Firebase: Query to exclude data based on a condition | <p>I'm able to get the data for a particular value in the child using <code>orderByChild</code> and <code>equalTo</code> (cool that it works for nested child as well) </p>
<pre><code>private void getData() {
try {
final DatabaseReference database = FirebaseDatabase.getInstance().getReference();
database.child(Constants.TABLE_TASKS).orderByChild("user/id")
.equalTo("somevalue")
.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
Timber.d(dataSnapshot.toString());
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
} catch (Exception ex) {
ex.printStackTrace();
}
}
</code></pre>
<p>Is there an easy way to get the data where a particular value is not found, basically something like a <code>notEqualTo("somevalue")</code> ? </p> | 0 |

How to create nested object in MongoDB schema | <p>I currently have the following schema for a MongoDB document which is supposed to save user data:</p>
<pre><code>var userSchema = new mongoose.Schema({
username: {type: String, unique : true},
password: {type: String},
firstname: String,
lastname: String,
sketches:
[
{name: String,
sketch: Array}
]
</code></pre>
<p>The sketches attribute needs to be an array objects where each object associates the name of a sketch and an array which holds the sketch data. For some reason, the schema ends up being created as the following:</p>
<pre><code>{
"__v" : 1,
"_id" : ObjectId("57c4d7693aa85cea2acf4d4d"),
"firstname" : "test",
"lastname" : "name",
"password" : "password123",
"sketches" : [
{
"sketch" : []
}
],
"username" : "testname"
}
</code></pre>
<p>I'm not exactly sure the correct format for creating nested objects in MongoDB but I was assuming that it would be the same as it would for JSON. How should the schema be structured to yield an array of objects.</p>

Set and get using tag a fragment in android | <p>I've created a tab layout with viewpager.
Everything was alright, except that I need to run a method in a specific moment. So I need to get fragment instance and run their method.
I create in this way:</p>
<pre><code>@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
activateToolbarWithNavigationView(HomeActivity.this);
// Tabs Setup
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
final ViewPager viewPager = (ViewPager) findViewById(R.id.home_pager);
if (tabLayout != null) {
tabLayout.addTab(tabLayout.newTab().setText(getString(R.string.favorites_label_fragment)).setTag(getString(R.string.fragment_favorite_tag)));
tabLayout.addTab(tabLayout.newTab().setText(getString(R.string.air_today_label_fragment)).setTag(getString(R.string.fragment_airing_today_tag)));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final HomePageAdapter adapter = new HomePageAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
if (viewPager != null) {
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
}
public void refreshFavorites(){
FavoritesFragment favoritesFragment = (FavoritesFragment) getSupportFragmentManager().findFragmentByTag(getString(R.string.fragment_favorite_tag));
if(favoritesFragment != null) favoritesFragment.executeFavoriteList();
}
</code></pre>
<p>I don't know if i'm doing it in wrong way, or there some mistake that they return null from findFragmentByTag... I can't figure out. In case, I've checked some others answers but I can't understand what I really need to do.</p>
<p>viewpager adapter:</p>
<pre><code>public class HomePageAdapter extends FragmentStatePagerAdapter {
int mNumOfTabs;
public HomePageAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
FavoritesFragment favoritesFragment = new FavoritesFragment();
return favoritesFragment;
case 1:
AirTodayFragment airTodayFragment = new AirTodayFragment();
return airTodayFragment;
default:
return null;
}
}
@Override
public int getCount() {
return mNumOfTabs;
}

for (Fragment fragmento: allFragments) {
if (fragmento instanceof FavoritesFragment){
((FavoritesFragment) fragmento).executeFavoriteList();
}
}
}
</code></pre>
<p><strong>EDIT 2: WHERE I USE:</strong></p>
<p>I didn't use refreshFavoretes inside my Activity but actually in Fragments that are inside of it:</p>
<pre class="lang-cs prettyprint-override"><code>@Override
public void onClick(View v) {
...
// Refresh Favorites
if (getActivity() instanceof MainActivity) ((MainActivity) getActivity()).refreshFavorites();
}

Getting list of class fields | <p>I am trying to create a generic method for my search, but I don't know how to return list of fields from my class.</p>
<p>Let's say I've got a class: </p>
<pre><code>public class Table
{
[Key]
public int ID { get; set; }
public string Name { get; set; }
public string Address { get; set; }
}
</code></pre>
<p>And now I want to return a list that would look like this:</p>
<pre><code>"ID"
"Name"
"Address"
</code></pre>
<p>How do I do that?</p>
<p>tried something like this:</p>
<pre><code> FieldInfo[] fields = typeof(T).GetFields(
BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
string[] names = Array.ConvertAll<FieldInfo, string>(fields,
delegate(FieldInfo field) { return field.Name; });
</code></pre>
<p>But it has some unnecessary text after field names</p>
<h2><strong>EDIT</strong></h2>
<p>It's not duplicate because in my situation GetProperties()<strong>.Select(f => f.Name)</strong> made a difference</p> | 0 |

“href” value in HTML to open video in youtube app or market (Google Play) on Android | <p>I'm making a Web Page that shows 360 videos, but i recently noticed that 360 functionality in the android browser is not supported, and because of this the video wont shows correctly, so after searching a lot i found that the best option is to try to open the video in the YouTube app making use of an "Android Intent" explained in this developer tutorial:</p>

<pre><code>intent:
HOST/URI-path <-- I think here needs to be the video URL?
#Intent;
package=com.google.android.youtube.player.YouTubeIntents; <-- Is this the correct package? or should i use com.google.android.youtube.player?
action=createPlayVideoIntentWithOptions(context, UUweNrpFTwA, true, true); <-- Dont know what to put in context field
category=[string]; <-- Is category needed? if so what category should i place here?
component=[string]; <-- Is component needed?
scheme=youtube; <-- Is this the correct scheme?
end;

Play multiple sounds at the same time in python | <p>I have been looking into a way to play sounds from a list of samples, and I found some modules that can do this.</p>

sound = Somelist
with AudioIO(True) as player:
player.play(sound, rate=44100)

Alexa Skill not recognized when tested on Echo | <p>I was doing one of the tutorials (HelloWorld) to make a skill for the Echo and I followed the directions. When I tested the skill using the Service Simulator, I typed in </p>
<pre><code>Alexa, tell Greeter to say hello
</code></pre>
<p>and that returned the following JSON response:</p>
<pre><code>{
"version": "1.0",
"response": {
"outputSpeech": {
"type": "PlainText",
"text": "Hello World!"
},
"card": {
"content": "Hello World!",
"title": "Greeter",
"type": "Simple"
},
"shouldEndSession": true
},
"sessionAttributes": {}
}
</code></pre>
<p>I think that is the correct output. However, when I tried testing the skill on my Echo, Alexa replies "Sorry, I didn't your question." I went on the history and Alexa interpreted my command as "alexa tell greeter to say hello." It seems that Alexa is not recognizing the skill? </p>
<p>I am using Amazon Lambda to execute the code, so I checked the logs and the code was not executed when I spoke the command to above. </p>
<p>I replaced the app_id in the javascript file to the one that corresponds to my skill. I have also put the amazon skills kit as a trigger. </p>
<p>I also tried the other tutorials (ChemistryFlashCards and HistoryBuff), and Alexa replies "I'm not sure what you meant by that." </p>
<p>Not sure what is happening! Any guidance is appreciated!!</p> | 0 |

