<p>part-1 has been done sucessfully and but in part -2 when i deploy app im my mobile then i am not getting any <strong>gcm registration token</strong> in toast and neither in logcat.
As i have searched that due to my config.php file i am using ip s=address instead of hostname i had to change my link <strong>from this</strong>

Most standard way to create single page application with Django | <p>I just started working with Django today, and am a little lost in the docs at the moment.</p>
<p>I'd like to create a single page application. I'd like the server to return a single index.html for any request that doesn't match "/api/*".</p>
<p>Can somebody show me what the most standard/accepted way to do this with Django would be? I spent a bit of time trying to Google for similar projects, but didn't have any luck so far.</p> | 2 |
How to programmatically add an active graphics layer to a map? | <p>I'm writing a WPF applicating, in C#, using ArcObjects.</p>
<p>I have an ESRI.ArcGIS.Controls.AxMapControl on my form, and I'm trying to draw some graphics elements on top of it.</p>
<p>The map I'm developing with is a customer-provided mdf of the state of Georgia.</p>
<p>I'm trying an example I found here: <a href="http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#//0001000001rv000000" rel="nofollow">How to interact with map elements</a>.</p>
<pre><code>public void AddTextElement(IMap map, double x, double y)
{
IGraphicsContainer graphicsContainer = map as IGraphicsContainer;
IElement element = new TextElementClass();
ITextElement textElement = element as ITextElement;
//Create a point as the shape of the element.
IPoint point = new PointClass();
point.X = x;
point.Y = y;
element.Geometry = point;
textElement.Text = "Hello World";
graphicsContainer.AddElement(element, 0);
//Flag the new text to invalidate.
IActiveView activeView = map as IActiveView;
activeView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);
}
</code></pre>
<p>It took while to figure out how to project the lat/long of Atlanta to the coordinate system of the map, but I'm pretty sure that I've got it right. The x/y values I'm passing into AddTextElement() are clearly within the Atlanta area, according to the Location data I see when I use the Identify tool on the map.</p>
<p>But I'm not seeing the text. Everything seems to be working correctly, but I'm not seeing the text.</p>
<p>I can see a number of possibilities:</p>
<ul>
<li>The layer I'm adding the TextElement to isn't visible, or doesn't exist.</li>
<li>I need to apply a spatial reference system to the point I'm setting as the TextElement's geometry</li>
<li>The text is drawing fine, but there's something wrong with the font - it's invisibly small, or in a transparent color, etc.</li>
</ul>
<p>Haven't a clue, which.</p>
<p>I was hoping there was something obvious I was missing.</p>
<p>===</p>
<p>As I've continued to play with this, since my original posting, I've discovered that the problem is the scaling - the text is showing up where it should, only unreadably small.</p>
<p>This is what Rich Wawrzonek had suggested.</p>
<p>If I set a TextSymbol class, with a specified Size, the size does apply, and I see me text larger or smaller. Unfortunately, the text still resizes as the map zooms in and out, and my trying to set ScaleText = false doesn't fix it.</p>
<p>My latest attempt:</p>
<pre><code>public void AddTextElement(IMap map, double x, double y, string text)
{
var textElement = new TextElementClass
{
Geometry = new PointClass() { X = x, Y = y },
Text = text,
ScaleText = false,
Symbol = new TextSymbolClass {Size = 25000}
};
(map as IGraphicsContainer)?.AddElement(textElement, 0);
(map as IActiveView)?.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);
}
</code></pre>
<p>I recognize that the above is organized very differently than the way is usually done with ESRI sample code. I find the way ESRI does it to be every difficult to read, but switch from one to another is pretty mechanical.</p>
<p>This is the same function, organized in a more traditional manner. The behavior should be identical, and I'm seeing exactly the same behavior - the text is drawn to a specified size, but scales as the map zooms.</p>
<pre><code>public void AddTextElement(IMap map, double x, double y, string text)
{
IPoint point = new PointClass();
point.X = x;
point.Y = y;
ITextSymbol textSymbol = new TextSymbolClass();
textSymbol.Size = 25000;
var textElement = new TextElementClass();
textElement.Geometry = point;
textElement.Text = text;
textElement.ScaleText = false;
textElement.Symbol = textSymbol;
var iGraphicsContainer = map as IGraphicsContainer;
Debug.Assert(iGraphicsContainer != null, "iGraphicsContainer != null");
iGraphicsContainer.AddElement(textElement, 0);
var iActiveView = (map as IActiveView);
Debug.Assert(iActiveView != null, "iActiveView != null");
iActiveView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);
}
</code></pre>
<p>Any ideas as to why ScaleText is being ignored?</p> | 2 |
How to show date from MonthCalendar to TextBox C# | <p>I have two forms, on one is month, on another is TextBox.
Problem is that I don't get displayed date on the TextBox after selecting it.
To be certain that I wrote working code, I did same thing just on one form, and it works fine.
Set MonthCalendar to public and same with the TextBox where date needs to be displayed.<br>
<a href="https://i.stack.imgur.com/5XzH7.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5XzH7.jpg" alt="enter image description here"></a></p>
<p>Here is the code for Button and for the monthcalendar:</p>
<pre><code>public void mcKalendar_DateChanged()
{
frmNovoVozilo fNv = new frmNovoVozilo();
fNv.txtDatKupovine.Text =
mcKalendar.SelectionRange.Start.ToShortDateString();
}
private void btnDatum_Click(object sender, EventArgs e)
{
frmKalendar fKalen = new frmKalendar();
fKalen.StartPosition = FormStartPosition.CenterScreen;
fKalen.Show();
}
</code></pre>
<p>Did try also DateSelected and it's giving me the same result, nothing.
Thanks upfornt.</p> | 2 |
Why does chrome.contextMenus create multiple entries? | <p>I am using <code>chrome.contextMenus.create</code> function to create context menus in my Chrome extension. But it creates extra options.</p>
<p>I gave permission in my <code>manifest.json</code> file, added this function my <code>background.js</code> file and added it my <code>manifest.json</code> file.</p>
<p>Why this is happening ?</p>
<pre><code>function getword(info,tab) {
console.log("Word " + info.selectionText + " was clicked.");
chrome.tabs.create({

Spring boot @RestController | <p>Is there a step needed, like adding jars to classpath?</p>
<p>I followed this:</p>
<p>10.2.6 Quick start Spring CLI example</p>
<p>Here’s a really simple web application that you can use to test your installation. Create a file called app.groovy:</p>
<pre><code>@RestController
class ThisWillActuallyRun {
@RequestMapping("/")
String home() {
"Hello World!"
}
}
</code></pre>
<p>Then simply run it from a shell:</p>
<pre><code>$ spring run app.groovy
</code></pre>
<p>and get:</p>
<pre><code>startup failed:

