ng-repeat hide a property if its equals DateTime.MinValue | <p>Im trying to <em>hide cells</em> (not the complete row) containg a date that is equal to <code>DateTime.MinValue</code> which is basically <code>0001-01-01T00:00:00</code>.</p>
<p>Here is my view model:</p>
<pre><code>$scope.vm.users = [
{
"Username": "user1",
"EarliestLogin": "0001-01-01T00:00:00",
"LatestLogin": "0001-01-01T00:00:00"
},
{
"Username": "user2",
"EarliestLogin": "2016-07-15T11:18:19Z",
"LatestLogin": "2016-07-15T11:18:19Z"
},
{
"Username": "user3",
"EarliestLogin": "0001-01-01T00:00:00",
"LatestLogin": "0001-01-01T00:00:00"
}
];
</code></pre>
<p>The table looks like that:</p>
<pre><code><table>
<tr>
<th>User Name</th>
<th>Earliest Login</th>
<th>Latest Login</th>
</tr>
<tr ng-repeat="user in vm.users">
<td>{{user.Username}}</td>
<td>{{user.EarliestLogin | date:'short'}}</td>
<td>{{user.LatestLogin | date:'short'}}</td>
</tr>
</table>
</code></pre>
<hr>
<p><strong>Current Output:</strong></p>
<pre><code>User Name Earliest Login Latest Login
user1 1/1/01 12:00 AM 1/1/01 12:00 AM
user2 7/15/16 1:18 PM 7/15/16 1:18 PM
user3 1/1/01 12:00 AM 1/1/01 12:00 AM
</code></pre>
<p><strong>Desired Output:</strong></p>
<pre><code>User Name Earliest Login Latest Login

<p>I was able to hide the complete row using a filter on the <code>ng-repeat</code> but I don't know how to only hide a cell if its <code>DateTime.MinValue</code>...</p>

Set_post_thumbnail not working on Single Page, WordPress | <p>WordPress Codex states usage for 'set_post_thumbnail' is as followed:</p>
<pre><code><?php set_post_thumbnail( $post_id, $thumbnail_id ); ?>
</code></pre>
<p>On the single-page.php I am working in, I have the following code snippets</p>
<pre><code>$post_id = get_the_ID();
// Returns the ID of the current post
</code></pre>
<p>And</p>
<pre><code>$thumb_url2 = mpp_media_src( 'full' );
$thumb_url = $thumb_url2[0];
//Returns the full URL path of first MediaPress image.
</code></pre>
<p>& Lastly I have the following function in my functions.php file.</p>
<pre><code>function get_attachment_id_from_src ($image_src) {
global $wpdb;
$query = "SELECT ID FROM {$wpdb->posts} WHERE guid='$image_src'";
$id = $wpdb->get_var($query);
return $id;
}
</code></pre>
<p>Along with the following back on my single-page</p>
<pre><code>$thumb_id = get_attachment_id_from_src($thumb_url);
</code></pre>
<hr>
<p>A test of </p>
<pre><code>echo $post_id;
</code></pre>
<p>returns </p>
<pre><code>3544
</code></pre>
<p>which is the correct post id number.</p>
<p>A test of </p>
<pre><code>echo $thumb_url;
</code></pre>
<p>returns the image url </p>
<pre><code>http://localhost/mydomain/wp-content/uploads/mediapress/members/374/3535/ATOMS-FOR-PEACE2.jpg
</code></pre>
<p>which is the correct image url.</p>
<p>A test of</p>
<pre><code>echo $thumb_id;
</code></pre>
<p>returns</p>
<pre><code>1627
</code></pre>
<p>Which is the correct thumbnail id.</p>
<hr>
<p>So why, I am wondering, after testing to make sure values in variables are proper and accurate, does inserting the following code seem to have no effect?</p>
<pre><code><?php set_post_thumbnail( $post_id, $thumb_id ); ?>

android locationRequest interval not update as required | <p>in my project , i use GoogleApiClient and locationRequest to get current location and update it periodically after certain interval ,
I know that there is difference between setInterval and
setFastestInterval and </p>
<p>interval is variable that i change from my app settings and has the values of </p>
<p>so I call this :</p>
<pre><code> public int interval = 1 * 1000;
locationRequest.setFastestInterval(interval);
locationRequest.setInterval(interval);
switch (interval_index)
{
case 0:
interval = 1 * 1000;
break;
case 1:
interval = 1 * 60 * 1000;
break;
case 2:
interval = 5 * 60 * 1000;
break;
case 3:
interval = 10 * 60 * 1000;
break;
case 4:
interval = 30 * 60 * 1000;
break;
}
</code></pre>
<p>if i set interval for example to 30 minutes i get updates after 5 minutes for example , it is not constant time but i get updates randomly so why ?</p> | 2 |

How to speed up writing to an Excel sheet | <p>I am currently using Interop objects to write to an Excel spreadsheet. Using stopwatches, I have found that the following implementation is quite timely. The processes in the <code>foreach</code> loop will usually take around 50 seconds to write around 2000 rows, each with 9 columns.</p>
<p>Is there any way to speed this up?</p>
<pre><code>List<string[]> allEntries = fillStringArrayList();
// Set-up for running Excel
xls = new Excel.Application();
workBooks = xls.Workbooks;
workBook = workBooks.Open(workbookPath);
var workSheet = workBook.Sheets["Sheet1"];
// Insert new entries
foreach (string[] entry in allEntries)
{
// Get the final row in the sheet that is being used
Excel.Range usedRange = workSheet.UsedRange;
int rowCount = usedRange.Rows.Count;
// Format Column A to be type "text"
workSheet.Cells[rowCount + 1, 1].NumberFormat = "@";
workSheet.Cells[rowCount + 1, 1] = entry[0];
workSheet.Cells[rowCount + 1, 2] = entry[1];
workSheet.Cells[rowCount + 1, 3] = entry[2];
workSheet.Cells[rowCount + 1, 4] = entry[3];
workSheet.Cells[rowCount + 1, 5] = entry[4];
workSheet.Cells[rowCount + 1, 6] = entry[5];
workSheet.Cells[rowCount + 1, 7] = entry[6];
workSheet.Cells[rowCount + 1, 8] = entry[7];
workSheet.Cells[rowCount + 1, 9] = entry[8];

website htaccess redirect conflict with wordpress | <p>I'm not too clued up on how htaccess file coding works, but I have got the following htaccess code in my root directory and it is responsible for redirecting from url.html to url.php:</p>
<pre><code>RedirectMatch permanent ^(.*)\.htm(l?)$ $1.php
RewriteEngine on
RewriteRule ^index\.htm$ index.php [NC,R]
</code></pre>
<p>This code is important because all of the file names on the website have been changed over from 'html' to 'php' and I want all bookmarks and links made prior to the change over to remain valid.</p>
<p>The problem is, the above htaccess code seems to prevent the wordpress blog from opening, displaying the message "Too many redirects occurred when trying to open url".</p>
<p>Clearly there is some kind of redirect loop happening, but I cannot for the life of me work out exactly what the problem is.</p>
<p>In my wordpress directory (/blog) the htaccess file contains the usual for wordpress:</p>
<pre><code># BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /blog/index.php [L]
</IfModule>
# END WordPress
</code></pre>
<p>When the above htaccess file is removed, the wordpress index file works fine, but because the wordpress htaccess file writes the rules for the post urls, they no longer work.</p>
<p>To summarise, I think there is a conflict between the two htaccess files (first one in the root directory, second one in the /blog directory) that is creating a redirect loop.</p>
<p>Any ideas as to how I might solve this will be very well received.</p>
<p>Thank you all in anticipation.</p> | 2 |