How to POST a DateTime value to a Web API 2 controller | <p>I have an example controller:</p>
<pre><code>[RoutePrefix("api/Example")]
public class ExampleController : ApiController
{
[Route("Foo")]
[HttpGet]
public string Foo([FromUri] string startDate)
{
return "This is working";
}
[Route("Bar")]
[HttpPost]
public string Bar([FromBody] DateTime startDate)
{
return "This is not working";
}
}
</code></pre>
<p>When I issue a GET request to: <code>http://localhost:53456/api/Example/Foo?startDate=2016-01-01</code> it works.</p>
<p>When I POST to <code>http://localhost:53456/api/Example/Bar</code> I receive a <code>HTTP/1.1 400 Bad Request</code> error.</p>
<p>This is my POST data:</p>
<pre><code>{

Getting 'dict_keys' object does not support indexing despite casting to list | <p>I am using Python 3 and despite of casting to list, I cannot seem to run my program.</p>
<p>This is the function calling:</p>
<pre><code>path = euleriancycle(edges)
</code></pre>
<p>And this is where I have used the keys method:</p>
<pre><code>def euleriancycle(e):
currentnode = list[e.keys()[0]]
path = [currentnode]
</code></pre>
<p>I tried to run it without type-casting to list and got this error. After rummaging about this site and similar queries, I followed the solutions suggested and type-cast to list but to no avail. I got the same error. </p>
<p>This is the error track:</p>
<pre><code>---------------------------------------------------------------------------

Update multiple records using stored procedure | <p>Being a novice, I had a question that is helping me troubleshoot something I'm working on.</p>
<p>With the table created below, is there a way to modify the stored procedure to update multiple rows in the table</p>
<pre><code>CREATE TABLE AccountTable
(
RowID int IDENTITY(1, 1),
AccountID varchar(2),
AccountName varchar(50),
SeqNum int,
SeqDate datetime
)
CREATE PROCEDURE [ACCOUNTTABLE_UPDATE]
(
@SeqNum int,
@SeqDate datetime,
@Account_ID varchar(2)
)
AS
SET NOCOUNT ON
BEGIN
UPDATE AccountTable
SET SeqNum = @SeqNum, SeqDate = @SeqDate
WHERE AccountID = @AccountID
END
EXEC ACCOUNTTABLE_UPDATE SeqNumValue, SeqDateValue, AccountIDValue
</code></pre>
<p>Running the stored procedure manually will of course edit one row, adding more values will lead to a too many arguments error. I just wanted to see if this stored procedure can in fact update more than one row in the table or if this should be modified to in fact handle providing more than the 3 parameters.</p> | 0 |
PostgreSQL slow JOIN with CASE statement | <p>In my database I have a table that contains ~3500 records and as a part of more complicated query I've tried to perform inner join on itself using "CASE" condition just as you can see below.</p>
<pre><code>SELECT *
FROM some_table AS t1
JOIN some_table AS t2 ON t1.type = t2.type
AND CASE
WHEN t1.type = 'ab' THEN t1.first = t2.first
WHEN t1.type = 'cd' THEN t1.second = t2.second
-- Column type contains only one of 2 possible varchar values
END;
</code></pre>
<p>The problem is this query is performed for 3.2 - 4.5 seconds while next request is performed in 40 - 50 milliseconds.</p>
<pre><code>SELECT *
FROM some_table AS t1
JOIN some_table AS t2 ON t1.type = t2.type
AND (t1.first = t2.first OR t1.second = t2.second)
</code></pre>
<p>Also according to the execution plan in first case database processes ~5.8 millions of records while table contains only ~3500. There are next indexes on this table: (id), (type), (type, first), (type, second). </p>
<p>We are using next version:
PostgreSQL 9.4.5 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120
313 (Red Hat 4.4.7-16), 64-bit</p>
<p>Any ideas why PostgreSQL works so weird in this case?</p> | 0 |
how to remove last comma from line in bash using "sed or awk" | <p>Hi I want to remove last comma from a line. For example:</p>
<p>Input:</p>
<pre><code>This,is,a,test
</code></pre>
<p>Desired Output:</p>
<pre><code>This,is,a test
</code></pre>
<p>I am able to remove last comma if its also the last character of the string using below command: (However this is not I want)</p>
<pre><code>echo "This,is,a,test," |sed 's/,$//'
This,is,a,test
</code></pre>
<p>Same command does not work if there are more characters past last comma in line.</p>
<pre><code>echo "This,is,a,test" |sed 's/,$//'
This,is,a,test
</code></pre>
<p>I am able to achieve the results using dirty way by calling multiple commands, any alternative to achieve the same using awk or sed regex ?(This is I want)</p>
<pre><code>echo "This,is,a,test" |rev |sed 's/,/ /' |rev
This,is,a test

Converting time from AM/PM format to military time in Python | <p>Without using any libraries, I'm trying to solve the Hackerrank problem "<a href="https://www.hackerrank.com/challenges/time-conversion?h_r=next-challenge&h_v=zen" rel="noreferrer">Time Conversion</a>", the problem statement of which is copied below.</p>
<p><a href="https://i.stack.imgur.com/YRr6p.png" rel="noreferrer"><img src="https://i.stack.imgur.com/YRr6p.png" alt="enter image description here"></a></p>
<p>I came up with the following:</p>
<pre><code>time = raw_input().strip()
meridian = time[-2:] # "AM" or "PM"
time_without_meridian = time[:-2]
hour = int(time[:2])
if meridian == "AM":
hour = (hour+1) % 12 - 1
print ("%02d" % hour) + time_without_meridian[2:]
elif meridian == "PM":
hour += 12
print str(hour) + time_without_meridian[2:]
</code></pre>
<p>However, this fails on one test case:</p>
<p><a href="https://i.stack.imgur.com/yQLb9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/yQLb9.png" alt="enter image description here"></a></p>
<p>Since the test cases are hidden to the user, however, I'm struggling to see where the problem is occurring. "12:00:00AM" is correctly converted to "00:00:00", and "01:00:00AM" to "01:00:00" (with the padded zero). What could be wrong with this implementation?</p> | 0 |