Spring MVC: What is an HttpEntity? | <p>I have read the spring docs about the HttpEntity. Accordingly, it represents a Http response/request entity. I arrived in the conclusion that this is the same as a character in a character stream. However, it consists of a header and a body.</p>
<p>Please elaborate about HttpEntity or Http response/request in general. Links are welcome.</p> | 2 |
Cucumber how to find if a feature file has executed? Any Java method? | <pre><code> @Before
public void quit_if_tagged_scenario_failed(Scenario scenario) {
if (!isTagged(scenario) && prevScenarioFailed)
throw new IllegalStateException("An important scenario has failed! Cucumber wants to quit.");
}
</code></pre>
<p>I'm using this method to check if the previuos scenario failed. If failed I want to skip all the scenarios in that feature file.So the problem here is if I’m running two feature files the last scenario in the feature file failed and the first step of next feature will also fails because cucumbers previous scenario from past feature file is failed. Do you know how to handle that kind of situation?
Your help will be greatly appreciated.</p> | 2 |

What commands is required to revert changes made by git mergetool? | <p>I have made some changes to a number of conflicting files as the result of a a <code>git pull</code> command, using the <code>git mergetool</code> command, but I want to revert it back to the state before I made the changes with the mergetool.</p>

stopwatch running in background with service | <p>I'm trying to make a simple stopwatch for Android. It should keep counting time after minimalizing an app. I have put stopwatch logic into Service and I bind this service in <code>MainActivity</code> to get control over it. Counting time runs in separate thread and I'm using messenger to send time back to <code>MainActivity</code>. Everything works good as long as I don't minimize app and go back while stopwatch is running. After that, pressing start/stop runs second thread counting time instead of stopping the first one. Could check what is wrong? Would appreciate :)</p>

Correct way to handle readFile and writeFile exceptions | <p>I'm writing an application in Haskell and would like to display a meaningful error message to the user if <code>readFile</code> or <code>writeFile</code> fails. I'm currently catching <code>IOError</code>s with <code>Control.Exception.tryJust</code> and converting them to human-readable text.</p>
<p>However, I'm having trouble figuring out which errors I should catch and how to extract information from them. For example, assuming "/bin" is a directory and "/bin/ls" is a file, <code>readFile "/bin"</code> and <code>readFile "/bin/ls/asdf"</code> both give "inappropriate type" but (in my opinion) they are different errors. In the case of the first one, I could recover by processing each file within the directory, whereas the second is more like a "does not exist" type of error.</p>
<p>In relation to the previous example, there doesn't seem to be a portable way of catching "inappropriate type" errors. Looking at <a href="https://hackage.haskell.org/package/base-4.9.0.0/docs/src/GHC.IO.Exception.html#IOErrorType" rel="nofollow noreferrer">GHC.IO.Exception</a>, <code>InappropriateType</code> is marked GHC-only so I can't just pattern match on <code>ioeGetErrorType</code>. I could pattern match on <code>ioeGetErrorString</code> but I'm not sure if those strings are always the same across different platforms, compilers, locales, etc.</p>
<p>In summary, my questions are:</p>
<ol>
<li>Which exceptions should I be catching for <code>readFile</code>/<code>writeFile</code>?</li>
<li>Once I have an exception, how should I go about extracting information from it?</li>
<li>Is there a portable way of catching the GHC-only exceptions such as <code>InappropriateType</code>?</li>
</ol>
<p><strong>Update:</strong></p>
<p>Based on @ErikR's answer I'm looking at the fields of <code>GHC.IO.Exception.IOException</code> with the following Haskell program:</p>
<pre><code>import Control.Exception (try)
import GHC.IO.Exception (IOException(..))
import qualified Data.ByteString as B
main :: IO ()
main = do
try (readFile "/nonexistent") >>= printException
try (writeFile "/dev/full" " ") >>= printException
try (readFile "/root") >>= printException
try (readFile "/bin") >>= printException
try (writeFile "/bin" "") >>= printException
try (readFile "/bin/ls/asdf") >>= printException
try (writeFile "/bin/ls/asdf" "") >>= printException
try (B.readFile "/dev/null") >>= printException
-- I have /media/backups mounted as read-only. Substitute your own read-only
-- filesystem for this one
try (writeFile "/media/backups/asdf" "") >>= printException
printException :: Either IOError a -> IO ()
printException (Right _) = putStrLn "No exception caught"
printException (Left e) = putStrLn $ concat [ "ioe_filename = "
, show $ ioe_filename e
, ", ioe_description = "
, show $ ioe_description e
, ", ioe_errno = "
, show $ ioe_errno e
]
</code></pre>
<p>The output on Debian Sid GNU/Linux with GHC 7.10.3 is:</p>
<pre><code>ioe_filename = Just "/nonexistent", ioe_description = "No such file or directory", ioe_errno = Just 2
ioe_filename = Just "/dev/full", ioe_description = "No space left on device", ioe_errno = Just 28
ioe_filename = Just "/root", ioe_description = "Permission denied", ioe_errno = Just 13

two plots from pandas dataframe with different vertical axes on the same figure | <p>i'm trying to plot in python a line plot and a bar plot on the same figure using data from pandas dataframe. i manage to get two axes on the plot and the legend displays two entries, but the first of the plots is not present.</p>
<p>here's my code:</p>
<pre><code>import matplotlib.pyplot as plt
import pandas as pd
ax1 = data[["timestamp", "polarity"]].plot(x="timestamp", kind="bar")
ax1.set_xticks(data["timestamp"].values)
ax1.set_ylabel("polarity")
ax1.set_xlabel("year")
ax2 = ax1.twinx()
data[["timestamp", "revenue"]].plot(x="timestamp", linestyle="-", marker="o", ax=ax2)
ax2.set_ylabel("revenue")
plt.show()
</code></pre>
<p>and this is the plot that i get:</p>
<p><a href="http://i.stack.imgur.com/TvuoU.png" rel="nofollow">plot</a></p>
<p>when i reverse the order in which i plot, i get the following plot:</p>
<p><a href="http://i.stack.imgur.com/3muJt.png" rel="nofollow">plot 2</a></p>
<p>how do i make the plots appear on the same figure?</p>