How to write unit tests for proxy pattern? | <p>Will be thankful for your attention, time and efforts ! <br />
I have the following code</p>
<pre><code>public class Employee
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Role { get; set; }
}
public interface IEmployeeRepository
{
Employee GetEmployee(string firstName, string role);
}
public class EmployeeRepository : IEmployeeRepository
{
public Employee GetEmployee(string firstName, string role)
{
//logic here
return new Employee();
}
}
</code></pre>
<p>Now i want to implement cache for <code>EmployeeRepository</code>.
At first i did it using Proxy design pattern</p>
<pre><code> public class ProxyEmployeeRepository : IEmployeeRepository
{
private EmployeeRepository _employeeRepository = new EmployeeRepository();
private MemoryCache _cache = new MemoryCache("UsualCache");
public Employee GetEmployee(string firstName, string role)
{
//do not cache administrators
if (role == "admin")
{
return _employeeRepository.GetEmployee(firstName, role);
}
else
{
//get from cache at first
//if absent call _employeeRepository.GetEmployee and add to cache
//...
}
}
</code></pre>
<p>But when wanted to write unit tests for this class i couldn't do it(i cannot create mock for _employeeRepository and verify whether it was called or not) <br/>
If i implement cache with Decorator pattern then i would have the following code</p>
<pre><code> public class DecoratorEmployeeRepository : IEmployeeRepository
{
private IEmployeeRepository _employeeRepository;
public DecoratorEmployeeRepository(IEmployeeRepository repository)
{
_employeeRepository = repository;
}
private MemoryCache _cache = new MemoryCache("UsualCache");
public Employee GetEmployee(string firstName, string role)
{
//do not cache administrators
if (role == "admin")
{
return _employeeRepository.GetEmployee(firstName, role);
}
else
{
//get from cache at first
//if absent call _employeeRepository.GetEmployee and add to cache
return null;
}
}
}
</code></pre>
<p>and unit tests for it</p>
<pre><code> [TestClass]
public class EmployeeRepositoryTests
{
[TestMethod]
public void GetEmployeeTest_AdminRole()
{
var innerMock = Substitute.For<IEmployeeRepository>();
var employeeRepository = new DecoratorEmployeeRepository(innerMock);
employeeRepository.GetEmployee("Ihor", "admin");
innerMock.Received().GetEmployee(Arg.Any<string>(), Arg.Any<string>());
}
[TestMethod]
public void GetEmployeeTest_NotAdminRole()
{
var innerMock = Substitute.For<IEmployeeRepository>();
var employeeRepository = new DecoratorEmployeeRepository(innerMock);
employeeRepository.GetEmployee("Ihor", "NotAdmin");
innerMock.DidNotReceive().GetEmployee("Ihor", "NotAdmin");
}

Generic and efficient way to send files from a Controller to remote ApiController in ASP.NET MVC | <p>I am working on a multi-level ASP.NET MVC web platform and I have the requirement to send a file from a <code>System.Web.Mvc.Controller</code> to an ASP.NET MVC web-service's <code>System.Web.Http.ApiController</code>, running remotely on a different machine.</p>
<p>Currently, I have this in my <code>Mvc.Controller</code>:</p>
<pre><code>public ActionResult ForwardThisFile(HttpPostedFileBase file)
{
// TODO: Forward file to remote DocumentApi:
DocumentApi.DocumentApiClient client = new DocumentApi.DocumentApiClient();
client.StoreDocument(file /* <-- How-To? */);
return View();
}
</code></pre>
<p>where the <code>DocumentApiClient</code> has been generated via Visual Studio's <em>Add REST API Client...</em> function from a Swagger Url. (The generated client internally uses the <code>Microsoft.Rest.ClientRuntime</code> which is relying on <code>System.Net.Http.HttpClient</code>, <code>HttpRequestMessage</code>, etc.)</p>
<p>The question is, how do I define and implement the DocumentApi to transfer files to it in an efficient and generic way in the <code>ApiController</code>. Currently, I am thinking of three different options:</p>
<ul>
<li><code>[HttpPut] public async Task<IHttpActionResult> StoreDocument(HttpPostedFileBase file)</code></li>
<li><code>[HttpPut] public async Task<IHttpActionResult> StoreDocument(byte[] fileContents, string contentType, string fileName)</code></li>
<li><code>[HttpPut] public async Task<IHttpActionResult> StoreDocument(Stream fileStream, string contentType, string fileName)</code></li>
</ul>
<p>I was thinking, that maybe I could just forward the <code>HttpPostedFileBase</code> instance from the <code>Mvc.Controller</code> to the <code>ApiController</code>, so I've tried the first option. However, <em>Add REST API Client...</em> creates a <code>DocumentApi.Models.HttpPostedFileBase</code> model class in that case and is NOT of the original type <code>System.Web.HttpPostedFileBase</code>. Now, I'm not sure what I should do...</p>
<pre><code>new DocumentApi.Models.HttpPostedFileBase() {
InputStream = file.InputStream,
ContentType = file.ContentType,
ContentLength = file.ContentLength,
FileName = file.FileName,
}
</code></pre>
<p>^ that doesn't work, because for the <code>InputStream</code>, it creates a <code>DocumentApi.Models.Stream</code> class and I have no idea how to convert the <code>System.IO.Stream</code> from the <code>file</code> parameter into a <code>DocumentApi.Models.Stream</code>.</p>
<p>Is it even possible to send a stream across ASP.NET MVC webservices? (Which would basically be the answer to option 3)</p>
<p>In my current state of knowledge, the only alternative appears to me being option 2, where I would send a byte-array containing the whole file. I am asking myself, however, if there is any more convenient or more efficient way to send a file from a <code>Mvc.Controller</code> to a remote <code>ApiController</code>. Is there?<br>
Which one of the options would work and which one is the way to go?</p>
<p>Additionally, I have a <strong>bonus question</strong> to the above regarding <code>HttpPostedFileBase</code>: Is the way via <code>HttpPostedFileBase</code> the most efficient way to handle uploaded files in ASP.NET MVC? I have seen various alternatives:</p>
<ul>
<li><code>HttpPostedFileBase</code> like shown above in the first code sample</li>
<li>Using the raw HTTP-request via <code>Request.Content.ReadAsStreamAsync()</code> or something similar. Maybe the stream is more efficient for my use case?</li>
<li>Using JavaScript to encode a file into a Base64 string and send it via a hidden input field to the controller. (via <code>FileReader</code>'s method <code>readAsDataURL(file)</code>)</li>
</ul>
<p>So many options... Which one is best/most generic/most efficient?</p> | 2 |
Excel UDF to find first and last cell in range with a given value - runs slowly | <p>I'm writing a function which takes a column range and finds the first and last cell in that column which have a certain value. This gives a first row number and a last row number that are then used to return the corresponding subrange in another column.<br>
The idea is that with this function I can apply Excel functions to a (continuous) subsection of a range. E.g. suppose I have a table with various prices of Apples and Bananas, grouped so that all prices of Apples come first, then Bananas. I want to find the minimum price of Apples and the minimum of Bananas, but selecting the whole range and without changing the range over which to minimise. I would use my desired function to feed a range to Excel's MIN function which included just Apples, or just Bananas, without having to manually select these subranges. A MINIF, if you will - like a weak version of SUMIF but for MIN (and potentially many other functions).<br>
I've found a way of doing it but it's running really quite slow. I think it may have to do with the for loop, but I don't understand enough about efficiency in Excel/VBA to know how to improve it. I'm using this code on an Excel table, so the columns I pass are named columns of a table object. I'm using Excel 2010 on Windows 7 Enterprise.</p>
<p>Grateful for any help. Even solutions on how to conditionally apply functions to ranges that deviate radically from this are well received.</p>
<p>Code:</p>
<pre><code>' ParentRange and CriterionRange are columns of the same table.
'I want to extract a reference to the part of ParentRange which corresponds
'by rows to the part of CriterionRange that contains cells with a certain value.
Function CorrespondingSubrange(CriterionRange As Range, Criterion As _
String, ParentRange As Range) As Range
Application.ScreenUpdating = False
Dim RowCounter As Integer
Dim SubRangeFirstRow As Integer
Dim SubRangeFirstCell As Range
Dim SubRangeLastRow As Integer
Dim SubRangeLastCell As Range
Dim RangeCountStarted As Boolean
RangeCountStarted = False
Set SubRangeFirstCell = CriterionRange.Find(What:=Criterion, LookIn:=xlValues, _
LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False)
If Not (SubRangeFirstCell Is Nothing) Then
RangeCountStarted = True
SubRangeFirstRow = SubRangeFirstCell.Row - CriterionRange.Range("A1").Row + 1
For RowCounter = SubRangeFirstRow To CriterionRange.Cells.Count
If Not (CriterionRange.Cells(RowCounter, 1).Value = Criterion) Then
SubRangeLastRow = RowCounter - 1
Exit For
End If
Next
End If
If RangeCountStarted = True And SubRangeLastRow = 0 Then SubRangeLastRow = RowCounter
Set CorrespondingSubrange = ParentRange.Range("A" & SubRangeFirstRow & ":A" & SubRangeLastRow)
Application.ScreenUpdating = True
End Function