RGB to HSL conversion | <p>I'm creating a Color Picker tool and for the HSL slider, I need to be able to convert RGB to HSL. When I searched SO for a way to do the conversion, I found this question <a href="https://stackoverflow.com/questions/2353211/hsl-to-rgb-color-conversion">HSL to RGB color conversion</a>.</p>
<p>While it provides a function to do conversion from RGB to HSL, I see no explanation to what's really going on in the calculation. To understand it better, I've read the <a href="https://en.wikipedia.org/wiki/HSL_and_HSV" rel="noreferrer">HSL and HSV</a> on Wikipedia.</p>
<p>Later, I've rewritten the function from the "HSL to RGB color conversion" using the calculations from the "HSL and HSV" page.</p>
<p>I'm stuck at the calculation of hue if the R is the max value. See the calculation from the "HSL and HSV" page:</p>
<p><a href="https://i.stack.imgur.com/c6FL6.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/c6FL6.jpg" alt="enter image description here"></a></p>
<p>This is from another <a href="https://nl.wikipedia.org/wiki/HSL_(kleurruimte)#Omzetting_van_RGB_naar_HSL" rel="noreferrer">wiki page</a> that's in Dutch:</p>
<p><a href="https://i.stack.imgur.com/VJrSc.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/VJrSc.jpg" alt="enter image description here"></a></p>
<p>and this is from the <a href="https://stackoverflow.com/a/9493060/2202732">answers</a> to "HSL to RGB color conversion":</p>
<pre><code>case r: h = (g - b) / d + (g < b ? 6 : 0); break; // d = max-min = c
</code></pre>
<p>I've tested all three with a few RGB values and they seem to produce similar (if not exact) results. What I'm wondering is are they performing the same thing? Will get I different results for some specific RGB values? Which one should I be using?</p>
<pre><code>hue = (g - b) / c; // dutch wiki
hue = ((g - b) / c) % 6; // eng wiki
hue = (g - b) / c + (g < b ? 6 : 0); // SO answer
</code></pre>
<p></p>
<pre><code>function rgb2hsl(r, g, b) {
// see https://en.wikipedia.org/wiki/HSL_and_HSV#Formal_derivation
// convert r,g,b [0,255] range to [0,1]
r = r / 255,
g = g / 255,
b = b / 255;
// get the min and max of r,g,b
var max = Math.max(r, g, b);
var min = Math.min(r, g, b);
// lightness is the average of the largest and smallest color components
var lum = (max + min) / 2;
var hue;
var sat;
if (max == min) { // no saturation
hue = 0;
sat = 0;
} else {
var c = max - min; // chroma
// saturation is simply the chroma scaled to fill
// the interval [0, 1] for every combination of hue and lightness

case r:
// hue = (g - b) / c;

Intellij Java 2016 & Maven : how to embed dependencies in JAR? | <p>I'm using Intellij Java 2016.2.2 and Maven to create a very simple Java console application.</p>
<p>I want to add an external library, so I add my dependency in Maven like this:</p>
<pre><code><dependency>
<groupId>jline</groupId>
<artifactId>jline</artifactId>
<version>2.12</version>
</dependency>
</code></pre>
<p>It works fine when I run it in the IDE, but not in an external console (I have the following error: <em>java.lang.NoClassDefFoundError</em>).</p>
<p>I checked and for some reason, the external JAR is not added in the JAR I just generated. I also tried many things in "File -> Project Structure", but still not working...</p>
<p>I just want to build my JAR with my dependencies in it, so I can simply run my application in a console using:</p>
<pre><code>java -jar myproject.jar
</code></pre>
<p>How can I do that? Thanks for your help!</p> | 0 |
Retrofit Returning Null Response Body | <p>I am trying to make a call to the FlickR API and am having difficulty as the response.body() is returning null.</p>
<p>I am not sure if it relates to my JSON/POJO mapping, but I cannot figure out how to access the response from Retrofit when I make the call to FlickR. I know that my call is being completed successfully as I am actually able to view the JSON through the logging interceptor.</p>

I just wanted to let everyone know that I figured it out! Apparently my parents put some insanely powerful parental control software on my computer a few years ago and I forgot it was there. After uninstalling, Android Studio now works flawlessly. The software basically blocked all unknown traffic coming in and out of most of the ports. Anyway, thank you to everyone for the help.

visualization of convolutional layer in keras model | <p>I created a model in Keras (I am a newbie) and somehow managed to train it nicely. It takes 300x300 images and try to classify them in two groups.</p>
<pre><code># size of image in pixel
img_rows, img_cols = 300, 300
# number of classes (here digits 1 to 10)
nb_classes = 2
# number of convolutional filters to use
nb_filters = 16
# size of pooling area for max pooling
nb_pool = 20
# convolution kernel size
nb_conv = 20
X = np.vstack([X_train, X_test]).reshape(-1, 1, img_rows, img_cols)
y = np_utils.to_categorical(np.concatenate([y_train, y_test]), nb_classes)
# build model
model = Sequential()
model.add(Convolution2D(nb_filters, nb_conv, nb_conv, border_mode='valid', input_shape=(1, img_rows, img_cols)))
model.add(Activation('relu'))
model.add(Convolution2D(nb_filters, nb_conv, nb_conv))
model.add(Activation('relu'))
model.add(MaxPooling2D(pool_size=(nb_pool, nb_pool)))
model.add(Dropout(0.25))
model.add(Flatten())
model.add(Dense(64))
model.add(Activation('relu'))
model.add(Dropout(0.5))
model.add(Dense(nb_classes))
model.add(Activation('softmax'))
# run model
model.compile(loss='categorical_crossentropy', optimizer='adadelta', metrics=['accuracy'])

<p>Now I would like to visualize the second convolutional layer and if possible also the first dense layer.

How to open PDF file in vb.net? | <p>Our system is progressing so far so good then I (the programmer) hit a wall again. I tried to convert all the ordinances into .pdf files; here's what I code:</p>
<pre><code>Private Sub LinkLabel1_LinkClicked(sender As Object, e As LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked
e.Link.Visited = True
Dim data1 As String = CType(e.Link.LinkData, String)
Process.Start(data1)
End Sub
Private Sub FullText_Load(sender As Object, e As EventArgs) Handles MyBase.Load
LinkLabel1.Links.Add(13, 13, "C:\Users\Bagiuz\Desktop\CAPSTONE\Data\PDF\City Ordinance No. 2010-215.pdf")
End Sub
</code></pre>
<p>( The code above is my first try, it work but it will open pdf reader if I click the link label; it's okay but what I want is to open the pdf file inside the vb.net not just linking it to a pdf reader)</p>
<hr>
<p>The next step I did was watch a video abour=t merging pdf into vb.net and I didn't really understand it cause the user (in the video) use a "SaveFileDialog" and inserted a "Image Viewer CP Gold ActiveX Control" this thing can be found in the COM Components after right clicking the SaveFileDialog Control. So as I was saying I tried it and it work but nothing happens, I conclude that it didn't display because he use SaveFileDialog.</p>
<hr>
<p>The last step I did was using a "OpenFileDialog"</p>
<pre><code>Dim OpenFileDialog As New OpenFileDialog
OpenFileDialog.InitialDirectory = My.Computer.FileSystem.SpecialDirectories.MyDocuments
OpenFileDialog.Filter = "PDF Files (*.pdf) |*.pdf|All Files (*.*)|*.*"
If (OpenFileDialog.ShowDialog(Me) = System.Windows.Forms.DialogResult.OK) Then
Dim FileName As String = OpenFileDialog.FileName
Process.Start(OpenFileToolStripMenuItem.Text)
End If
</code></pre>
<p>it work but I can't open the file. </p>
<hr>
<p>Im getting confused on what should I do, Can someone please help me with this? I'll gladly appreciate it :)
Someone suggested that I should check out .net pdf viewers but I don't get it