Why is there a string ID in the data model of Azure Mobile Apps? | <p>I'm working the C# in Azure Mobile Apps trying to learn them. I created the Model to link to my Azure SQL DB, created a DataObject like this:</p>
<pre><code>public class Account : EntityData
{
//public int id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string PhoneNumber { get; set; }
public string Password { get; set; }
public DateTime dtCreated { get; set; }
public Guid oGuid { get; set; }
}
</code></pre>
<p>Notice that I commented out the public int id above; it was giving me a duplicate column error on the query.</p>
<p>Finally, I created a controller using the newly created Account DataObject.</p>
<p>So I ran the application and hit the "tables/Account" function and it returned zero rows (but there is data and I can query it with the user I'm using in the azure mobile app).</p>
<p>I then noticed the model schema as this:</p>
<pre><code>[
{
"id": 0,
"FirstName": "string",
"LastName": "string",

<p>There's a couple of issues I see with the configured model (and I don't know where some of the columns are coming from...)</p>
<p>First, the id is listed twice, once as an int (which has to be mine) and another id as string and I have no idea where that came from.</p>
<p>Also, in the DB, the oGuid is of type uniqueIdentifier; not string. This may or may not be an issue because I can't test yet. </p>
<p>Then there are the other columns that just do not exist in my DB including CreatedAt (datetime), UpdatedAt (datetime), Version (string) and Deleted (bit).</p>
<p>I'm thinking the issue / reason why I'm not getting any data back from that call is that there is a data mismatch.</p>
<p>Do I need to add the other columns that are listed in the model in the api test?</p>
<p>I've also tested trying to call the /table/Account/3 to load a specific account and it returns no rows... I'm guessing it's a model mismatch but I'm not sure if that's the issue or something else causing it? I'm not seeing any errors or warnings.</p>
<hr>
<p><strong>Update</strong></p>
<p>I figured out what is going on with model first and Azure and how to attach an existing DB in Azure to new code. I'm going to post this here for the hopes that it saves other's time. This really should have been easier to do. I'm not a fan of codefirst (yet) as I like to control the DB by hand... So this makes it a lot easier for me to work with the db backend.</p>
<p>First I created a new project (Azure Mobile App) then under models I right clicked the model and add->new entity data model then added in the azure db name, password and gave it my "user created profile name" as used below. This connection must be edited in the web.config as shown below. </p>
<p>I then had to create the model for the table in DataObjects (without the MS required columns) and create a controller off of the dataobject. I then had to edit the web.config and set a non-entity DB connection string: eg:</p>
<pre><code><add name="[user created preset name]" providerName="System.Data.SqlClient" connectionString="Server=[Azuredb server connection];initial catalog=[DBName];persist security info=True;user id=[user];password=[pass];MultipleActiveResultSets=True"/>
</code></pre>
<p>Finally, in the MobileServiceContext, I had to map the DataObject model to the table in Azure sql and set the connection string to use from the default MS_TableConnectionString to the connectionstring in web.config.</p>
<pre><code> private const string connectionStringName = "Name=[user created preset name]";
</code></pre>
<p>and under OnModelCreating() I added:</p>
<pre><code> modelBuilder.Entity<Account>().ToTable("tblAccount");
</code></pre>
<p>Where Account was the model (class) I created in DataObjects and the tblAccount is the table name in AzureDB.</p> | 2 |

Firebase notification onMessageReceived show the same notification as when app in background | <p>I am sending messages to my app from the Console and I managed to have the app react as I want, when it is in background. So basically there is a notification shown by the SDK and when the user taps it and the app starts, I have some custom data fields to use to build a dialog message. </p>
<p>Since I also want the app to react when on foreground I've added the service and I've noticed that the <code>RemoteMessage</code> also contains a <code>getNotification()</code> method which returns <code>RemoteMessage.Notification</code> which I suppose is used by the SDK to show the notification when app in background.</p>
<p>Is there an easy way to simply use that retrieved notification and display it, just as when the app is in background?</p> | 2 |
Monitor user activity in vb.net | <p>I would like to make a program that monitors user activity. I do not need to know what the user is doing, all i need to know is that he is doing something. Moving the mouse, or typing. The program will be used to show to the company who is at the desk and who is gone from the workstation. So if there is no activity for 2 minutes, that means that the user is away from the computer.</p>
<p>I was thinking of using the keyboard hook and the mouse position to monitor changes every lets say 5 seconds. On every change I will reset the counter.</p>
<p>Is there a better way? (For example reading the screensaver countdown or something like that)</p> | 2 |
align image to a column of text while keeping it responsive | <p>I am trying to code a class schedule in <code>Wordpress</code>. I have attached a picture of a mock up to better illustrate what I am trying to achieve.</p>
<p>Mock Up below here:</p>
<p><a href="https://i.stack.imgur.com/mMNmo.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mMNmo.jpg" alt="enter image description here"></a></p>
<p>The text div keeps either going under the thumb div or wraps around it and my column is lost.</p>
<p>Also, when going into responsive mode, the divs do not align one under each other, but stack up one on top of the other. I am trying to have the thumb image with a column of text next to it just like in the picture and have it scale nicely into small screens.</p>
<p>Any ideas how this could be accomplished? Is it even possible? Thank you so much in advance. </p>
<p>Here is the code:</p>
<pre><code>#text {
width: 33%;
align: left;
clear: both;
}
#thumb {
width: 33%;
align: left;
}
<div id ="thumb"><img src=“---" /></div>

Closing then opening standard input in C under Linux | <p>I have a C console application under Linux (Raspbian - Raspberry Pi). The program has some character animation - it prints out messages character by character. For example, the text </p>
<blockquote>
<p>Please give me your name!</p>
</blockquote>
<p>is printed out completely after 5 seconds (char by char).</p>
<p>Afterwards, the user is asked to type in their name, which works just fine if the user waits for the message to be printed out. However, if the user is impatient and hits the keys on the keyboard randomly, the input request later is compromised.</p>
<p>Imagine the user types in </p>
<blockquote>
<p>abc\nefgh\n</p>
</blockquote>
<p>while the above text is being echoed ('\n' means new line - enter). If that happens, the user will not be asked to properly type in his/her name, but the array of characters 'abc' will be accepted as input and gets validated.</p>
<p>My question is how to disable input (buffering) temorarily (on Linux). I have tried several methods and read numerous posts about doing so, but none of them worked for my purpose.</p>
<p>The function that is responsible for asking for input is as follows:</p>
<pre><code>int getLine(char *s, int length)
{
int i;
char c;
for (i = 0; i < length && (c = getchar()) != EOF && c != '\n'; i++)
{
if (c == '\0')
{
i--;
}
else
{
s[i] = c;
}
}
s[i] = '\0';
while (c != EOF && c != '\n')
{
c = getchar();
}
return i;
}
</code></pre>
<p>Empty lines are eliminated with the help of a while loop in the function calling the one above so enter inputs are considered invalid.</p>
<p>I tried closing stdin, but could not reopen it:</p>
<pre><code>fclose(stdin);
</code></pre>
<p>and emptying buffer before the <code>getLine</code>:</p>
<pre><code>char buf[BUFSIZ];
while (c = fgets(buf, BUFSIZ, stdin) != NULL);
</code></pre>
<p>Unfortunately, it did not work as it does with text files.</p>
<p><code>fflush(stdin);</code> did not work either and is not pretty anyway.</p>
<p>My goal is to prevent users from typing in anything while the text is being written out and to ignore/close input buffering (stdin) temporarily. Also, it would be great to disable outputting (flushing) user inputs during printing as it gets displayed on Linux terminal.</p> | 2 |