<p>I am doing a post order traversal of the binary search tree.
my logic works when the nodes appears in consecutive order, but if the node is not in consecutive order; the frequency of the node is reset.</p>
<p>my time is O(n) and space is O(1).</p>
<p>the issue is when the Nodes do not linked in succession.</p>
<p>my sample Tree:</p>
<pre><code>int main()
{
TreeNode *root = new TreeNode(6);
root->right = new TreeNode(8);
root->right->left = new TreeNode(7);
root->right->right = new TreeNode(8);
root->right->right->right = new TreeNode(8);
root->right->right->right->right = new TreeNode(9);
root->right->right->right->right->left = new TreeNode(8);
root->left = new TreeNode(4);
root->left->right = new TreeNode(5);
root->left->right->right = new TreeNode(5);
root->left->right->right->right = new TreeNode(5);
root->left->left = new TreeNode(1);
root->left->left->right = new TreeNode(1);
root->left->left->right->right = new TreeNode(1);
root->left->left->right->right = new TreeNode(2);
root->left->left->left = new TreeNode(0);
struct holder freq;
int ran = frequencyOfNode(root, &freq);
std::cout << "random" << ran << std::endl;
std::cout << "The Node: " << freq.most->val << " frequency " << freq.count
<< std::endl;
return 0;
}

<p>I'm really confused on how to take into account, when the nodes are not consecutive( i.e 8->8->8->9->8).</p> | 2 |
Tensorflow conv3d_transpose *** Error in 'python': free(): invalid pointer | <p><strong>EDIT</strong> opened issue: <a href="https://github.com/tensorflow/tensorflow/issues/3128" rel="nofollow">https://github.com/tensorflow/tensorflow/issues/3128</a></p>
<p>I'm trying to use the newly added <code>conv3d_transpose</code> created <a href="https://github.com/tensorflow/tensorflow/pull/3049" rel="nofollow">here</a></p>
<p>But I'm getting the error in the title: <code>*** Error in 'python': free(): invalid pointer</code></p>
<p>I have the network working in 2D (using the same data), but it won't run in 3D. </p>
<p>I have tried on two different linux machines both running Ubuntu 14.04. I am currently trying to get it to run on my Mac, but I can't find a build with with the <code>conv3d_transpose</code> included. I had to install the nightly build on my linux machine, but the nightly build for OSX doesn't include it. Does anyone know where I could find it?</p>
<p>The way I input the 3D data may be the cause. My data inputs in 2D images, and I essentially concatenate them into a 3D matrix. For testing purposes, I'm keeping my data set small. My batch size is 1 and my depth is 5. I pull in <code>n_depth * batch_size</code> from my data class, and then reshape it into <code>[batch_size, n_depth, x, y, n_classes]</code></p>
<p>The network itself builds, and it doesn't throw any dimension errors. The error occurs on the first training session. </p>

<p>However this works: "SELECT * FROM Win32_DiskQuota".</p>
<p>According to MSDN:</p>
<blockquote>
<p>For most uses of class descriptors in a WHERE clause, WMI flags the
query as invalid and returns an error. However, use the dot (.)

following query is valid if Prop is a valid property of MyClass and is
type object:</p>
<p>SELECT * FROM MyClass WHERE Prop.embedprop = 5</p>

How to install phpMailer on azure Web App | <p>I've been researching lots of solutions in mail services for azure and I decided that the best solution for me is with phpMailer. I already tried to use the sendgrid API but I want to utilize the Ajax post method with jquery/javascript.</p>
<p>I have also found another solution that involves CURL. But the I'm getting an error on </p>
<pre><code>Dotenv::load(__DIR__);

Postgres - Cascade delete not working | <p>I have a table called "Reviews" and it references a record in a table "ReviewSetups". When I delete a ReviewSetup I was to also delete all child Reviews (so cascade delete).</p>
<p>I have setup the foreign key like below on the Reviews table but nothing gets deleted when I delete a parent ReviewSetup.</p>
<p>I have other entities in by db as well which I migrated with a FK in exactly the same way and those work fine.</p>

Installing Minecraft server from .exe instead of .jar | <p>Very new to minecraft, and I'm trying to install server 1.8 (protocol number 42)..</p>
<p>Not sure if the .jar file (mcversions.net) is the normal way to install, but can't get it to work - either double clicking or using </p>
<pre><code> java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui'
</code></pre>
<p>Minecraft 1.8 (client game) works on the same computer so I don't think it's a java versioning issue.</p>
<p>Is there an executable of the 1.8 server that can be used instead? If not, would installing the latest version using the .exe and replacing the .jar with 1.8 work?</p> | 2 |
Python Django - print within a loop, inside view function | <p>I'm trying to find a way to print within a loop, inside a view function.</p>
<p>I want to do something like this: </p>
<pre><code>def some_page(request):
for i in range(1, 5):
print("<span>current index: %s</span>") % (i)
</code></pre>
<p>But I need to use HttpResponse, (or render, but from what I learned until now, HttpResponse is for small things, like this)</p>
<p>so I need to do</p>
<pre><code>return HttpResponse("<span>current...")
</code></pre>
<p>Which will not works - because <code>return</code> will end the function.</p>
<p>So how can i do function that will prints within loop ? (like the example above)</p>
<p>*With Python, not in the template (not Jinja)</p>
<p>Thanks in advance.</p> | 2 |