How do you control the size of the output file? | <p>In spark, what is the best way to control file size of the output file. For example, in log4j, we can specify max file size, after which the file rotates. </p>
<p>I am looking for similar solution for parquet file. Is there a max file size option available when writing a file?</p>
<p>I have few workarounds, but none is good. If I want to limit files to 64mb, then One option is to repartition the data and write to temp location. And then merge the files together using the file size in the temp location. But getting the correct file size is difficult.</p> | 0 |
401 Unauthorized error when accessing webapi from angular | <p>I need to capture a user's domain\username when they access my webapi app. On my dev machine I have my webapi at <code>localhost:10570</code> and my angularjs website which makes calls to the webservice at <code>localhost:34575</code>.</p>
<p>If I make a call directly to my webapi app everything works fine. I can see the users domain and username and the service returns the requested data as JSON. But if I access my angularjs site and angular makes the call to webapi then I get 401 unauthorized for every call against the service.</p>
<p>In my WebApi app's web.config I have:</p>
<pre><code><system.web>
<compilation debug="true" targetFramework="4.5.2" />
<httpRuntime targetFramework="4.5.2" />
<authentication mode="Windows" />

nginx udp proxy pass ip | <p>Looking for some guidance on NGINX and passing the source IP address to backend servers. So far I have found config on how to do this for http/s requests but not for TCP/UDP load balancing to non http/s ports. </p>

What happens if I rebase after pushing? | <p>I always hear that it's something scary and something I should never do. For example, here's how the pull dialog looks like in SourceTree:</p>
<p><a href="https://i.stack.imgur.com/BjUmj.png" rel="noreferrer"><img src="https://i.stack.imgur.com/BjUmj.png" alt="enter image description here"></a></p>
<p>So I'm curious, what would happen and how bad would it be if I had pushed changes, then rebased and pushed them again? And how to fix the repository if I'd break it this way?</p> | 0 |
How to get a complex number as a user input in python? | <p>I'm trying to build a calculator that does basic operations of complex numbers. I'm using code for a calculator I found online and I want to be able to take user input as a complex number. Right now the code uses int(input) to get integers to evaluate, but I want the input to be in the form of a complex number with the format complex(x,y) where the user only needs to input x,y for each complex number. I'm new to python, so explanations are encouraged and if it's something that's just not possible, that'd be great to know. Here's the code as it is now:</p>
<pre><code># define functions
def add(x, y):
"""This function adds two numbers"""
return x + y
def subtract(x, y):
"""This function subtracts two numbers"""
return x - y
def multiply(x, y):
"""This function multiplies two numbers"""
return x * y
def divide(x, y):
"""This function divides two numbers"""
return x / y
# take input from the user
print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")
choice = input("Enter choice: 1, 2, 3, or 4: ")
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
if choice == '1':
print(num1,"+",num2,"=", add(num1,num2))
elif choice == '2':
print(num1,"-",num2,"=", subtract(num1,num2))
elif choice == '3':
print(num1,"*",num2,"=", multiply(num1,num2))
elif choice == '4':
print(num1,"/",num2,"=", divide(num1,num2))
else:
print("Invalid input")

angularjs ui-select-choices dropdown aphabetical order depending on the input given | <p>I'm using <a href="https://github.com/angular-ui/ui-select" rel="nofollow noreferrer">https://github.com/angular-ui/ui-select</a> for the website I'm working on. Currently the code is as follows:</p>
<pre><code> <ui-select ng-model="model.states">
<ui-select-match placeholder="State">
{{$item.Name}}
</ui-select-match>
<ui-select-choices repeat="item.Code as item in statesArray | filter:$select.search">
{{item.Name}}
</ui-select-choices>
</ui-select>
</code></pre>
<p>When I type anything in the input field, for example "a", ui-select-choices shows all the fields containing "a" (by default). What I want to do is, I want to show all the states starting with "a" only. If nothing is typed in the input box, then show all the fields in alphabetical order. Can someone please propose a solution? I saw few other posts but no one has answered this question yet. Thanks in advance.</p>
<h1>Example</h1>
<p>Here's an example, suppose states array has states like California, Connecticut, Alaska, Arizona, New York.</p>
<p>If nothing is typed in the input field, dropdown should show Alaska, Arizona, California, Connecticut, New York (which can be achieved using orderBy filter).</p>
<p>If user types "a" in the input field, dropdown should show Alaska, Arizona and no other fields as Alaska and Arizona are only fields starting with "a".
If user types "c", dropdown should show California, Connecticut.
If user types "ca", dropdown should show California only as it only matches the input string given.</p> | 0 |
center text in bootstrap navbar | <p>I've seen several answers of this sort on StackOverflow, but none of them suit my purposes. What I'm trying to do is center <strong>text</strong> in the navbar. All of the other answers I've seen dealt with centering a nav <code>ul</code>. What I want to do is center a <code>.nav-text</code> in the navbar. I tried centering the text with <code>text-align: center</code> on pretty much every element in the navbar (<code>.navbar</code>, <code>.container</code>, <code>.navbar-collapse</code>) but none of them work.</p>
<p><strong>HTML</strong></p>
<pre><code><div id="navbar" style="opacity: 0;">
<nav class="navbar navbar-default navbar-fixed-top" style="text-align: center;">
<div class="container" style="text-align: center;">
<div class="collapse navbar-collapse" style="text-align: center;">
<ul class="nav navbar-nav">
<li><a href="/">My Website</a></li>
<li><a href="#">About</a></li>