Calling function inside angularjs ng-repeat | <p>I am new to angularjs, have creating an phonegap project. In my project I am using WP JSON API User Plus Plugin to fetch data in json format, The API gives the response as few contents, also I need to call another API with parameter get from the previous API. Is it possible to call an API inside an ng-repeat to load different datas.</p>
<p>I am getting data's in json, and load the data in ng-repeat,
I have tried like this</p>
<pre><code><tr ng-repeat="app in multipleApps" ng-init="getActivationDate(app)">
<td><h4> {{ app.Name }} </h4></td>
<td> <img src="{{ app.ava_img }}"/> </td>
</tr>
</code></pre>
<p>which call the below function, </p>
<pre><code>$scope.getActivationDate = function(app) {
Service.getActivationDate(app.name)
.then(function(response) {
var date = response.data.image;
$scope.app.ava_img = date;
},
// ...
};
</code></pre>
<p>the output what i am getting is display's the same image for all "app.ava_img", but the response from service is different. please advise regarding the issue but I have no clue how to use it with ng-repeat.</p>

Converting a JSON object to a value list of a particular key in scala (play) | <p>I have a Json object, which is an output of Json.parse, which is of format </p>
<blockquote>
<p>{ "main_data" : [ {"a" : 1, "b" :2} , {"a" : 3, "b" : 4}, {"a" : 5, "b" : 6}]}.</p>
</blockquote>
<p>I want to create a list out of this Json object with the values of all the "a" key. So in the above example it will be [1,3,5]. As I am new to functional programming the first thing came to my mind was to write a For loop and traverse through the Json object to get the list. </p>
<p>But I was wondering is there a Functional/Scala way to do the above, using Map or flatMap ?</p> | 2 |

Owin Authorization denies Roles | <p>I've recently joined a project team and have been tasked with setting up User Roles for the backend of the project.
It uses ASP.NET C# WebApi with Owin.
My issue is, when I assign an attribute to the Controller Method like this:</p>
<pre><code>[Authorize(Roles = "Admin")]
</code></pre>
<p>The response is always Authorization denied for this request.
However if I simply use:</p>
<pre><code>[Authorize]
</code></pre>
<p>It works.
Note that I am logging in with a User that has been assigned the Role of Admin.</p>
<p>I've noticed that this question is similar to: <a href="https://stackoverflow.com/questions/25661623/authorization-roles-webapi-oauth-owin">Authorization roles WebAPI oauth owin</a></p>
<p>However, it seems their code in startup.cs is different somehow, or else I'm struggling to follow the answer correctly.</p>
<p>The code in the startup.cs that I have to work with is:</p>
<pre><code>public void Configuration(IAppBuilder app)
{
// configure OAuth
ConfigureOAuth(app);
// configure Mvc
HttpConfiguration config = new HttpConfiguration();
WebApiConfig.Register(config);
app.UseWebApi(config);
}
public void ConfigureOAuth(IAppBuilder app)
{
OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
{
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
Provider = new SimpleAuthorizationServerProvider()
};
// Token Generation
app.UseOAuthAuthorizationServer(OAuthServerOptions);
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
}
</code></pre>
<p>Is there something else I need to add in here to allow for Roles or should it be somewhere else in the code.
I'm not completely familiar with ASP.NET C# MVC or WebApi, any help is severely appreciated.</p> | 2 |
Python - Create dictionary of dictionaries from CSV | <p>I have a CSV with the first column having many duplicate values, and the second column being a predetermined code that maps to a value in the third column, such as this:</p>

1, d, 0

3, a, 04
3, b, 23
3, c, 74
3, d, 50

'2':{'a':'1', 'b':'12', 'c':'82','d':'81'},
... }

dict2[row[1]] = row[2] # adds another key, value to dict2
else:
dict1[row[0]] = {} # creates a new key entry for the new dict1 key
dict2 = {} # creates a new dict2 to start building as the value for the new dict1 key
dict2[row[1]] = row[2] # adds the first key, value pair for dict2

Aligning a text box edge with an image corner | <p>I'm looking for a way of exactly aligning (overlaying) the corner edge of my image with corner and edge of a text box edge (bbox or other)</p>
<p>The code in question is:</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
fig, ax = plt.subplots(1)
ax.imshow(np.random.random((256,256)), cmap=plt.get_cmap("viridis"))
ax.axis("off")
ax.annotate(
s = 'image title',
xy=(0, 0),
xytext=(0, 0),
va='top',
ha='left',
fontsize = 15,
bbox=dict(facecolor='white', alpha=1),
)
plt.show()
</code></pre>
<p><a href="https://i.stack.imgur.com/9c825.png" rel="noreferrer"><img src="https://i.stack.imgur.com/9c825.png" alt="Single image"></a></p>
<p>As you can see, the edges of the text box is outside the image. For the life of me, I cannot find a consistent way of aligning the corner of the text box with the corner of the image. Ideally, I'd like the alignment to be independent of font size and image pixel size, but that might be asking a bit too much.</p>
<p>Finally, I'd like to achieve this with a grid of images, like the second example, below.</p>
<pre><code>import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(8, 8))
images = 4*[np.random.random((256,256))]
gs = gridspec.GridSpec(

ncols=2,
top=1.,
bottom=0.,
right=1.,

ax = plt.subplot(g)
im = ax.imshow(
images[i],

ax.set_xticks([])
ax.set_yticks([])

Ionic 2 - ion-scroll doesn't pick content height | <p>In my app I have a panel which shows/hides on the click of a button. This panel has a max-height of 300px. </p>

Using editorconfig within Git submodules | <p>I have a Web application which has dependency on an external module for JSON schema validation. The Web app has its Git repository, within which the module is included as a Git submodule.</p>
<p>On the Web project, I have <code>editorconfig</code> for syntax standardisation. For this(as I use Sublime text), I use <a href="https://github.com/sindresorhus/editorconfig-sublime" rel="noreferrer">editorconfig-sublime</a>.</p>
<p>The module is maintained by another team, and they have their own coding style. I occasionally contribute to it though. </p>
<p>The issue I'm having is that when I add code within the Web folder, to the module, my coding style clashes with theirs, as I have my own <code>.editorconfig</code> file. They don't currently use <code>editorconfig</code>.</p>
<p>My question is this: </p>
<h3>Is it possible and if yes, advisable to use one <code>.editorconfig</code> in the base Git repository and another <code>.editorconfig</code> in the Git submodule? What is the best practice here?</h3> | 2 |

