearance.AppCompat.Medium"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp"
android:layout_marginBottom="8dp"
android:text="@string/about_page_description"
android:textColor="@color/secondaryText"
android:visibility="gone"/>
<!-- The divider, and the footer with the timestamp -->
</LinearLayout>
</android.support.v7.widget.CardView>
</code></pre>
<h2>The problem</h2>
<p>The animations is working when the card is expanding and revealing the body <code>TextView</code>, however, when I try to collapse it back, the cards below the animated one overlaps the first one.</p>
<p><strong>Example:</strong></p>
<p><a href="https://i.stack.imgur.com/TCcc0.gif" rel="noreferrer"><img src="https://i.stack.imgur.com/TCcc0.gif" alt="card animation"></a></p>
<h2>What I've tried so far</h2>
<p>I've already asked a <a href="https://stackoverflow.com/questions/41982987/collapsing-cardview-inside-recyclerview-when-animating">similar question about this behavior here</a> before, but that solution is not working for a <code>TextView</code> in the middle of the card.</p>
<p>The code that's responsible for the animation part is inside the <code>RecyclerView</code> adapter. The arrow has a click listener that calls the method below:</p>
<pre><code>private fun toggleVisibility() {
if (bodyContent.visibility == View.GONE || bodyContent.visibility == View.INVISIBLE) {
btSeeMore.animate().rotation(180f).start()
TransitionManager.beginDelayedTransition(root, AutoTransition())
bodyContent.visibility = View.VISIBLE
}
else {
btSeeMore.animate().rotation(0f).start()
TransitionManager.beginDelayedTransition(root, AutoTransition())
bodyContent.visibility = View.GONE
}
}
</code></pre>
<p>Where <code>root</code> is my <code>CardView</code>.</p>
<p>I've also tried to use the <code>LinearLayout</code> instead of the card itself for the delayed transition, but that didn't work either.</p>
<p>How can I achieve that behavior for my layout?</p>

Why is visual studio code telling me that cout is not a member of std namespace? : <p>I am trying to setup visual studio code to program in c++. I have already installed the extensions <strong>C/C++</strong> and <strong>C/C++ Intellisense</strong></p>

Python 3.6: What is the different between these two list comprehension calculations? : So, I'm still relatively new to python, and mostly self-taught. I've been running my own statistical analyses, but I'm curious as to why there are different outputs for the following two list comprehensions. I am using Jupyter Notebook on Ubuntu LTS 16.04:
Input:
"example = [[15, 16, 17],
[18, 19, 20]]
list1 = [item[0] + item[1] + item[2] for item in example]
for item in example:
list2 = [item[0] + item[1] + item[2]]
list1, list2"
Output: ([48, 57], [57])
Clearly the second function is printing the sum of the second row, but why not the first?

Flutter slideTransition is not animating : <p>So I'm trying to create a trivial slide transition element in flutter and I'm having some difficulty. What the below does is wait for the animation time, and then just display the <code>Text("hello there sailor")</code>. I don't know why this is not animating - it seems very similar to this previous post that has a trivial example (<a href="https://stackoverflow.com/questions/53278792/sliding-animation-to-bottom-in-flutter?noredirect=1&lq=1">Sliding animation to bottom in flutter</a>).</p>
<p>This is how I call the below code: <code>DeleteCheck(offsetBool: widget.model.deleteNotify, widthSlide: 0.50*width100)</code> where <code>double width100 = MediaQuery.of(context).size.width;</code>.</p>
<p>Does anyone see what I am doing wrong?</p>
<pre><code>class DeleteCheck extends StatefulWidget{
final offsetBool;
final double widthSlide;
DeleteCheck({
Key key,
this.offsetBool,
this.widthSlide
}): super(key: key);
@override
State<StatefulWidget> createState() {
return new _MyDeleteCheck();
}
}
class _MyDeleteCheck extends State<DeleteCheck> with TickerProviderStateMixin {
AnimationController _controller;

_controller = AnimationController(
vsync: this,

_offsetFloat = Tween<Offset>(begin: Offset(widget.widthSlide, 0.0), end: Offset.zero)
.animate(_controller);
_offsetFloat.addListener((){