InputStream closed unexpectedly while using Jersey MultiPart file upload & Server-Sent Events (SSE) | <p>I'm using Jersey Multipart for uploading file to the server via Rest API. In the resource method, I accessed the file content via InputStream. I want to return the uploaded file size to the client with <a href="https://jersey.java.net/apidocs/2.23.1/jersey/org/glassfish/jersey/media/sse/EventOutput.html" rel="nofollow">EventOutput</a> using <a href="https://jersey.java.net/documentation/latest/sse.html#overview" rel="nofollow">SSE</a> so the client easily get the uploaded file size directly from upload resource method.
I'm using Jersey as JAX-RS implementation in java with Grizzly Http server. Here is my code:</p>
<pre><code>@POST
@Path("upload")
@Produces(SseFeature.SERVER_SENT_EVENTS)
@Consumes("multipart/form-data;charset=utf-8")
public EventOutput upload(@FormDataParam("file") InputStream file,
@FormDataParam("file") FormDataContentDisposition fileDisposition) {
final EventOutput eventOutput = new EventOutput();
try {
new Thread(new Runnable() {
@Override
public void run() {
try {
int read = -1;
byte[] buffer = new byte[1024];
OutboundEvent.Builder eventBuilder
= new OutboundEvent.Builder();
OutboundEvent event = null;
long totalRead = 0, lastReadMB = 0;
while ((read = file.read(buffer)) != -1) {
totalRead += read;
if (lastReadMB != (totalRead / (1024 * 1024))) {
lastReadMB = totalRead / (1024 * 1024);
event = eventBuilder.name("uploaded").data(Long.class, totalRead).build();
eventOutput.write(event);
}
}
event = eventBuilder.name("uploaded").data(Long.class, totalRead).build();
eventOutput.write(event);
} catch (Exception e) {
throw new RuntimeException(
"Error when writing the event.", e);
} finally {
try {
eventOutput.close();
} catch (Exception ioClose) {
throw new RuntimeException(
"Error when closing the event output.", ioClose);
}
}
}
}).start();
return eventOutput;
} catch (Exception e) {
logger.error(e.toString(), e);
}
throw new WebApplicationException(Response.status(Response.Status.INTERNAL_SERVER_ERROR).
entity("something happened").build());
}
</code></pre>
<p>
The problem is when my resource method return EventOutput as a response and request processing thread back to the I/O container, the InputStream closed and the processing thread can't access to the uploaded file. Here is the exception:</p>

<p><br/>
1- What's the problem in the code? Why InputStream is closed in the middle of the file transfer?<br/><br/>
2- Is there any alternative way to return the uploaded file size to the client in server side? (REQUIREMENT: the upload resource method must handle upload file asynchronously in different thread)</p> | 2 |

Observe progress of UIView.animateWithDuration/CABasicAnimation? | <p>Is there a way to observe the "time progress" of UIView.animateWithDuration...family of methods from UIView /alternatively CA animations?</p>
<p>I am animating a view's frame and I need to be informed how it is progressing.
My line of thinking was I can either </p>
<p>1) tap into CAAnimation related stuff or </p>
<p>2) observe the animated properties (like frame) and do my own calculations each screen frame.</p>
<p>Approach 1) turns out to be a dead end, inspecting the internal of how CAAnimations work told me absolutely nothing...and 2) is flawed as the "model layer tree is updated immediately and tapping into the presentation tree is difficult as the presentation layer is nil when you start. </p>
<p>I am pretty desperate, I was thinking that hooking into CADisplayLink will give me a tick and then I simply check something that is affected by the animation but there is nothing to tap to.
Do you think going the NSTimer way that is launched in the same scope as the animation method is ok? If I know animation duration then I can generate the progress myself.</p> | 2 |

Ubuntu default port permissions | <p>I am trying to communicate with an external GPS device using UART on a Raspberry Pi, but I am having some issues with the default permissions on the serial port.</p>
<pre><code> ubuntu@ubuntu:~$ ls -la /dev/ttyS0
crw--w---- 1 root tty 4, 64 Jul 2 17:43 /dev/ttyS0
</code></pre>
<p>As you can see, the group 'tty' only has permission to write to the port, not read. This then leads to 'permission denied' messages when I try to read from the port in Python. I have been working around the problem for now using:</p>
<pre><code> sudo chmod g+r /dev/ttyS0
</code></pre>
<p>But this wont work forever, as the goal is for this port to be used automatically after startup.</p>
<p>Is there a way to change the default permissions so that the group 'tty' always has read access?</p>

<p>The command would check if the system is not <strong>32-Bit</strong> Processor then the operation is going to be in <strong>C:\Program Files (x86)</strong> instead of <strong>C:\Program Files</strong>. and if the it is <strong>32-Bit</strong> not <strong>64-Bit</strong> then it would perform the operation in <strong>C:\Program Files</strong>.</p>

jQuery slideUp on Table Row and remove | <p>I'm having trouble with the following code. I'm trying to remove a specific row from a table using jQuery, but I'd like to use the slideUp effect so the row slides up and then removes itself. I've tried the following, but it does not seem to respect the effect. It just removes itself.</p>
<pre><code>$('[data-company-id='+companyId+']').closest('tr').slideUp('fast', function() { $(this).remove(); });
</code></pre>
<p>My table row contains a button in one of the cells with a data-company-id attribute. This does work in getting the right cell, and corresponding parent and remove it. But it does not slide Up before the remove.</p>
<p>What am I doing wrong?</p> | 2 |
AudioSource in Unity3D does not play WAV file | <p>I am updating an AudioSource in Unity3D during runtime when I click.</p>
<p>I created a Cube game object. </p>
<p>When I click the cube I send properties to my AudioSource. </p>
<p><strong>NOTE:</strong> this is to eventually play many other wav files that are passed in via a string array of pipe delimited wav files (which exist in the Assets Audio folder). </p>
<p>So I need to update the AudioSource with each CLICK EVENT whereby each time it will load a new file selected from the array.</p>
<p>Okay, the Unity3D Editor shows my public variables from the script, and it fills them out at runtime (upon clicking the cube.)</p>
<p>My <strong>path</strong> variable shows up perfectly in the Unity3D editor.</p>
<p>But the problem is although the <strong>Audio Clip</strong> <em>property</em> in the editor shows the small orange audio logo (as if something is there/loaded), the name of the file that I grabbed from my Assets/Audio folder is always empty.</p>
<p>Nothing plays, but I get <strong>no errors</strong>!</p>
<p>And the properties <em>playOnAwake</em>, <em>volume</em>, <em>etc</em>. all show me exactly what I express them to do via my script.</p>
<p><strong>NOTE:</strong> In the first image, the <strong>path</strong> <em>variable</em> correctly points to the .wav file.</p>
<p>Why is my .wav not playing? </p>
<p>Why is the .wav filename not appearing in the <strong>Audio Clip</strong> text box area?</p>

<p>I could not try and import 1.8 which is supposedly already present on my computer. </p>
<p>A step by step approach of how to import the newer version of JDK will be appreciated. </p>

How to make a RecyclerView adapter to get 3 items of an arraylist in every row | <p>I need some help with a RecyclerView.Adapter. I pass to a recyclerview adapter an arraylist of object Dart, I have an simple_list_item.xml where it has 3 textviews (dart1Txt, dart2Txt and dart3Txt). I want the adapter to get the values from the arraylist and fill the textviews. For example I have the values 10, 20, 30, 3, 5, 6 and I want to be printed like that</p>
<p>10 20 30</p>
<p>3 5 6</p>
<p>and so on.</p>
<p>I cant understand how to make this. This my onBindViewHolder.</p>
<pre><code>onBindViewHolder(RoundsStatsAdapter.ViewHolder holder, int position){
Dart dart = mDarts.get(position);
holder.dart1Textview.setText(String.valueOf(dart.getScore()));
}
</code></pre>
<p><strong>Update for more info:</strong>
I have a Dart object which has a field dartScore. I sent an arrayList of Dart objects and I want the recyclerview adapter to get the first 3 Darts from the arraylist and fill the 3 textviews with the dartScore, after that take the next 3 Darts from the arraylist and to a new row fill again the 3 textviews and so on.</p>

<p>but how do I set an array element $image and save the multiple values into one field, so when I upload let's say three images, the saved values in the database image field should be like this:

Why does Python's pathlib and os lib return different results for mapped network drives in Windows? | <p>Trying to resolve a path using Python 3 on Windows 10. The path in question is available as a Mapped Network Drive. (This happens to be done through VirtualBox Shared Folders, but I hope that is not relevant here).</p>
<p>The good old <code>os.path.abspath</code> gives me a path that starts with the drive letter that was mapped in Windows. This is exactly what I expected and needed.</p>
<p>But when I try to upgrade to <code>pathlib</code>'s <code>resolve</code> function, I get a different result, in UNC notation. This is not expected, and not useful for my purposes. (Many programs do not accept UNC paths as input, they require a 'local' path.)</p>
<ol>
<li>What is the reason for this difference?</li>
<li>How can one control this behavior so that <code>pathlib</code> can return a drive-letter-based path?</li>
<li>Can anyone point me to documentation of this? I cannot find it in Python's documentation.</li>
</ol>
<p>Demonstration:</p>
<pre><code>PS C:\Users\user> python
Python 3.5.1 (v3.5.1:37a07cee5969, Dec 6 2015, 01:54:25) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> import pathlib
>>> path = 'd:\\asdf'
>>> print(os.path.abspath(path))
d:\asdf
>>> print(pathlib.Path(path).resolve())

Responsive Layout with DIV Percentages | <p>I've have started working on a new PHP based chat system for one of my projects and recently I've been spending a lot of time reading about Responsive layouts, I've decided that I'd like to avoid using bootstrap even so it does offer lots of great features, and I feel there is more to learn in doing things from scratch then using an already established set of code...that being said.</p>
<p>Here is some sample code I put together that is not behaving the way I expected.</p>
<pre><code><!DOCTYPE html>

<p>I noticed that the percentages assigned to inner DIV's don't seem to relate to their parent div as in the case of "message_entry" to the container.</p>
<p>Any thoughts would be much appreciated.</p> | 2 |

Why do I get "DSO missing" error even when the linker can locate the library? | <p>I am compiling a program against a shared library I have written. This library in turn relies on <code>Boost::program_options</code> (among other libraries). When I compile my program, I need of course to mention my library, but I get a DSO error:</p>
<pre><code>g++ ism_create_conf.cc -o ism_create_conf -lglsim_ol -lglsim -lhdf5 -lgsl
/usr/bin/ld.real: /tmp/cc9mBWmM.o: undefined reference to symbol_ZN5boost15program_options8validateERNS_3anyERKSt6vectorISsSaISsEEPSsi'
//usr/lib/x86_64-linux-gnu/libboost_program_options.so.1.55.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
</code></pre>
<p>I know that the error goes away if I add <code>-lboost_program_options</code>. What I don't understand is </p>
<ol>
<li><p>Why do I have to do this even if my program does not call Boost directly (only through my glsim library).</p></li>
<li><p>Why does the linker want <code>-lboost_program_options</code> when it actually found the correct library (and location) by itself (see the second line of the error message).</p></li>
</ol>
<p>The situation is similar to what was asked e.g <a href="https://stackoverflow.com/questions/19901934">here</a>, but I am asking something different: I know the solution is to mention the library in the command line, I want to know <em>why</em> I have to do this <em>even if the linker already knows</em> where the library is. There is obviously something I do not understand about how shared libraries work, it seems to me that when I use other shared libraries, these libraries can automatically call other shared libraries <em>they</em> need. However, the shared library I built does not have this ability.</p> | 2 |
Upload file to server using ionic | <p>I am building a mobile app using ionic. One of the usecase is to let the user browse a file and upload it to the backend server (which exposes a rest service).</p>
<p>On the UI, I am using the html file tag</p>
<pre><code><input type="file" ng-select="uploadFile($files)" multiple>
</code></pre>
<p>This opens a file browser to select a file. Then in the controller, I am doing the following</p>
<pre><code>.controller('UploadDocCtrl', function ($scope, $cordovaFileTransfer) {
$scope.uploadFile = function(files) {
console.log("selected file "+files);
// hard coded file path "/android_asset/www/img/ionic.pdf" to be replaced with the user selected file
$cordovaFileTransfer.upload(restServiceEndpoint, "/android_asset/www/img/ionic.pdf", properties).then(function(result) {
console.log("SUCCESS: " + JSON.stringify(result.response));
}, function(err) {
console.log("ERROR: " + JSON.stringify(err));
}, function (progress) {
// constant progress updates
});
});
</code></pre>
<p>The problem is that I am not able to get a reference to the selected file. Can someone please help with the steps to achieve this. Thanks!</p> | 2 |
Inaccurate line reporting of React JS error | <p>I have been having numerous issues with error reporting in React js. So the actual error will be correct, but the line reported will not be. I'm guessing this is because the JSX is converted into regular Javascript, thus either creating more or less lines of code. This makes it rather difficult to actually track down and fix these errors, when the console is telling me it occurs on line x and line x is a newline or other random code that is obviously not connected to the error. Has anyone else solved this issue?</p>
<p>I am using Google Chrome and I also have the react developer tools installed.</p> | 2 |
Asynchornous SNMP get message with SNMP4J | <p>I have been working in a simple SNMP manager for java using the library SNMP4J. I am trying to send simple asynchronous get messages. I have greated a SNMPmanager to create the PDUs and start the listeners and a simple class named SNMPget that makes a simple get request. </p>
<p>As stated in the <a href="http://www.snmp4j.org/doc/org/snmp4j/package-summary.html" rel="nofollow">javadoc</a>:</p>
<blockquote>
<p>Asynchronous responses are returned by calling a callback method on an object instance that implements the ResponseListener interface. </p>
</blockquote>
<p>I have followed the exact instructions to implement the callback but looks like the callback method onResponse is never executed when sending a get request. In fact, I have used wireshark to check if packets are being send and the request is correctly send and the correct response is received. Any clue on what I am doing wrong?</p>

what does [ -n "$VARIABLE" ] || exit 0 mean | <p>Looking at correcting an issue in /etc/init.d/hostapd on Debian. However, I have no clue what this line of code does nor how it works</p>
<pre><code>[ -n "$DAEMON_CONF" ] || exit 0
</code></pre>
<p>In searching online for bash tutorials, I've never seen anyone do this</p>
<p>When I run the code, my shell window closes (because $DAEMON_CONF is not set to anything). If I change the code to </p>
<pre><code>[ -n "not empty" ] || exit 0
</code></pre>
<p>my console window does not close. </p>
<p>so, -n evaluates to true, and or'ed with exit 0, is what?</p> | 2 |
AngularJS services and promises best practice | <p>I have an AngularJS application where I have <code>service</code>s that calls <code>$http</code> resource and returns a <code>promise</code> that I resolve in my controller. Here's a sample of what I'm doing:</p>
<pre><code>app.service('Blog', function($http, $q) {
var deferred = $q.defer();
$http.get('http://blog.com/sampleblog')
.then(function(res) {
// data massaging stuffs
return deferred.resolve(res.data);
}, function(err) {
// may be some error message checking and beautifying error message
return deferred.reject(err);
});
// chain if further more HTTP calls
return deferred.promise;
});
</code></pre>
<p>But I could simply do the following as well:</p>
<pre><code>app.service('Blog', function($http) {
return $http.get('http://blog.com/sampleblog');
});
</code></pre>
<p>And then do the validation, error beautifying, chaining promises, etc. at the <code>controller</code> level.</p>
<p>My question is : Which is considered as 'best practice', if any, in terms of code resiliency and flexibility? Or is there a better way to do it completely different than this ?</p> | 2 |
Issue with Laravel 5.2 and jenssegers/laravel-mongodb | <p>I am trying to integrate mongodb to an application I am developing with Laravel 5.2. I have mongodb installed on my computer and the php driver working correctly <i>(I have a standalone php file with a very basic connection to my database and the results are brought correctly).</i></p>
<p>As the application will work as a REST API, I created a very basic function that will return all the documents in the collection in the database but I get this error:</p>
<pre><code>ConnectionTimeoutException in Collection.php line 437:
No suitable servers found (`serverselectiontryonce` set): [connection timeout calling ismaster on '127.0.0.1:3306']
</code></pre>
<p>I used both the Eloquent as well as the DB approach but the result is the same. </p>
<p>The code belongs to the Collection.php file inside the <i>vendor/mongodb/mongodb/src/</i> folder and the line contains this:</p>
<pre><code>$server = $this->manager->selectServer($options['readPreference']);
</code></pre>
<p>I'm using <b>Mongo 3.2.7</b> and <b>jenssegers/laravel-mongodb 3.0.x</b>.</p>
<p>My standalone php file and the mongo shell work as they should and when I run <code>pgrep mongod</code> the process id is returned so I know it's working, but I can't get this to work within my Laravel 5.2 application.</p>
<p>Any ideas?</p> | 2 |
use array.prototype.map via call on a string | <p>I know the basic of call and array.prototype.map.call() function takes two arguments, the first one is the object context to be used as this is inside the called function and second is the argument list. But in MDN I found an example where array.prototype.map is used via a call method and a string is passed as the first argument.</p>
<p>I want to know how the passed string gets manipulated inside map function. No this keyword inside map function. How does the map know that it is called on a string?</p>
<pre><code>var map = Array.prototype.map;
var a = map.call('Hello World', function(x) { return x.charCodeAt(0); });