Alternative to PHP $mysql->fetch_assoc()? | <p>So basically I have the following loop to iterate database rows:</p>
<pre><code>while($row = $mysql->fetch_assoc())
</code></pre>
<p>But I need to access the rows <strong>before</strong> this loop as well. So, I do this:</p>
<pre><code>$inside = $mysql->fetch_assoc()
</code></pre>
<p>and <strong>$mysql</strong> <em>loses</em> its rows. When it gets to the while loop it simply does not enter it as the condition becomes NULL.</p>
<p>I tried the following</p>
<pre><code>while($row = $inside)
</code></pre>
<p>but this just waits until timeout (loops indefinitely).</p>
<p>Any idea on how I could perform this, making up for the requirements above? Thank you very much for your help...</p> | 2 |
Zillow and Google Script | <p>I have a script that pulls data from Zillow into a google doc....see below. It has worked fine for a couple of years but recently stopped working.

Jenkins external-monitor-job setup | <p>I'm novice to Jenkins. I want to make Jenkins to monitor my crons. I'm following the official tutorial:
<a href="https://wiki.jenkins-ci.org/display/JENKINS/Monitoring+external+jobs" rel="nofollow">https://wiki.jenkins-ci.org/display/JENKINS/Monitoring+external+jobs</a></p>
<p>Jenkins is running on AWS Ubuntu 14. The installation was fine and I can access Jenkins on 9091.
<a href="http://www.example.com:9091/" rel="nofollow">http://www.example.com:9091/</a></p>
<p>External Monitor Job Plugin was installed by default. It can be found in the Plugin Manager.</p>
<p>What I did so far.
On Jenkins I created new External job called "backup". <a href="http://www.example.com:9091/job/backup/" rel="nofollow">http://www.example.com:9091/job/backup/</a> and basically that's all there.</p>
<p>In my cron file: "/var/spool/cron/crontabs/root":</p>

<p>Because of the <code>mailto</code> settings initially I was receiving <code>no jenkins-core-*.jar found error</code>. I started looking for <code>jenkins-core-*.jar</code> but I didn't find one. In my "/usr/share/jenkins" folder there was only <code>jenkins.war</code> file. I unzipped the .war file and copied the following files to it's folder:</p>
<pre><code>jenkins-core-*.jar

<p>As expected there is noting on the Jenkins side. Obviously I'm missing something. I tryed to remove quotes around <code>"backup"</code> and to change the command <code>backup.sh 2>&1 > /dev/null</code> with something I'm sure is working. For example: <code>cd /my/directory && program myfile.file</code> but this is all. I'm wondering if I have to unzip the whole .war file somewhere or if I need to follow different path? I'm not sure what the error means. I found suggestion it's messing up with Tomcat. Please for some help with this.</p> | 2 |

How to avoid to broadcast a large lookup table in Spark | <p>Can you help me to avoid broadcasting of a large lookup table? I have a table with measurements:</p>
<pre><code>Measurement Value
x1 5.1
x2 8.9
x1 9.1
x3 4.4
x2 2.1
...
</code></pre>
<p>And a list of pairs:</p>
<pre><code>P1 P2
x1 x2
x2 x3
...
</code></pre>
<p>The task is to get all values for both elements of every pair and put them into a magic function. That's how I solved it by broadcasting the large table with the measurements.</p>
<pre class="lang-scala prettyprint-override"><code>case class Measurement(measurement: String, value: Double)
case class Candidate(c1: String, c2: String)
val measurements = Seq(Measurement("x1", 5.1), Measurement("x2", 8.9),
Measurement("x1", 9.1), Measurement("x3", 4.4))
val candidates = Seq(Candidate("x1", "x2"), Candidate("x2", "x3"))
// create data frames
val dfm = sqc.createDataFrame(measurements)
val dfc = sqc.createDataFrame(candidates)
// broadcast lookup table
val lookup = sc.broadcast(dfm.rdd.map(r => (r(0), r(1))).collect())
// udf: run magic test with every candidate
val magic: ((String, String) => Double) = (c1: String, c2: String) => {
val lt = lookup.value
val c1v = lt.filter(_._1 == c1).map(_._2).map(_.asInstanceOf[Double])
val c2v = lt.filter(_._1 == c2).map(_._2).map(_.asInstanceOf[Double])
new Foo().magic(c1v, c2v)
}
val sq1 = udf(magic)
val dfks = dfc.withColumn("magic", sq1(col("c1"), col("c2")))
</code></pre>
<p>As you can guess I'm not pretty happy with the solution. For every pair I filter the lookup table twice, this isn't fast nor elegant. I'm using Spark 1.6.1.</p> | 2 |
Android Google Sheets API V4 - Update public sheet without OAuth | <p>I'm trying to programmatically update a public spreadsheet (set to anyone can edit) via the API but it fails with </p>

credential.createScoped(Collections.singleton(SheetsScopes.SPREADSHEETS));

Data URI default charset | <p>Is there a default charset for data URIs? I read <a href="https://www.rfc-editor.org/rfc/rfc2397" rel="nofollow noreferrer">the spec</a> but I don't see one.</p>
<p>For instance, if I have a data URI for a source map which I expect to be reliably interpreted across browsers, is it OK to omit the charset?</p>
<pre><code>//@ sourceMappingURL=data:application/json;base64,eyJ2ZXJza...
</code></pre>
<p>vs</p>
<pre><code>//@ sourceMappingURL=data:application/json;charset=utf-8;base64,eyJ2ZXJza...
</code></pre>
<p>I see in <a href="https://github.com/substack/node-browserify/issues/753" rel="nofollow noreferrer">this GitHub issue</a> that people have had problems using Chinese characters in source-mapped files without an explicit <code>charset=utf-8</code>. So if there is a default (or, at least, if we could expect browsers to have chosen one), it doesn't seem like <code>utf-8</code> is the one...</p> | 2 |

Div to take entire height of viewport, until scroll to next div | <p>I have 5 div containers. I want to render the first div to be the entire height of the viewport. And on scroll, next div takes over entire height of viewport. How would I do this?</p>