Passing data between a method and an event function : <p>Hello I have been struggling trying to get the event to trigger based on the object that it is passed.... I am not sure if that's how it should be worded but you guys can take a look at the book and give me some insight</p>
<p>I am making a datagrid form, inside this form, there's a function</p>
<pre><code>private void (List<string> listProducts>
{
foreach (aProduct in listProducts)
{
// reset row data
rowProduct = new string[10];
// add the row
this.dataDisplay.Tables["ProductData"].Rows.Add(rowProduct);
double checkingresult;
checkingresult = checkDiameter(aProduct);
}
</code></pre>
<p>Inside this form there's a function that would check the validity of the test product, so checkingresult would return 0 or 1</p>
<p>Then I created an event button to click on to change the color of the cell in the datagrid when it is clicked</p>
<pre><code>
private void bttnChecking_Click(object sender, EventArgs e)
{
DataGridViewCellStyle style = new DataGridViewCellStyle();
style.Font = new Font(datagridProductData.Font, FontStyle.Bold);
style.BackColor = Color.Red;
style.ForeColor = Color.White;
foreach (aProduct in ListProducts)
{
}
for (int i = 0; i < RowCount - 1; i++)
{
Rows[i].Cells[5].Style = style;
}
}
}
</code></pre>
<p>my question is, how do I pass the "checkingresult" into the event to change the color when it returns 0 or 1. Pls halp </p>

What is the point of the constants in redux? : <p>For example from this example:</p>
<pre><code>export const ADD_TODO = 'ADD_TODO'
export const DELETE_TODO = 'DELETE_TODO'
export const EDIT_TODO = 'EDIT_TODO'
export const COMPLETE_TODO = 'COMPLETE_TODO'
export const COMPLETE_ALL = 'COMPLETE_ALL'
export const CLEAR_COMPLETED = 'CLEAR_COMPLETED'
</code></pre>
<p>It's not like you're saving characters. The variable name is exactly the same as the string, and will never change. I understand making constants if one day you were doing to do something like:</p>
<pre><code>ADD_TODO = 'CREATE_TODO'
</code></pre>
<p>but that never happens. So what purpose do these constants serve?</p>

Compiling Code on Linux Server Seems to Run Differently : <p>I couldn't think of a good way to name this question, as the description of the issue is pretty lengthy. Basically, the issue I'm having is, code that I wrote in Xcode on my mac isn't running the same after I upload to a linux server for my school. I've never had this issue before. Its not a syntax issue, which is something that I might run into (IE maybe I dont need to include a certain header file on Xcode that needs to be included to run on the linux server, so I get an error when I try to compile there), but its a logic error. One specific if-else statement is evaluating entirely wrong. It works correctly in Xcode, but with the same .cc file uploaded to the linux server and compiled with a makefile, it has a totally different result, using the same exact input that was used in Xcode. I even open the .cc file with emacs after uploading to make sure none of the code has been altered from a botched upload, but nothing has changed at all. This is very strange. I've never ran into this sort of issue before. I'd like to provide the code, but it might be entirely too long, so I need to break it down into a smaller example. For now, I'd like to know if this is something anyone else has ever ran into. The assignment deals with graph theory. I'm typing in 'A' and 'B' to draw edges between two vertices. You can see it works from the Xcode build, but not from the Linux build.</p>

Python for loop - to iterate or not to iterate? : I'm writing a hangman game using Python, based on a specific set of instructions. I specifically need to use a for loop in order to replace all the letters in a word with underscores and in fact I am succeeding in doing so. However I have one slight issue, I'm getting a new line of underscores printed for every letter in my word. Is there a way to get rid of this? Can someone guide me on what is wrong with my logic? Thanks in advance.
word = "test"
def createBlank(word):
for letter in word:
blanks = '_' * len(word)
print(blanks)
My result is as you would assume:
>>> word
'test'
>>> createBlank(word)
____ #<- only need this line to be printed.. is it even possible using a for?

c# HastSet init takes too long : I'm dealing with the fact that I need to init a HashSet with a set of elements but without any kind of comparation class.
After the init, any element added to the HashSet need to be passed with a comparator.
How can I accomplish it?
Now I have this:
HashSet<Keyword> set = new HashSet<Keyword>(new KeyWordComparer());
The problem is that the init takes to long and there's no necessity in applying the comparation.