TableView selected cells - checkmarks disappear when scrolled out of sight and new cell checked | <p>I have a tableViewCell that uses a checkmark in <code>accessoryType</code> of cell. I have a function that puts the contents of the cell into textField and similarly removes the text from the text field when it is unchecked.</p>
<p>It seems to work fine but if I check a cell and want to check a cell thats not visible (IOW) I need to scroll the tableView, the cell that was checked (is now not visible) seems to uncheck itself (Only when I check a new visible cell).</p>
<p>The multi select works with visible cells only.</p>
<p>Here is my code:</p>
<pre><code>func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath)
let row = indexPath.row
cell.textLabel?.text = painArea[row]
cell.accessoryType = .None
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
//selectedRow = indexPath
tableView.deselectRowAtIndexPath(indexPath, animated: true)
let row = indexPath.row
let cell = tableView.cellForRowAtIndexPath(indexPath)
if cell!.accessoryType == .Checkmark {
cell!.accessoryType = .None
} else {
cell!.accessoryType = .Checkmark
}
populateDescription()
print(painArea[row])
}
var painDescription = ["very sore"]
func populateDescription() {
painDescription.removeAll()
severityText.text = ""
for cell in tableView.visibleCells {
if cell.accessoryType == .Checkmark {
painDescription.append((cell.textLabel?.text)! + " ")
}
var painArea = ""
var i = 1
while i <= painDescription.count {
painArea += painDescription[i-1] + "~"
i = i + 1
}
severityText.text = painArea
}
</code></pre>
<p>I hope I am explaining myself adequately. I don't want the non visible cells to be unchecked and thus removed from my text field unless I uncheck it.</p>
<p>Any ideas would be most appreciated.</p>
<p>Kind regards</p>

Determine available memory in pure Python | <p>I am aware of the <a href="https://github.com/giampaolo/psutil" rel="nofollow">psutil</a> package which provides (along with many other things) a way to access information about system memory, including the amount of available memory (<code>psutil.virtual_memory().available</code>). How would I go about querying available memory in a pure Python implementation? The solution would need to work for UNIX-like systems, including Linux, OS X, and so on.</p> | 2 |
Codeigniter Load header and footer only once | <p>I'm developing an admin portal using Codeigniter. Here i want to load the header and footer and sidebar only once and change the main content without loading the header and footer everytime.
Please provide some good reference which i can refer. I dont want to go about with the ajax technique since im using angular js I think codeigniter templates will be the right approach but im new to codeigniter templates. So some good links to template tutorials would be preferable.

Does kryo serialization work on non serializable class and class have non serializable attributes? | <p>I'm trying to use Kryo library to convert any given object to byteArray and store in a data store or queue for later use.

Using multiple instances of same user control simultaneously | <p>I am creating an application using wpf and MVVM. I've run into an issue where one of the controls uses three copies of another control at the same time. All three need to have their own instance of the related view model. Currently I have bindings in the user control's view that relate to the view model, but I do not have the control's data context set in its own xaml.</p>
<p>I don't remember where I saw this, but my initial attempt was to use an observable collection like so:
In the model:</p>
<pre><code>private ObservableCollection<SignalStrengthViewModel> signalStrengths;
public GyroViewModel()
{
this.signalStrengths = new ObservableCollection<SignalStrengthViewModel>();
this.signalStrengths.Add(new SignalStrengthViewModel(Color.FromRgb(0, 128, 255)));
this.signalStrengths.Add(new SignalStrengthViewModel(Color.FromRgb(63, 163, 153)));
this.signalStrengths.Add(new SignalStrengthViewModel(Color.FromRgb(121, 132, 196)));
</code></pre>
<p>}</p>
<p>and the xaml of the containing control:</p>
<pre><code><controls:SignalStrengthUserControl x:Name="Link1SignalStrengthControl" DataContext="{Binding SignalStrengths[0], Mode=OneWayToSource}"/>
<controls:SignalStrengthUserControl x:Name="Link2SignalStrengthControl" DataContext="{Binding SignalStrengths[1], Mode=OneWayToSource}"/>
<controls:SignalStrengthUserControl x:Name="Link3SignalStrengthControl" DataContext="{Binding SignalStrengths[2], Mode=OneWayToSource}"/>
</code></pre>
<p>This doesn't seem to actually bind the instances of the control with the instances of the view models. I've also tried moving the list to the code behind containing control's xaml with no change in the result.</p>
<p>Can anyone tell me what I'm doing wrong?</p>
<p>I have seen questions here and elsewhere that use data templates for text boxes, but I haven't found a way to make that work here (and they were all for text boxes).</p>
<p>Some of the other questions I've looked at:</p>

.NET Standard Library vs. .NET Standard | <p>Reading some blogs and the official <a href="https://docs.microsoft.com/en-us/dotnet/articles/standard/library">documentation for .NET Core 1.0</a>, I'm still quite confused (like many others).<br>
Don't get me wrong, I've literally read dozens of posts on the web trying to understand the architecture and terms for this new platform.</p>
<p>Reading the docs and blogs, this is what they say about <strong>.NET Standard Library</strong>:</p>
<blockquote>
<p>The .NET Standard Library is a formal specification of .NET APIs that
are intended to be available on all .NET runtimes.</p>
</blockquote>
<p>But they also use this term: <strong>.NET Standard</strong> and <strong>netstandard</strong> as you can see on the <a href="https://docs.microsoft.com/en-us/dotnet/articles/standard/library#net-platforms-support">Platform Support table</a>.</p>
<p>Question: <strong>.NET Standard Library</strong> <code>==</code> <strong>.NET Standard</strong>? If not, what's difference?</p> | 2 |
Yii 2. Using a model from a string | <p>I have a weird scenario, I am getting the model name as a string, so If I wanted to use it, but how do I manage the import class part? Any ideas?</p>
<p>I have tried:</p>
<pre><code> $model = new $tmpModel;
var_dump($model);
</code></pre>
<p>Now I get: "Class 'Organization' not found", but I have imported the class manually just to test, but still error.</p>
<pre><code>use app\models\Organization;
</code></pre>
<p>Any ideas?</p>
<p><strong>EDIT</strong>: I think I needed some sleep. With help of comments here code looks like these:</p>
<pre><code>$className = "app\models\\".$this->modelSave;
$model = Yii::createObject([
'class' => $className,
]);
var_dump($model);

<Label Background="LightGray" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" >Sample control </Label>
</ContentControl>
</code></pre>
<p>The sample control ( label ) inside the ContentControl works just fine and expands depending on size changes of the ContentControl.</p>
<p>When I now replace the Label with an UserControl the size of the Usercontrol has as maxsize the position of the label which is inside it</p>
<p>Here the UserControl</p>