PostgreSQL : Can I retrieve log_min_duration_statement as an integer? | <p>My problem is the following :</p>
<p>I update the setting "log_min_duration_statement" described as an integer in postgreSQL documentation (version 9.5 is used). I use the following query to update it : "<strong>SET log_min_duration_statement to [numberOfMilliseconds]</strong>"</p>
<p>When I try to fetch the updated value I get a duration <strong>string</strong> formatted either in milliseconds (like <strong>"250ms"</strong>) or in seconds (like <strong>"10s"</strong>). I use <strong>"SHOW log_min_duration_statement"</strong> to retrieve the value. I would like to retrieve that value <strong>as an integer representing milliseconds</strong> instead of having it formatted as text with varying units.</p>
<p>Does anyone know about a way to do that ?</p>
<p>Thanks a lot for your time !</p> | 2 |
angular-translate nested JSON and filter | <p>When using <a href="https://angular-translate.github.io/" rel="nofollow noreferrer">angular-translate</a> I can filter my strings like so:</p>
<pre><code><ANY>{{'TRANSLATION_ID' | translate}}</ANY>
</code></pre>
<p>It works very well with the following flat JSON:</p>
<pre><code> {
TRANSLATION_ID: 'A value',
};
</code></pre>
<p>However, I can't figure out how to get it to work using nested translations:</p>
<pre><code><ANY>{{'NAMESPACE.TRANSLATION_ID' | translate}}</ANY>
</code></pre>
<p>And the nested JSON:</p>
<pre><code>{
"NAMESPACE": {
"TRANSLATION_ID": "A value"
}
};
</code></pre>
<p>I am successfully loading the translation using <code>$translateProvider.useStaticFilesLoader({prefix: 'i18n/locale-', suffix: '.json'});</code>, and I make use of other functions of the provider such as <code>$translateProvider.addInterpolation('$translateMessageFormatInterpolation');</code>.</p>
<p>The <a href="https://angular-translate.github.io/docs/#/guide" rel="nofollow noreferrer">documentation</a> shows examples of nested translation using the <a href="https://angular-translate.github.io/docs/#/guide/03_using-translate-service" rel="nofollow noreferrer">service</a> directly, but not the <a href="https://angular-translate.github.io/docs/#/guide/04_using-translate-filter" rel="nofollow noreferrer">filter</a>.</p>
<p><a href="https://stackoverflow.com/questions/33537395/angular-translate-using-usestaticfilesloader-to-load-nested-json">I found a possibly related issue here</a>.
First of all, using the code in the JSFifddle breaks the <code>$translateProvider</code> functions (I got it somehow fixed by extending the replacing variable like so: <code>$TranslateProvider = angular.extend(m, $TranslateProvider);</code> after injecting <code>$translateProvider</code> as <code>m</code> and add <code>pascalprecht.translate</code> as a module dependency, and add <code>var</code> declarations to be able to <code>'use strict'</code>) - so right off the bat it doesn't seem to be a solid solution.</p>
<p>With that JSFiddle code, I got the <em>directive</em> to work, at least for non-nested cases (which are fine and all, but not what's needed here, so I didn't bother testing the nested cases) but not the filter (which I need working for both nested and non-nested translations).</p>
<p>It seems to me namespaced translations should be a pretty big deal, and therefore should be available for all the 3 translation methods (service, directive and filter).</p>
<p>"service" method is rather limited ($translate service doesn't provide a two-way data binding which means more code to listen to events - <a href="https://angular-translate.github.io/docs/#/guide/03_using-translate-service#using-$translate-service_things-to-keep-in-mind" rel="nofollow noreferrer">see doc</a> - and, well, the fact that loading all the interface's string translation in the app's controller/service seems to be a pretty bad practice ; views/templates are here for that if I'm not mistaken).</p>
<p>Has anyone found a solution to that, or is that angular-translate nested JSON works only for the service?</p> | 2 |
EPPlus and Deleting sheets | <p>So I'm using EPPlus to populate a spreadsheet with data. Under certain conditions a sheet will be intentionally deleted, leaving only one sheet with data. The code runs without errors and runs when all sheets are left in, but when after I delete sheets, save and open the workbook I get a series of warnings and errors. The workbook <em>will</em> open normally after that and my process others seems to work fine. Any thoughts? Is deleting the sheets causing the OOXML to be come invalid, and I'm missing a step? Thanks.</p>

Is there a way to use html buttons to add text or number values to an input field using javascript | <p>Basically I'm trying to make a page that looks and works like a simple calculator. Can I use html buttons that when clicked add a number to the input field, then when another button is clicked, another number is added to the string.<br>
Here is the html I've used to set up the buttons and "text" entry field. The function writeNumbers is where I intended to write the JS code to make this work. Any ideas on how to set up this functionality would be greatly welcomed!</p>
<pre><code><p id=demo><p>
<input id="text" type="text">
<button id="seven" type="button" onclick=writeNumbers()>7</button>
<button id="eight" type="button" onclick=writeNumbers()>8</button>
<button id="nine" type="button" onclick=writeNumbers()>9</button>
<br>
<button id="four" type="button" onclick=writeNumbers()>4</button>
<button id="five" type="button" onclick=writeNumbers()>5</button>
<button id="six" type="button" onclick=writeNumbers()>6</button>
<br>
<button id="one" type="button" onclick=writeNumbers()>1</button>
<button id="two" type="button" onclick=writeNumbers()>2</button>
<button id="three" type="button" onclick=writeNumbers()>3</button>
<br>
<button id="cancel" type="button" onclick=writeNumbers()>C</button>
<button id="zero" type="button" onclick=writeNumbers()>0</button>
<button id="equals" type="button" onclick=writeNumbers()>=</button>
</code></pre>
<p>I was considering using adding text to the text to the "p" element with 'demo' id as below but thought this was impractical</p>
<pre><code>document.getElementById("demo").innerHTML = "7";
</code></pre>
<p>I had also tried using an event listener for the button with a document.write link thing but the number would not be entered into the box. Don't think document.write can be used with input fields. Plus this the code below is not an exact excerpt </p>
<pre><code>document.getElementById("seven").addEventListener("click", document.write("7").);
</code></pre>
<p>Tried using the javascript code in the link below, it seemed ideal and could work if I add to it</p>
<p><a href="https://stackoverflow.com/questions/13941055/add-a-string-of-text-into-an-input-field-when-user-clicks-a-button">add-a-string-of-text-into-an-input-field-when-user-clicks-a-button</a></p>