Pandas: split column of lists of unequal length into multiple columns : <p>I have a Pandas dataframe that looks like the below:</p>

4 [99213, 99287]

<p>I'm trying to split the lists in <code>df['codes']</code> into columns, like the below:</p>
<pre><code> code_1 code_2 code_3

2 77085
3 36415
4 99213 99287
5 99233 99233 99233
</code></pre>
<p>where columns that don't have a value (because the list was not that long) are filled with blanks or NaNs or something.</p>
<p>I've seen answers like <a href="https://stackoverflow.com/questions/35491274/pandas-split-column-of-lists-into-multiple-columns">this one</a> and others similar to it, and while they work on lists of equal length, they all throw errors when I try to use the methods on lists of unequal length. Is there a good way do to this?</p>

C - Inconsistent Data from Socket : <p>I've got a simple proxy server program written in C for a course. I'm having some issues with inconsistent data. When I request the website, I save the resulting data in a file on the server side, then send it over to the client and save it on the client side as well. The results on both the client and server will be of different sizes and it appears that some of the HTML is being duplicated. Typically, the file saved on the server will be smaller than the one saved on the client, although both files are still larger than the actual web page (i.e., if I were to right click the page and 'save as', the resulting page is smaller than those returned by my code). I've tried various things to resolve this issue and nothing seems to work. The results even seem to differ between attempts at the same website. For instance, I can request the same website twice, yet the file sizes differ from both attempts. In very rare occasions, especially on small websites, both the client and server program return the correct web page and both files are of the appropriate size.</p>
<p>Note: I'm aware that the code is still rather messy. I'm more worried about addressing this issue before I move any further. I will address issues (such as checking if the socket failed to open) once this issue is corrected, so please only address the issue I have outlined.</p>

C# Linking Array Properties : I have a class (Winforms application) that monitors status of a group of real-life switches, and stores their open/closed status in two arrays. One array is the status in binary (0,1) format, and the other in string ("open", "closed") format. The UI uses the string format, and internal calcs use both formats, so I need both arrays.
I keep banging my head trying to figure the best way to link those two arrays, so that if the app Sets one element of either array, the corresponding array element of the other gets set automatically at the same time, in the correct format.
I've considered using some sort of Binding, but apparently Winforms won't do binding between properties, only WPF. I've also considered using the Set of each property to have logic to set the other's element (see below), but I can't figure how to configure the Set to access individual array elements (indexer maybe, though I'm not sure if that's the right path since I know nothing about them).
Here's the code I have at the moment, and of course it doesn't work because it doesn't know how to equate the array with the int in the logic statement.
Any help with a solution would be greatly appreciated. Thanks.
public class SystemStatus
{
public string[] strStatus
{
get
{
return strStatus;
}
set
{
strStatus = value;
binStatus = value == "closed" ? 1 : 0;
}
}
public int[] binStatus
{
get
{
return binStatus;
}
set
{
binStatus = value;
strStatus = value == 1 ? "closed" : "open";
}
}

Dynamic classname inside ngClass in angular 2 : <p>I need to interpolate a value inside of an <code>ngClass</code> expression but I can't get it to work.</p>
<p>I tried these solution which are the only ones that makes sense to me, these two fails with the interpolation:</p>
<pre><code><button [ngClass]="{'{{namespace}}-mybutton': type === 'mybutton'}"></button>
<button [ngClass]="{namespace + '-mybutton': type === 'mybutton'}"></button>
</code></pre>
<p>This one works with the interpolation but fails with the dynamically added class because the entire string gets added as a class:</p>
<pre><code><button ngClass="{'{{namespace}}-mybutton': type === 'mybutton'}"></button>
</code></pre>
<p>So my question is how do you use dynamic classnames in <code>ngClass</code> like this?</p>

Difference between ! and % in Jupyter Notebooks : <p>Both <code>!</code> and <code>%</code> allow you to run shell commands from a Jupyter notebook.</p>
<p><code>%</code> is provided <a href="http://ipython.readthedocs.io/en/stable/interactive/magics.html" rel="noreferrer">by the IPython kernel</a> and allows you to run "magic commands", many of which include well-known shell commands. <code>!</code>, provided by Jupyter, allows shell commands to be run within cells. </p>
<p>I haven't been able to find <a href="https://www.dataquest.io/blog/jupyter-notebook-tips-tricks-shortcuts/" rel="noreferrer">much</a> comparing the two, and for simple shell commands like <code>cd</code>, etc. the main difference I see is that <code>%</code> is interactive and will actually change your location in the shell <em>while in the notebook</em>. </p>
<p>Are there other points or rules of contrast when thinking about which symbol to use for shell commands in a Jupyter Notebook?</p>

Kotlin - Void vs. Unit vs. Nothing : <p>Kotlin has three types that are very similar in nature:</p>
<ul>
<li><code>Void</code></li>
<li><code>Unit</code></li>
<li><code>Nothing</code></li>
</ul>
<p>It almost seems like they're making the JavaScript mistake:</p>
<ul>
<li><code>null</code></li>
<li><code>undefined</code></li>
<li><code>void(0)</code></li>
</ul>
<p>Assuming that they <em>haven't</em> fallen into the same mistake, what are they all for, and how do they differ?</p>