docker login not working with nexus 3 private registry | <p><a href="https://i.stack.imgur.com/nlGWN.png" rel="noreferrer">Nexus UI Config</a></p>
<p>I am running Nexus Repository Manager OSS 3.0.1-01 on a linux VM
On that VM, I have nginx working to reserve proxy http requests as https.
My SSL key is signed by a trusted CA
I created a maven repository, which works without issues, whenever I have a client machine publish to it.</p>
<p>Also on this client machine, when I use my docker client, and do a docker login. I am receiving all kinds of errors.</p>
<p>I am following these instructions <a href="https://books.sonatype.com/nexus-book/3.0/reference/docker.html#_accessing_repositories" rel="noreferrer">https://books.sonatype.com/nexus-book/3.0/reference/docker.html#_accessing_repositories</a>
Specifically Section 9.2 and honestly, I've spent the last 2 days getting nowhere. </p>
<p>I've read over everything that's mentioned here:
<a href="https://stackoverflow.com/questions/33021350/trouble-connecting-to-docker-registry-stored-on-nexus-3-preview-on-azure-vm">Trouble connecting to Docker registry stored on Nexus 3 Preview on Azure VM</a>
But that setup the user explains confuses me.</p>
<p>For the setup we are trying to achieve insecure settings by adding <code>--insecure-registry</code> to <code>/etc/default/docker</code> file, is simply not
an option.</p>
<p>I've tried to follow multiple tutorials just to understand the inner workings of the docker registry but I haven't been able to piece
it together. I've looked at following this to a certain extent:<a href="https://www.digitalocean.com/community/tutorials/how-to-set-up-a-private-docker-registry-on-ubuntu-14-04" rel="noreferrer">https://www.digitalocean.com/community/tutorials/how-to-set-up-a-private-docker-registry-on-ubuntu-14-04</a></p>
<p>I have used additional responses in stackoverflow to help me troubleshoot
<a href="https://stackoverflow.com/questions/31599634/malformed-http-response-with-docker-private-registry-v2-behind-an-nginx-proxy">malformed HTTP response with docker private registry (v2) behind an nginx proxy</a></p>
<p>But honestly I can't say I've found anything that's made understanding this straight forward. NGINX isn't reporting any error logs
in <code>/var/log/nginx/errors.log</code>, the access logs look like basic 'GETS', each time I attempt a docker login.
The docker logs in
<code>/var/log/upstart/docker.log</code> report the same errors that I'm illustrating below with the 404 errors.
Also followed this issue on github to see if that was any help github com/docker/docker/issues/8410 . Any assistance to get me to able to perform a successful docker login to this private nexus 3 repo would be amazing.</p>
<p>Now maybe I'm a bit confused with everything I've been reading to get my docker client to work successfully with this nexus repo, but is it required that I setup a docker(group) repo and that is the source of my issue? Or is it okay for me to just have a docker(hosted) repo. Because as of right now I only have a docker(hosted) repo. The Nexus documentation didn't give me the impression that a group repo was also required to get things to work.</p>
<p>Last but not least, I hope my question is specific enough, and I hope that you guys see I've made some effort here. I really did try!</p>
<p>When I login, I am using the local admin user, with the default admin password.
First let me present the issues:</p>
<p>If I try without a port, i get the following --</p>
<pre><code>root:~# docker login box.company.net
Error response from daemon: Login:
<!DOCTYPE html>
<html>
<head>
<title>404 - Nexus Repository Manager</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</code></pre>
<p>With the HTTP port of 4444, i get the following</p>
<pre><code>root:~# docker login box.company.net:4444
Error response from daemon: Get https://box.company.net:4444/v1/users/: `http: server gave HTTP response to HTTPS client`
</code></pre>
<p>If I add HTTPS in the Nexus UI to 4445, then I run</p>
<pre><code>root:~# docker login box.company.net:4445
Error response from daemon: Get https://box.company.net:4445/v1/users/: dial tcp x.x.x.x:4445: getsockopt: connection refused

JavaFX 8 - Tabpanes and tabs with separate FXML and controllers for each tab | <p>I hope to get some answers regarding having fx:include statements for each tab in a tabpane. I have managed with ease to get content to show up BUT referencing methods of the associated controller class simply gives me a nullpointerreference exception no matter how I structure it. The controllers of the included FXML layouts do not have neither constructor not initialize() methods, are they needed? I tried some different things but always got the same exception.</p>
<p>What I simply did was add a change listener to the tabpane and when a tab was pressed I wanted to populate some textfields with some values gotten from a globally accessible arraylist. Note: the arraylist is not the issue, performing this operation using the main controller works fine. </p>
<p>I'm going to add a code example shortly but cannot right now. Please let me know if you need more info, otherwise I'll post the code later today. </p>
<p>*Edit, here is my code example, taken from another thread here on StackOverflow.

<p>The above onAction for both FooTab and BarTab works with their respective buttons. When this method (handleButton) is references from the Main controller, that's when I get an exception.</p> | 0 |

Validate a base64 decoded image in laravel | <p>Im trying to get a image from a PUT request for update a user picture(using postman), and make it pass through a validation in Laravel 5.2, for making the call in postman use the following url: </p>
<p><a href="http://localhost:8000/api/v1/users?_method=PUT" rel="noreferrer">http://localhost:8000/api/v1/users?_method=PUT</a></p>
<p>and send the image string in the body, using a json like this: </p>
<pre><code>{
"picture" : "data:image/png;base64,this-is-the-base64-encode-string"
}
</code></pre>
<p>In the controller try a lot of differents ways for decode the image and try to pass the validation:</p>
<ol>
<li><p>First I tried this: </p>
<pre><code>$data = request->input('picture');
$data = str_replace('data:image/png;base64,', '', $data);
$data = str_replace(' ', '+', $data);
$image = base64_decode($data);
$file = app_path() . uniqid() . '.png';
$success = file_put_contents($file, $image);
</code></pre></li>
<li><p>Then I tried this:</p>
<pre><code>list($type, $data) = explode(';', $data);
list(, $data) = explode(',', $data);
$data = base64_decode($data);
$typeFile = explode(':', $type);
$extension = explode('/', $typeFile[1]);
$ext = $extension[1];
Storage::put(public_path() . '/prueba.' . $ext, $data);
$contents = Storage::get(base_path() . '/public/prueba.png');
</code></pre></li>
<li><p>Try to use the intervention image library (<a href="http://image.intervention.io/" rel="noreferrer">http://image.intervention.io/</a>) and don't pass: </p>
<pre><code>$image = Image::make($data);
$image->save(app_path() . 'test2.png');
$image = Image::make(app_path() . 'test1.png');
</code></pre></li>
</ol>
<p>This is the validation in the controller:</p>
<pre><code> $data = [
'picture' => $image,
'first_name' => $request->input('first_name'),
'last_name' => $request->input('last_name')
];
$validator = Validator::make($data, User::rulesForUpdate());
if ($validator->fails()) {
return $this->respondFailedParametersValidation('Parameters failed validation for a user picture');
}
</code></pre>
<p>this is the validation in the User-model: </p>
<pre><code>public static function rulesForUpdate() {
return [
'first_name' => 'max:255',
'last_name' => 'max:255',
'picture' => 'image|max:5000|mimes:jpeg,png'
];
}

Code or command to use embedded resource in Visual Studio | <p>Can somebody provide me a starting point or code to access an embedded resource using C#?</p>
<p>I have successfully embedded a couple of batch files, scripts and CAD drawings which I would like to run the batch and copy the scripts and CAD files to a location specified in the batch file. </p>

p.StartInfo.FileName = AppDomain.CurrentDomain.BaseDirectory + "\\Batchfile.bat";
p.Start();

pandas read_csv and keep only certain rows (python) | <p>I am aware of the skiprows that allows you to pass a list with the indices of the rows to skip. However, I have the index of the rows I want to keep.</p>

<pre><code> A B
0 1 2
1 3 4
2 5 6
3 7 8
4 9 0
</code></pre>
<p>The list of indices i would like to load are only 2,3, so</p>
<pre><code>index_list = [2,3]
</code></pre>
<p>The input for the skiprows function would be [0,1,4]. However, I only have available [2,3].</p>