Heterogenous Layouts inside RecyclerView | <p>I am developing a weather app in which i wanted to use two <code>Views</code> inside <code>RecyclerView</code> which is having <code>CursorAdapter</code> as its member. I want to use one <code>View</code> to display todays weather and other view to display other days weathers. My <code>RecyclerView</code> is working perfectly if I only use one <code>View</code> to display weather. I have also overwritten <code>getItemViewType()? to get to know which</code>View` type I should inflate.</p>
<p>Code for <code>getItemViewType()</code>:</p>
<pre><code>private static int VIEW_TYPE_TODAY = 0;
private static int VIEW_TYPE_FUTURE_DAY = 1;
@Override
public int getItemViewType(int position) {
if(position == VIEW_TYPE_TODAY)
return VIEW_TYPE_TODAY;
else
return VIEW_TYPE_FUTURE_DAY;
}
</code></pre>
<p>Code for the <code>newView()</code> of <code>CursorAdapter</code> which I have overwritten:</p>
<pre><code>@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
int viewType = getItemViewType(cursor.getPosition());
int layoutId = -1;
if(viewType==VIEW_TYPE_TODAY)
layoutId = R.layout.list_item_forecast_today;
else if(viewType==VIEW_TYPE_FUTURE_DAY)
layoutId = R.layout.list_item_forecast;
View view = LayoutInflater.from(context).inflate(layoutId, parent, false);
return view;
}
</code></pre>
<p>No matter what the value of <code>position</code> in <code>getItemViewType()</code> is, the function is always returning <code>VIEW_TYPE_TODAY</code>.</p>
<p>Can some please tell what I am doing wrong? </p> | 2 |
Can you pass multiple glob strings to vscode findFiles api | <p>I would like to ignore folders that have been excluded in the workspace settings when I call the api <code>findFiles</code> (<a href="https://code.visualstudio.com/Docs/extensionAPI/vscode-api#WorkspaceConfiguration" rel="noreferrer">https://code.visualstudio.com/Docs/extensionAPI/vscode-api#WorkspaceConfiguration</a>), however I'm not sure how to do this. I have tried looking for a way to combine glob statements but I haven't had much luck. I've found the GLOB_BRACE examples, but I don't think that will work in this case.</p>
<p>(e.g. glob("{foo/<em>.cpp,bar/</em>.cpp}", GLOB_BRACE))</p>
<p>Is there a way to pass multiple directories to the glob statement in findFiles to ignore?</p>
<p>I ideally would like to do something like this...</p>
<pre><code>let search_config = vscode.workspace.getConfiguration( "search" );
let search_exclude_settings = search_config.get( "exclude" );
let exclude_properties = "{";
for ( var exclude in search_exclude_settings ) {
if( search_exclude_settings.hasOwnProperty( exclude ) ) {
exclude_properties += exclude + ",";
}
}
exclude_properties += filename_and_extension + "}";
var files = vscode.workspace.findFiles(filename_search, exclude_properties, 100);
</code></pre>
<p>but unfortunately that doesn't work. Any ideas would be greatly appreciated! I do apologise if I'm probably missing something blindingly obvious.</p>
<p>Thank you for your time!</p>

Angular upload text file then get content | <p>I'm trying to figure out how to read a text/xml file's content which is uploaded onto my WebApp. At this point I don't want/need to hit the server, I simply want to get the file's content/text.</p>
<p>Here's what I have done so far:
<strong>xmlDiff.html:</strong></p>
<pre><code><div id="xmlDiff-div" class="wrapper">
<div class="configurationView ">
<div class="panelHeader">Upload XML Files</div>
<div class="treeWrapper panelBody">
<button ngf-select="uploadLeftFile($file)" accept="xml/*" ngf-max-height="1000" ngf-max-size="2MB">
Upload Left File</button>
<br><br>
<button ngf-select="uploadRightFile($file)" accept="xml/*" ngf-max-height="1000" ngf-max-size="2MB">
Upload Right File</button>
<br><br>
</div>
</div>
<div id="diff_editors_div">
<div class="panelheader sectionHeader">XML Diff Results</div>
<div id="compare"></div>
</div>
</div>
</code></pre>
<p>Now, here's my controller:</p>
<pre><code>app.controller('XmlDiffCtrl', ['$scope', '$q', '$location', '$timeout', function ($scope, $q, $location, $timeout) {
$('#compare').mergely({
cmsettings: {readOnly: false, lineNumbers: true},
ignorews: true,
width: 'auto',
height: 'auto',
lhs: function (setValue) {
setValue('paste left XML here');
},
rhs: function (setValue) {
setValue('paste right XML here');
}
});
$scope.uploadRightFile = function (file) {
console.log("Upload Right File has been called");
console.log("file content :" + file);
$scope.rightFileText = file.data; **doesn't work, need an alternative**
};
$scope.uploadLeftFile = function (file) {
};
}]);
</code></pre>
<p>Just as a note, I'm a beginner Angular developer so if anyone wants to bash my Angular skills go right ahead, but I primarily need help with figuring out how to access the file's content after uploading.</p>
<p>Let me know if I haven't been clear enough if y'all need more details.</p> | 2 |
Cannot cast App Delegate to App Delegate in XCTest | <p>I am working in an ios app in Xcode 7.3.1.In that I am trying to start unit testing on my swift iOS app. I cannot see to access anything that uses my appDelegate.I tried the following to solve from the following.But still am getting the same issue.Please help me to solve this.

<p>I am getting the following issue,while i am running unit test.
My sample code is</p>
<pre><code>import UIKit
import XCTest
@testable import MyAppName
class FreshBossTests: XCTestCase {
var login:LoginPageController!
override func setUp() {
super.setUp()
login = LoginPageController()

}
</code></pre>
<p>In my LoginPageController,I am having the following code.</p>
<pre><code>let appDelegate:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
</code></pre>
<p>In that line only am getting the error like </p>

Why does the Ruby module Kernel exist? | <p>In the book <em>OO Design in Ruby</em>, Sandi Metz says that the main use of modules is to implement duck types with them and include them in every class needed. Why is the Ruby <code>Kernel</code> a module included in <code>Object</code>? As far as I know it isn't used anywhere else. What's the point of using a module?</p> | 2 |
State of thread while in run() method (Java) | <p>I am trying to understand multithreading in java. As I was going through the various states a Java thread can be in (new, Runnable, Running, Waiting/Blocked, Dead). I tried to run some simple code to check the states of the thread.</p>
<p>I created a class <code>MyThread</code> that extends <code>Thread</code> and overrode <code>run()</code> method.</p>
<pre><code>package com.practice.threads;
public class MyThread extends Thread {
@Override
public void run() {
super.run();
System.out.println("Running Mythread.");
System.out.println("State of thread : " + this.getState()); // line 2
}
}
</code></pre>
<p>Now I have created a simple class to test the states of thread : </p>
<pre><code>package com.practice.threads;
public class ThreadStateDemo {
/**
* @param args
*/
public static void main(String[] args) {
MyThread myThread = new MyThread();
System.out.println("State of thread : " + myThread.getState()); // line 1
myThread.start();
}
}
</code></pre>
<p>Running this class give the following output : </p>
<pre>
State of thread : NEW
Running Mythread.
State of thread : RUNNABLE
</pre>
<p>The output of line 2 is something I don't understand. When <code>run()</code> method of a thread instance is being executed, how can it be in RUNNABLE state? I saw mention of a RUNNING state in a book (SCJP Suncertified Programmer). Should it not show RUNNING?</p> | 2 |
Using TLS 1.1/1.2 in WSO2 ESB out-going request | <p>I'm trying to consume a web service over HTTPS using WSO2 ESB (4.7.0). The web service requires all callers to use a TLS version >1.0 (1.1 or 1.2).</p>
<p>I'm using Java 1.7.</p>
<p>I've added the following line to my PassthroughTransportSender (and Receiver) definition to no avail:</p>
<pre><code><parameter name="HttpsProtocols">TLSv1.2</parameter>
</code></pre>
<p>How can I make WSO2 Callout and Send mediators use newer TLS versions (preferably TLS 1.2)?</p> | 2 |
Java iterator nextIndex pointer | <p>Could you explain behaviour of Iterator result:</p>
<pre><code> ArrayList< String > list = new ArrayList< >(
Arrays.asList( new String[] { "a", "b", "c", "d" } ) );
int i = 0;
ListIterator< String > iterator = list.listIterator();
while( iterator.hasNext() ) {
if( ++i == 3 ) {
System.out.println(
iterator.previous() + iterator.nextIndex() );
}
System.out.println( iterator.next() + iterator.nextIndex() );
}
</code></pre>
<p>The output is: a1 b2 b1 b2 c3 d4
Why third output is "b1" but not "a1"?
I figure the structure</p>
<p>0 1 2 3 element index</p>
<p>a b c d element value</p> | 2 |