How to use vbApplicationModal with button and icon values in MsgBox | <p>I'm working on a personal project in VBScript, and I want to use the <code>vbApplicationModal</code> constant, whereby clicking out of the window will cause it to flash, like an error message would. Problem is, I have no idea where to put it in the MsgBox. I have:</p>
<pre><code>X=MsgBox("Your details from this computer are being harvested using an altered malicious build of IBM Watson.", 0+48+4096, "IBM Watson")
</code></pre>
<p>However, I do not know where to put <code>vbApplicationModal</code>, or the alternative value (0). As you can see, I already used the values for icons and buttons rather than their vb codes (0 means there is only 'OK', 48 means there is a yellow triangular <strong><em>!</em></strong>, 4096 means the window is always on top of other windows) because it is shorter. Do I have to use the value as well, or can I mix vb values and codes?</p> | 2 |
SQL - format INT to date and add condition | <p>I have a table with a date column. This column is an INT and contains dates in the format YYYYMMDD (for example 20160713). Now I want to get all rows where these dates are after today. I tried the following:</p>
<pre><code>SELECT ID, startdate, comment
FROM comments
WHERE startdate > getdate
</code></pre>
<p>But that results in to following error:</p>
<blockquote>
<p>Arithmetic overflow error converting expression to data type datetime.</p>
</blockquote>
<p>So I tried it by formatting it to a dd/mm/yyyy format</p>
<pre><code>CONVERT(VARCHAR(10), (convert(date,CONVERT(varchar(10),[startdate],103))),103) > getdate()
</code></pre>
<p>but that results into this error:</p>
<blockquote>
<p>The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.</p>
</blockquote>
<p>Any ideas how to do this?</p> | 2 |

html/css - html website with multiple pages - have one menu that can be called? | <p>MY SERVER IS TOO BASIC TO SUPPORT PHP/JAVASCRIPT, ANY SUGGESTIONS? </p>
<p>I have a HTML website with multiple pages. I am using an identical menu on all pages and when I add a page I have to each page and edit the code.</p>
<p>I am wondering is there a way of adding a menu page that can be called?</p>
<p>I am using CSS/HTML is it possible to do anything to help? I have researched a bit and I think it involves PHP, but can PHP be used in conjuncion with CSS/HTML?</p> | 2 |

Windows Driver: ZwReadFile returns STATUS_INVALID_HANDLE | <p>In learning how to write Windows drivers, I am modifying the <a href="https://github.com/Microsoft/Windows-driver-samples" rel="nofollow">Windows Driver Sample</a> for the AvsCamera.</p>
<p>I want to replace the simulated image with one from a bitmap file. In the <code>Synthesizer.cpp</code> file, I have commented out the calls to <code>SynthesizeBars()</code>, <code>ApplyGradient()</code>, and <code>EncodeNumber()</code> within the <code>Synthesize()</code> method, and replaced them with this code:</p>
<pre><code>KIRQL level = KeGetCurrentIrql();
if( level == PASSIVE_LEVEL ) {
DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_INFO_LEVEL, "Ok to perform file io.");
UNICODE_STRING filename;
OBJECT_ATTRIBUTES fileAttr;
IO_STATUS_BLOCK fhStatus;
HANDLE fh;
NTSTATUS status;
RtlInitUnicodeString(&filename, L"\\SystemRoot\\AvsCameraTest.bmp");
InitializeObjectAttributes(&fileAttr, &filename, OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE, NULL, NULL);
status = ZwOpenFile(&fh, FILE_READ_DATA, &fileAttr, &fhStatus, 0, FILE_RANDOM_ACCESS);
if( NT_SUCCESS(status) ) {
status = ZwReadFile(&fh, NULL, NULL, NULL, &fhStatus, m_Buffer, m_Length, /*&byteOffset*/NULL, NULL);
if( NT_SUCCESS(status) ) {
DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_INFO_LEVEL, "Read bitmap file success.\n");
} else DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_ERROR_LEVEL, "Unable to read bitmap file [0x%x].\n", status);
ZwClose(fh);
} else DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_ERROR_LEVEL, "Unable to open bitmap file [0x%x].\n", status);
} else DbgPrintEx(DPFLTR_IHVDRIVER_ID, DPFLTR_ERROR_LEVEL, "Do not perform file io at IRQ level 0x%x.\n", level);
</code></pre>
<p>This is my first step: I am aware that I'm ignoring the bmp header.</p>
<p>The call to <code>ZwOpenFile()</code> is successful, but <code>ZwReadFile()</code> returns <code>STATUS_INVALID_HANDLE</code>.</p>
<p>I've tried using a <code>LARGE_INTEGER byteOffset</code>, and <code>FILE_SYNCHRONOUS_IO_NONALERT</code> instead of <code>FILE_RANDOM_ACCESS</code>. I've also tried using <code>ZwCreateFile()</code> with <code>GENERIC_READ</code> and <code>FILE_ATTRIBUTE_READONLY</code> parameters.</p>
<p>I have been successful in writing to a file using similar code.</p>
<p>What is the issue with my attempt at acquiring the proper filehandle for reading?</p> | 2 |

Clickable html button counter using php or js | <p>I am very new to php and javascript and I was wondering how I could make a global counter that adds 1 to it every time a user presses a button. The number would stay the same even if someone is on a different computer or refreshes the page. I had this using javascript: </p>
<pre><code><script type="text/javascript">
var clicks = 0
function onClick() {
clicks += 1;
document.getElementById("clicks").innerHTML = clicks;
};
</script>
<button type="button" onClick="onClick()">Click me</button>
<footer>Clicks: <a id="clicks">0</a></footer>
</code></pre>
<p>But when ever someone refreshes the page, it resets the number, and it is not global. I tried making something in php which is:</p>
<pre><code><?php
$clicks = 0
public function clickButton()
{
$clicks = $clicks + 1
}
?>
</code></pre>
<p>but I have no idea what I'm doing and how to call the php function or display the php variable.</p> | 2 |

Android - equivalent of UITableViewCell? | <p>Is there an equivalent of a <code>UITableViewCell</code>for a <code>RecyclerView</code> or (any other recyclable view) in Android ? None of my searches have given me any direction. Some help would be really appreciated.</p>
<p>I understand that a <code>RecyclerView</code> has a position that corresponds to a row in the case of a list. But is this correct, is this the equivalent of <code>UITableViewCell</code> in Android ?</p> | 2 |
Are Twilio video and client Javascript SDK cross-platform? | <p>I wanted to know if I can use Twilio Video or Client JavaScript SDK for both web and mobile development. </p>
<p>I have no background in iOS or Android Development so it would be good if I can just use JavaScript SDK use react native or wrap it in Cordova.</p> | 2 |
How to install and import angular 2 '@angular/router'? | <p>I'm trying to use @angular/router from this <a href="https://angular.io/docs/ts/latest/guide/router.html" rel="nofollow">documentation</a>. I tried to install this module using npm: <code>npm install @angular/router --save</code>
And I tried to import this module:</p>
<pre><code>import { ROUTER_DIRECTIVES } from '@angular/router';
</code></pre>
<p>I get an error "Cannot find module '@angular/router'"
I looked at node_modules/@angular/router directory. It has 2 directories: angular1 and angular2. Should I import this module using:</p>
<pre><code>import { ROUTER_DIRECTIVES } from '@angular/router/angular2/router.js';
</code></pre>
<p>Or this is incorrect module? It has only 3 files in angular2 directory: router.js, router.dev.js, router.min.js</p> | 2 |