How can I compile my Typescript into a single JS file with no module loading system? | <p>I have a small Typescript project of about 10 <code>ts</code> files. I want to compile all my files into <code>es5</code> and into a single <code>es5</code> file called <code>all.js</code>.</p>
<p>Currently, with my <code>tsconfig.json</code> set up as </p>
<pre><code>{
"compilerOptions": {
"module": "system",
"target": "es5",
"outFile": "./all.js"
}
</code></pre>
<p>everything is getting compiled, but each file is being wrapped by </p>
<pre><code>System.register("SomeTSFile", [], function(exports_4, context_4) {
...
}
</code></pre>
<p>SystemJS looks cool but I am not in the mood to learn it now and I don't believe it is necessary. If I could get all my JS into one file, that will be perfectly sufficient for my needs. </p>
<p>If I remove <code>"module": "system",</code>from my compiler options, my <code>all.js</code> file comes out completely blank. Apparently, this is because for some reason, <a href="https://www.typescriptlang.org/docs/handbook/compiler-options.html" rel="noreferrer">you cannot use <code>"modules": none</code> when outputting to one file</a>. (I don't get why)</p>
<p><strong>How can I compile all the TS into one JS file without having to involve SystemJS or any other complications?</strong></p> | 0 |
Passing parameters to a trait | <p>I want to model the game of chess.
For that, I want to make an abstract class, <code>Piece</code> which takes a player and a position as arguments. From that, I want to extend to other classes such as <code>Pawn</code>:</p>
<pre><code>trait Piece(player: Int, pos: Pos) = {
def spaces(destination: Pos): List[Pos]
}
case class Pawn extends Piece = {
//some other code
}
</code></pre>
<p>However, I think I'm not allowed to pass parameters to a trait, like this <code>trait Piece(player: Int, pos: Pos)</code>.</p>
<p>So how can I have an abstract class <code>Piece</code> that has fields?</p> | 0 |

Get principal in Spring Boot resource server from JWT token | <p>I have a separate auth server and a resource server - both Spring Boot applications. I am using OAuth2 with JWT tokens for authentication and authorisation. </p>
<p>I can get a token by accessing the auth server:</p>
<pre><code>curl -X POST --user 'client:secret' -d 'grant_type=password&username=john&password=123' http://localhost:9000/auth-server/oauth/token
</code></pre>
<p>and use it when getting a resource from the resource server (running on different server) by attaching the token to the request header.</p>
<p>What is unclear to me though, is to determine which user is logged in in the resource server.</p>
<p>In the auth server, I can do something like this:</p>
<pre><code>@RequestMapping("/user")
public Principal user(Principal user) {
return user;
}
</code></pre>
<p>and this endpoint will get me the current user based on the token used. If I try to do the same thing in the resource server though, I only get empty response.</p>
<p>I need to get the id of the authenticated user somehow in the resource server to decide whether I should return some data to him (I have some resources which can be accessed only by their owner). </p>
<p>How could I do that? I thought that by using JWT, I don't need to share the same token store.</p>
<p>I can provide code samples if my question is not clear.. I am just looking for a confirmation that my assumption is correct and this behaviour can be achieved - this is my first time experimenting with spring security.</p>
<p>The resource server is linked to the auth server in the application.properties:</p>
<pre><code>security.oauth2.resource.userInfoUri: http://localhost:9000/auth-server/user
</code></pre> | 0 |

Android WebView, err net::Name_Not_Resolved | <p>I have tried searching through the docs and other forums but no success.</p>
<p>I have an android application that is simply a webView that opens up a website as soon as you open the app. However, when connecting to my website I receive an error, <strong>net::ERR_NAME_NOT_RESOLVED.</strong> Changed the loadUrl with a popular website like Google.com and it worked just fine.</p>
<p>My website works fine from Google Chrome, on dekstop, etc.. just not in WebView.. Can anyone help explain why? </p>
<p><strong>On Another note</strong>, I am also trying to find a way to manually enter the dns settings, hoping this would resolve the matter. Any tips or pointing me down the right path is very much appreciated.</p>

Git hooks : applying `git config core.hooksPath` | <p>I have a git repository with a pre-commit hook set up :</p>

<li>the new pre-commit script doesn't run on commit</li>
<li>the old pre-commit script still runs on commit if I leave it in <code>my-repo/.git/hooks</code></li>
<li>running <code>git config --get core.hooksPath</code> in <code>my-repo</code> outputs <code>./git-config/hooks</code></li>

How to download multiple files in Google Cloud Storage | <p>Scenario: there are multiple folders and many files stored in storage bucket that is accessible by project team members.

What are the best practice for domain names (dev, staging, production)? | <p>With the rise of containers, Kuberenetes, 12 Factor etc, it has become easier to replicate an identical environment across dev, staging and production. However, what there appears to be no common standard to domain name conventions.</p>
<p>As far as I can see it, there are two ways of doing it:</p>
<ul>
<li>Use subdomains:
<ul>
<li><code>*.dev.foobar.tld</code></li>
<li><code>*.staging.foobar.tld</code></li>
<li><code>*.foobar.tld</code></li>
</ul></li>
<li>Use separate domains:
<ul>
<li><code>*.foobar-dev.tld</code></li>
<li><code>*.foobar-staging.tld</code></li>
<li><code>*.foobar.tld</code></li>
</ul></li>
</ul>
<p>I can see up and downs with both approaches, but I'm curious what the common practise is.</p>
<p>As a side-note, Cloudflare will not issue you certificates for sub-sub domains (e.g. <code>*.stage.foobar.tld</code>).</p> | 0 |
Docker MySQL: create new user | <p>In the <a href="https://hub.docker.com/_/mysql/" rel="nofollow">mysql docker hub page</a> there's a reference on how to create users with:</p>

<pre><code>mysql:
image: mysql:5.7
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: R00t+

<p>Another question; how can I connect to the mysql host from outside the container? Inside the container I can connect using:</p>
<pre><code>$user = 'root';
$pass = 'R00t+';
$server = 'mysql';
$dbh = new PDO( "mysql:host=$server", $user, $pass );

didReceiveRemoteNotification not called, iOS 10 | <p>In iOS 9.3, the <code>didReceiveRemoteNotification</code> method gets called on both of the following occasions. </p>
<p>1) When the push notification is received
2) When the user launches the app by tapping on the notification.</p>
<p>But on iOS 10, I notice that the <code>didReceiveRemoteNotification</code> method does <strong>NOT</strong> fire when the user launches the app by tapping on the notification. It's called only when the notification is received. Hence, I cannot do any further action after the app is launched from notification.</p>