Gmail API changes the content disposition from "inline" to "attachment" | <p>I'm running into an odd problem with sending inline attachments via Gmail's API. I am using the .NET client (version 1.10.0). The email is a reply to a message I've received with an inline attachment, so the attachment is part of the quoted block in the reply.</p>
<p>Here's the raw MIME message that I'm sending out:</p>

</code></pre>
<p>Note above the content disposition on the mime part for the inline attachment: </p>
<p><strong>Content-Disposition: <em>inline</em>; filename="ha ha.jpeg"</strong></p>
<p>Here's what the MIME headers on the inline attachment part look like when it comes in:</p>
<pre><code>Content-Type: image/jpeg; name="ha ha.jpeg"
Content-Disposition: attachment; filename="ha ha.jpeg"
Content-Transfer-Encoding: base64

X-Attachment-Id: 594301951148d672_0.1
</code></pre>
<p>My question is: why is the Content-Disposition now rewritten as <strong>attachment</strong> rather than <strong>inline</strong>?</p>
<p>I've found that when viewing the email in my browser, it appears as expected. But when viewing with my Mac's Mail client, the inline attachment appears in the email twice. I suspect that the change in the content disposition might be the reason- any light you can shed on this would be much appreciated!</p> | 2 |
TileOverlay with android and google maps | <p>I've used MapTiler to create some tiles that I'm trying to overlay onto a Google map with android and not having much luck. The Android documentation is pretty sparse on this topic but I've done what I think should work, yet I'm not seeing the tiles when I zoom in to the correct level. I'm trying to make the overlay happen in the onMapReady() callback, should I be doing that somewhere else?</p>
<p>Here's the code I have for the onMapReady method:</p>
<pre><code>@Override
public void onMapReady(GoogleMap googleMap) {
googleMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
googleMap.setMyLocationEnabled(true);
CameraPosition cameraPosition = new CameraPosition.Builder().target(new LatLng(44.481705,-114.9378269)).zoom(16).build();
googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
mTileOverlay = googleMap.addTileOverlay(new TileOverlayOptions()
.tileProvider((new UrlTileProvider(256, 256) {
@Override
public URL getTileUrl(int x, int y, int zoom) {
String s = "http://www.example.com/tiles/"+zoom+"/"+x+"/"+y+".png";
// added this logging to see what the url is
Log.d("home", s);
try {
return new URL(s);
} catch (MalformedURLException e) {
throw new AssertionError(e);
}
}
})));
}
</code></pre>
<p>any ideas here?</p>
<p>TIA</p>
<p>EDIT: I've adding some logging to see what 's' (my url) is returning, and it's returning the correct url and my server is serving up the tiles correctly from that url but still not seeing anything on the map in android.</p> | 2 |

<blockquote>
<p>It used an internal, per-thread context to track state across calls,
as is done for strtok. The function now has the signature
<code>wchar_t* wcstok(wchar_t*, wchar_t const*, wchar_t**)</code>, and requires the caller
to pass the context as a third argument to the function.</p>

<p>At the cost of sounding inherently stupid, I will still go ahead and ask,
Can anybody please explain the purpose of this third parameter in simple terms and how it has changed <code>std::wcstok</code> from its earlier version?</p> | 2 |
.NET DPAPI and AES Encryption: Sense-Check | <p>I am just about to write a new encryption system for a website I'm currently working on, and wanted to see if i could get someone to sense-check it before I get started if possible!</p>
<p><strong>Update:</strong> <strong><em>Should have been clearer with my original question. I need to encrypt some user data that I also need to be able to read back at a later data. And, I also need to store the users password or a hash of the password for verifying the user upon login.</em></strong></p>
<p>The plan is:</p>
<ol>
<li><p><strong>Master Key:</strong> Create a DPAPI key-setter application to take a text-based master key, encrypt via DPAPI, then save the encrypted output to a text file on the server. This is a one-off task that I'll perform every time I move the site to a new server. The master key will be used to perform AES encryption.</p></li>
<li><p><strong>When a new user registers:</strong></p>
<p>2.1. Save password data / hash of password data.</p>
<p>2.2. Load master key file, decrypt the key using DPAPI. Use the decrypted master key, and a new random IV for each piece of user data to create an AES-encrypted string. Save each encrypted string by prefixing the encrypted string with the corresponding random IV, and insert into a varchar column in the database.</p></li>
<li><p><strong>Upon user login:</strong></p>
<p>3.1. Match password hash to validate user. </p>
<p>3.2. For each encrypted user data field, split content into two parts: the IV and the encrypted data. Taking the master key from DPAPI, and the IV, decrypt the data and display on-screen.</p></li>
</ol>
<p>How does that sound? Are there any obvious flaws to the above? </p>
<p>I'm new to this having previously used Enterprise Library Security for this sort of the stuff in the past (which is no longer available in .NET core!), so any help would be massively appreciated!</p> | 2 |

Check login status in routeProvider | <p>I'm working on an Angular project but I'm having a little problem and I'd appreciate any help because I'm really lost. Basically I need to check if a user is logged in, and if he is, he should not be allowed to access a certain view/route, here's the code I'm using for this:</p>
<pre><code>'use strict';
angular.module('testApp')
.config(function ($routeProvider) {
$routeProvider
.when('/registroVisitante', {
template: '<registro-visitante></registro-visitante>',
resolve: {
"check": function(Auth, $location) {
console.log(Auth.isLoggedIn());
if (!Auth.isLoggedIn()) {
alert("Access allowed");
} else {
$location.path('/'); //redirect user to home.
alert("Access denied");
}
}
}
});
});
</code></pre>
<p>The problem itself is that, this is actually working, but only when I try to access the route via an anchor click or ng-click or whatever, however, when I type the route in the address bar it lets me access but it shouldn't, anyone has any idea why?</p> | 2 |
Value of a short variable in C | <p>I have a simple program with a short variable declaration:</p>
<pre><code> short int v=0XFFFD;
printf("v = %d\n",v);
printf("v = %o\n",v);
printf("v = %X\n",v);
</code></pre>
<p>The result is:</p>
<pre><code>v = -3 ; v = 37777777775 ; v = FFFFFFFD
</code></pre>
<p>I don't understand how to calculate these values. I know that a short variable can hold values between -32768 and 32767, and the value 0XFFFD causes an overflow, but I don't know how to calculate the exact value, which is -3 in this case.</p>
<p>Also, if my declaration is v=0XFFFD why the output v=%X is FFFFFFFD?</p> | 2 |