Socket.io and Node.Js multiple servers | <p>I'm new to Web Sockets in general, but get the main concept.</p>
<p>I am trying to build a simple multiplayer game and would like to have a server selection where I can run sockets on multiple IPs and it will connect the client through that, to mitigate connections in order to improve performance, this is hypothetical in the case of there being thousands of players at once, but would like some insight into how this would work and if there are any resources I can use to integrate this before hand, in order to prevent extra work at a later date. Is this at all possible, as I understand it Node.Js runs on a server and uses the Socket.io dependencies to create sockets within that, so I can't think of a possible solution to route it through another server unless I had multiple sites running it separately.</p> | 2 |
Less.js aggressively caching imported less files | <p>I'm running Less through JavaScript right now, with <code>less = { env: ‘development’ };</code>, and I have a primary file, called main.less, which houses all my <code>@import</code>, however none of my imported "children" .less files are updating, and appears to just be using the old cached styles. </p>
<p>Put a line of code into main.less, compiles. Remove it and put into nav.less, compiles main.less, and appears to yank nav.less from the cache. Ugh.</p>
<p>I've tried <code>less.refresh();</code>, and even tried <code>localStorage.clear();</code>, but nothing seems to change the outcome. </p>
<p>I feel so defeated by this. </p> | 2 |
Have AND Clause if variable is not null in MySQL Select | <p>Hello I am trying to make an If statement inside SQL Select query, I would like to apply only if variable $department is different than NULL. if the variable is different then Null place <code>P2.department = P1.department</code> as AND Clause. </p>
<p>The query line is as follows: </p>
<pre><code>,(SELECT SUM(P2.fee) FROM cases P2 WHERE
IF('$department' IS NULL, 0, P2.department = P1.department) AND curency = 1) as fee_USD
</code></pre>
<p>In the current situation the query is working but it displays wrong results. My question is this is the best way to include <code>P2.department = P1.department AND</code> inside the query. Any help is welcome. </p>
<p>Here is the full query: </p>
<pre><code> SELECT
P1.id
,P1.department
,P1.curency
,P1.fee
,count(P1.id) as count_cases
,(SELECT SUM(P2.fee) FROM cases P2 WHERE
IF('$department' IS NULL, 0, P2.department = P1.department)
AND curency = 1) as fee_USD
FROM cases P1 WHERE 1";
if (!empty($department)) { $sql .= " AND P1.department = '$department'"; }
if (!empty($status)) { $sql .= " AND P1.status = '$status'"; }

Calculate number of days excluding sunday in Hive | <p>I have two timestamps as input. I want to calculate the time difference in hours between those timestamps excluding Sundays.</p>
<p>I can get the number of days using <strong><em>datediff</em></strong> function in hive.</p>
<p>I can get the day of a particular date using <strong><em>from_unixtime(unix_timestamp(startdate), 'EEEE').</em></strong></p>
<p>But I dont know how to relate those functions to achieve my requirement or is there any other easy way to achieve this.</p>
<p>Thanks in Advance.</p> | 2 |
Workaround for NoSuchAlgorithmException not working | <p>I'm getting the following exception when I enable SSL debug via <em>-Djavax.net.debug=ssl</em>:</p>
<pre><code>java.security.NoSuchAlgorithmException: EC AlgorithmParameters not available
</code></pre>
<p>I'm running Centos 6.7, Open JDK 1.8.0_91 & Tomcat 7.0.63</p>
<p>My research indicates that this is a known bug: <a href="https://bugs.centos.org/view.php?id=9482" rel="nofollow noreferrer">https://bugs.centos.org/view.php?id=9482</a></p>
<p>I found numerous sources indicating that a workaround for this is to disable the Elliptic Curve cipher algorithms by setting the following property in the <em>jre/lib/security/java.security</em> file:</p>
<pre><code>jdk.tls.disabledAlgorithms=EC,ECDHE,ECDH
</code></pre>
<p>I looked at my <em>java.security</em> file and found that these algorithms were already disabled:</p>
<pre><code>jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keysize < 768, EC, ECDHE, ECDH
</code></pre>
<p>I tried changing this property to be exactly as shown in the examples I found and that did not work either. I also tried removing the <em>jre/lib/ext/sunec.jar</em> file, which again had no effect.</p>
<p>I've carefully traced my installation of Tomcat to ensure that the <em>jre/lib/security/java.security</em> file I'm modifying is the one Tomcat is running on.</p>
<p>If anyone has any ideas about what is going on here or how I can work around this problem I would be very grateful to get your input.</p>
<p>This question is related to <a href="https://stackoverflow.com/questions/28999410">OpenJDK on OpenShift: "NoSuchAlgorithmException: EC AlgorithmParameters not available"</a> except I'm not using OpenShift and I am able to edit my <em>java.security</em> file to attempt the <em>well known</em> workaround. My problem is that the workaround does not work for me.</p> | 2 |

Python, Find the drive letter with windows installed | <p>I started making a program for fun when I encountered a problem. The problem was that I wanted to find the drive letter with windows installed on it (root drive). I assumed there was a function already made for that but I searched for a while and could not find one. </p>
<p>I wrote this code to do what I just described. Is this code redundant and am I being an idiot? There is probably a much easier way...</p>
<pre><code>def root():
root = ""
i = 0
drives = win32api.GetLogicalDriveStrings()
drives = drives.split("\000")[:-1]
for i in range(0, len(drives)):
drives[i] = drives[i].replace("\\", "/")
i = 0
for i in range(0, len(drives)):
if os.path.exists(drives[i] + "Windows"):
root = drives[i]
break
return root

Mysql syntax error with stored procedure (workbench) | <p>Ok so this is my current code</p>
<pre><code>delimiter //
Create procedure addFish(in_color varchar(45), in_pattern varchar(45))
BEGIN
INSERT INTO ZenFish
(`ZenColorsID`,`Pattern`, `Hatched` )
VALUES
(
(select idZenColors from ZenColors where ColorName = in_color),
in_pattern,
CURRENT_TIMESTAMP()
);
END
delimiter ;
</code></pre>
<p>It does NOTHING when I press run in mysql workbench. Before I added the delimiter marks it at least gave me a syntax error. Adding delimiter lines seems to be what everyone else on stackoverflow was told to do with this problem, so I did it and now... just nothing happens when I press run, or select it all and press run, or run this statement. De nada.</p> | 2 |