Loading Assemblies from NuGet Packages | <p>Sometimes in my PowerShell scripts, I need access to a specific DLL, using <code>Add-Type -AssemblyName</code>. However, the DLLs I need aren't always on the machine or in the GAC. For instance, I might want a quick script that uses Dapper to query a database. In these cases, I have been literally copying the DLLs along with the <code>ps1</code> file. I was wondering if this was common/a good idea and whether there was an existing extension that would load up NuGet packages, store then in a global or local folder and call <code>Add-Type -AssemblyName</code> automatically.</p>
<p>It'd be a lot like using <code>npm</code> or <code>pip</code> in Node.js or Python, respectively.</p>
<h2>Update</h2>
<p>I did some research and there's nothing built-in to older versions of PowerShell. I made some progress trying to write one from scratch using the <code>nuget.exe</code></p>
<pre><code>&"$(Get-Location)/nuget.exe" install $packageName -Version $version -OutputDirectory "$(Get-Location)/packages" -NoCache -NoInteractive
</code></pre>
<p>This will download a given package/version under a "packages" folder in the current folder, along with any of its dependencies. However, it looks like it downloads every framework version, with no obvious way to tell which one to use for your given environment.</p>
<p>Otherwise, you could just loop through the results and call Add-Type:</p>
<pre><code>Get-ChildItem .\packages\ -Recurse -Filter "*.dll" | % {
try
{
Add-Type -Path $_.FullName
}
catch [System.Exception]
{
}
}
</code></pre>
<p>I tried using the <code>restore</code> command using a <code>project.json</code> file to see if I could control the framework version with no luck. This is just too hacky for me.</p>
<p>I'll check out @crownedjitter's suggestion of using PowerShell 5.</p>
<h2>Update</h2>
<p>Using @crownedjitter's suggestion, I was able to eventually register the PackageManagement module with NuGet (see comments below). With the following command, I was able to reproduce what the <code>Nuget.exe</code> command above was doing:</p>
<pre><code>Install-Package Dapper -Destination packages
</code></pre>
<p>Obviously, this is a lot shorter. Problem is it has the same limitation; it brings down every framework version of a package. If this includes .NET core, it brings down a good deal of the .NET core framework with it! There doesn't appear to be a way to specify a target framework (a.k.a, .NET 4.5.1 or below).</p>

<p>I am wondering if there is a way to determine which NuGet package folder(s) to load the DLLs from based on PowerShell's current <code>$PSVersionTable.CLRVersion</code> field.</p> | 0 |
Jackson serializes a ZonedDateTime wrongly in Spring Boot | <p>I have a simple application with Spring Boot and Jetty. I have a simple controller returning an object which has a Java 8 <code>ZonedDateTime</code>:</p>
<pre><code>public class Device {
// ...
private ZonedDateTime lastUpdated;
public Device(String id, ZonedDateTime lastUpdated, int course, double latitude, double longitude) {
// ...
this.lastUpdated = lastUpdated;
// ...
}
public ZonedDateTime getLastUpdated() {
return lastUpdated;
}
}
</code></pre>
<p>In my <code>RestController</code> I simply have: </p>
<pre><code>@RequestMapping("/devices/")
public @ResponseBody List<Device> index() {
List<Device> devices = new ArrayList<>();
devices.add(new Device("321421521", ZonedDateTime.now(), 0, 39.89011333, 24.438176666));
return devices;
}
</code></pre>
<p>I was expecting the <code>ZonedDateTime</code> to be formatted according to the ISO format, but instead I am getting a whole JSON dump of the class like this:</p>
<pre><code>"lastUpdated":{"offset":{"totalSeconds":7200,"id":"+02:00","rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]}},"zone":{"id":"Europe/Berlin","rules":{"fixedOffset":false,"transitionRules":[{"month":"MARCH","timeDefinition":"UTC","standardOffset":{"totalSeconds":3600,"id":"+01:00","rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]}},"offsetBefore":{"totalSeconds":3600,"id":"+01:00","rules":{"fixedOffset":true,"transitionRules":[],"transitions":[]}},"offsetAfter":{"totalSeconds":7200,"id":"+02:00", ...
</code></pre>
<p>I just have a <code>spring-boot-starter-web</code> application, using <code>spring-boot-starter-jetty</code> and excluding <code>spring-boot-starter-tomcat</code>.</p>
<p>Why is Jackson behaving like this in Spring Boot?</p>
<p>** UPDATE **</p>
<p>For those looking for a full step by step guide how to solve this I found this after asking the question:
<a href="http://lewandowski.io/2016/02/formatting-java-time-with-spring-boot-using-json/">http://lewandowski.io/2016/02/formatting-java-time-with-spring-boot-using-json/</a></p> | 0 |
How to run an electron app with arguments? | <p>My app is electron with a <code>BrowserWindow</code> loading a local page index.html.<br>
I call <code>npm run start</code> a script to run <code>electron main.js</code> , the app opens and the html loaded.<br>
Can I add an argument to the script that will load different html file into the <code>BrowserWindow</code> ? </p>
<p>In the main.js file the code is :</p>
<pre class="lang-js prettyprint-override"><code>function createWindow () {
// Create the browser window.
mainWindow = new BrowserWindow({
webPreferences:{
webSecurity:false
},
fullscreen : false });//, alwaysOnTop : true , kiosk : true })
mainWindow.setMenu(null);
// and load the index.html of the app.
let url = `file://${__dirname}/index.html`; \\ index.html should be determined by argument passed at start.
mainWindow.loadURL(url,loadOptions);
// Open the DevTools.
mainWindow.webContents.openDevTools();
// Emitted when the window is closed.
mainWindow.on('closed', function () {
// Dereference the window object, usually you would store windows
// in an array if your app supports multi windows, this is the time
// when you should delete the corresponding element.
mainWindow = null;
});

Python - Kivy: AttributeError: 'super' object has no attribute '__getattr__' when trying to get self.ids | <p>I wrote a code for a kind of android lock thing, whenever I try to get an specific ClickableImage using the id it raises the following error:</p>
<pre><code>AttributeError: 'super' object has no attribute '__getattr__'
</code></pre>
<p>I've spent hours trying to look for a solution for this problem, I looked other people with the same issue, and people told them to change the site of the builder, because it needed to be called first to get the ids attribute or something like that, but everytime I move the builder, it raises the error "class not defined". Any clues?</p>

Why is the TypeScript compiler ignoring tsconfig.json? | <p>I have this file, pasted from a tutorial (and let's face it, the disparity between docs, tuts, and examples is astounding):</p>
<p>/scripts/tsconfig.json:</p>
<pre><code>{
"compilerOptions": {
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"module": "commonjs",
"noEmitOnError": true,
"noImplicitAny": false,
"outDir": "../wwwroot/appScripts/",
"removeComments": false,
"sourceMap": true,
"target": "es5",
"moduleResolution": "node"
},
"exclude": [
"node_modules",
"typings/index",
"typings/index.d.ts"
]
}
</code></pre>
<p>Options are set to compile on save, but whenever I save a TypeScript file, the JavaScript output ends up 'under', or 'attached to', the source file:</p>
<pre><code>TypeScript
|
--test.ts
|
--test.js
</code></pre>
<p>, and that is physically in the same directory as the source, <code>/TypeScript</code>. If <code>tsconfig.json</code> is missing, the compiler complains, but when it's present, and it definitely is, the compiler ignores the <code>"outDir": "../wwwroot/appScripts/"</code> setting.</p>
<p>I am really to new to Gulp, but the Gulp task looks OK to me:</p>
<pre><code>var tsProject = ts.createProject('scripts/tsconfig.json');
gulp.task('ts', function (done) {
//var tsResult = tsProject.src()
var tsResult = gulp.src([
"scripts/*.ts"
])
.pipe(ts(tsProject), undefined, ts.reporter.fullReporter());
return tsResult.js.pipe(gulp.dest('./wwwroot/appScripts'));
});

Restrict scipy.optimize.minimize to integer values | <p>I'm using <code>scipy.optimize.minimize</code> to optimize a real-world problem for which the answers can only be integers. My current code looks like this: </p>
<pre><code>from scipy.optimize import minimize
def f(x):
return (481.79/(5+x[0]))+(412.04/(4+x[1]))+(365.54/(3+x[2]))+(375.88/(3+x[3]))+(379.75/(3+x[4]))+(632.92/(5+x[5]))+(127.89/(1+x[6]))+(835.71/(6+x[7]))+(200.21/(1+x[8]))
def con(x):
return sum(x)-7
cons = {'type':'eq', 'fun': con}
print scipy.optimize.minimize(f, [1,1,1,1,1,1,1,0,0], constraints=cons, bounds=([0,7],[0,7],[0,7],[0,7],[0,7],[0,7],[0,7],[0,7],[0,7]))
</code></pre>
<p>This yields: </p>
<pre><code>x: array([ 2.91950510e-16, 2.44504019e-01, 9.97850733e-01,
1.05398840e+00, 1.07481251e+00, 2.60570253e-01,
1.36470363e+00, 4.48527831e-02, 1.95871767e+00]
</code></pre>
<p>But I want it optimized with integer values (rounding all <code>x</code> to the nearest whole number doesn't always give the minimum). </p>
<p>Is there a way to use <code>scipy.optimize.minimize</code> with only integer values?</p>
<p>(I guess I could create an array with all possible permutations of <code>x</code> and evaluate f(x) for each combination, but that doesn't seem like a very elegant or quick solution.)</p> | 0 |
Application startup code in ASP.NET Core | <p>Reading over the <a href="https://docs.asp.net/en/latest/fundamentals/startup.html" rel="noreferrer">documentation for ASP.NET Core</a>, there are two methods singled out for Startup: Configure and ConfigureServices.</p>
<p>Neither of these seemed like a good place to put custom code that I would like to run at startup. Perhaps I want to add a custom field to my DB if it doesn't exist, check for a specific file, seed some data into my database, etc. Code that I want to run once, just at app start.</p>
<p>Is there a preferred/recommended approach for going about doing this?</p> | 0 |
Rails: Unpermitted parameter in Rails 5 | <p>First of all I want simply get an object inside the current object that I'm sending to my <em>backend</em>.</p>
<p>I have this simple <code>JSON</code> (generated from a form):</p>
<pre><code>{
"name": "Project 1",
"project_criteria": [
{
"name": "Criterium 1",
"type": "Type 1",
"benefit": "1"
},
{
"name": "Criterium 2",
"type": "Type 2",
"benefit": "3"
}
]
}
</code></pre>
<p>My <code>classes</code>:</p>
<pre><code>class Project < ApplicationRecord
has_many :project_criteria
accepts_nested_attributes_for :project_criteria
end
class ProjectCriterium < ApplicationRecord
belongs_to :project
end
</code></pre>
<p><strong>ProjectsController:</strong></p>
<pre><code>def project_params
params.require(:project).permit(:name, project_criteria: [] )
end
</code></pre>
<p>But I still can't access <code>project_criteria</code> parameter as you can see below:</p>
<pre><code>Started POST "/projects" for 127.0.0.1 at 2016-08-19 16:24:03 -0300

Unpermitted parameter: project_criteria # <-----------
</code></pre>
<p><strong>Note:</strong></p>
<p>By the way, I already tried to use <strong>criterium</strong> instead of <strong>criteria</strong>(which <strong>- in my opinion -</strong> is the correct since it should be pluralized) in <code>has_many</code> and <code>accepts_nested_attributes_for</code>, but it also doesn't work.</p>

<p>I think this has nothing to do with Ribbon ConnectTimeout or ReadTimeout. This error is because of the property <strong>"execution.isolation.thread.timeoutInMilliseconds: 60000"</strong>. I have also reduced this property to 10000 ms to test the behavior and got the same exception if the sleep time is more(ex: 12000).</p>
<p><strong>I want to understand Ribbon ConnectTimeout and Read-timeout vs Hystrix timeout and how to test ribbon timeouts in my application. Also if I want different timeouts for different microservices, Do I keep these properties in respective .yml files?.</strong> Any thoughts?</p>
<p>I'm trying to create a document to be used by my team so that it is easy for a developer to know how these timeout options work in Spring cloud.</p>
<p>(It's a lengthy description but to make it clearer I had to write in detail)</p> | 0 |
How do I load a custom bundle in Swift 3 | <p>In Objective-C I was doing this:</p>
<pre><code>NSString *path = [[NSBundle mainBundle] pathForResource:@"LUIImages" ofType:@"bundle"];
path = [[NSBundle bundleWithPath:path] pathForResource:_imageHash ofType:nil];
</code></pre>
<p>But I can't seem to find equivalent in swift 3</p>
<pre><code>let bundlePath: String = Bundle.main.path(forResource: "LiveUI", ofType: "bundle")!
</code></pre>
<p>But what is the next step? Or is there any better way to load a custom bundle?</p> | 0 |
Woocommerce - Display single product attribute(s) with shortcodes in Frontend | <p>i've read many Q/A's here during the last few days, but unfortunately none of them solved my issue.</p>
<p>I'm trying to fetch product attributes and display them on the frontend with a shortcode. I have managed to display ALL available attributes and display them in a list, but i need to select only one or two of them in different locations (thats why using shortcodes). For example like [shortcode_attribute name="brand"].</p>
<p>Any help is highly appreciated!</p>
<p>my code so far:</p>
<pre><code>function tutsplus_list_attributes( $product ) {
global $product;
global $post;
$attributes = $product->get_attributes();
if ( ! $attributes ) {
return;
}
foreach ( $attributes as $attribute ) {
// Get the taxonomy.
$terms = wp_get_post_terms( $product->id, $attribute[ 'name' ], 'all' );
$taxonomy = $terms[ 0 ]->taxonomy;
// Get the taxonomy object.
$taxonomy_object = get_taxonomy( $taxonomy );
// Get the attribute label.
$attribute_label = $taxonomy_object->labels->name;
// Display the label followed by a clickable list of terms.
echo get_the_term_list( $post->ID, $attribute[ 'name' ] , '<div><li class="bullet-arrow">' . $attribute_label . ': ' , ', ', '</li></div>' );
}
}
add_action( 'woocommerce_product_meta_end', 'tutsplus_list_attributes' );
add_shortcode('display_attributes', 'tutsplus_list_attributes');

ImportError: No module named azure.storage.blob (when doing syncdb) | <p>I recently cloned a Django project of mine in a brand new machine, and went about setting up its dependencies. One such dependency was azure storages, for which I followed the advice <a href="https://stackoverflow.com/questions/34405936/getting-importerror-no-module-named-azure-storage-blob-when-doing-python-manage">here</a> and simply did <code>sudo pip install azure</code>. </p>
<p>However, upon `python manage.py syncdb', I keep getting the error:</p>
<blockquote>
<p>ImportError: No module named azure.storage.blob</p>
</blockquote>
<p>I've tried to solely do <code>sudo pip install azure-storage</code> as well, but this doesn't alleviate my problem either. This shouldn't have been this problematic. What do I do?</p> | 0 |
