AWS - Can't detaching network interfaces - You are not allowed to manage 'ela-attach' attachments : <p>I did the AWS mysfits tutorial and I thought the cleanup would be as simple as deleting the Cloud Formation stack. However, items failed to delete so I am trying to clean them up manually to assist the Cloud Formation stack deletion.</p>
<p>I keep getting an error when trying to Detach the network interfaces (I am logged into the root account):</p>
<p>Error detaching network interfaces:</p>

Python Data-Scraping Differentiation - millions vs. ones : <p>I'm currently scraping some tables on the internet where numbers are posted in varying numerical formats:</p>
<pre><code>Animal - Left in Wild
Tigers - 18
Deer - 18m
Pigs - 180000
</code></pre>
<p>I've managed to strip the m away from the number, but I am wondering if/how I could use a if statement to allow some manipulation to ensure I document the number accurately:</p>
<pre><code>if animal.strip("m") == animal.strip("m"):
left_in_wild = left_in_wild * 1000000
</code></pre>
<p><em>Obviously that code does not work, but it is a rough thought</em> of how I'm thinking about getting around this. If anyone can has anything they think can be helpful let me know.</p>
<p>Thank you!</p>

How to define a float array in C : I am working a debian 7, using gcc.
I initialize a test vector as follows:
float test_vec[] = {4.31,3.33,1.58,0.75,7.82,1.85,0.45,0.11,0.98,3.45};
The sizeof() function applied to this vector returns 40.
I use a for() to printf each element and most of them are zero or very large positive/negative numbers.
How I should define the test_vector in order to get the right size? | 0debug |

Logging stdout with python3 and uWSGI : <p>I have a python 2 flask app running behind uWSGI, which is managed by supervisord. Logs are being written to sys.stdout by the flask app. These logs are then picked up by uWSGI and written to file by supervisord. uWSGI logs are written to /dev/stderr. See the supervisord conf below.</p>
<pre><code>[program:uwsgi]
command = uwsgi --ini /etc/uwsgi.conf --master
directory = /app
autostart = true
autorestart = true
stdout_logfile = /var/log/myapplication/application.log
stdout_logfile_maxbytes = 50000000
stdout_logfile_backups = 3
stderr_logfile = /dev/stderr
stderr_logfile_maxbytes = 0
stopsignal = INT
</code></pre>
<p>This works great! I have nicely separated application logs and uWSGI logs.</p>
<p>I've now upgraded to python 3. This has all gone fine, except the application logs are now ending up in uWSGI's stderr, mixed in with the uWSGI logs.</p>
<p>I've trawled the uWSGI docks, and have not been able to find a reason for this change between python 2 and python 3.</p>
<p>I've tried redirecting when defining the socket, like is suggested here <a href="http://lists.unbit.it/pipermail/uwsgi/2016-February/008383.html" rel="noreferrer">http://lists.unbit.it/pipermail/uwsgi/2016-February/008383.html</a> but that just redirects everything (application and uWSGI logs) to <code>/dev/null</code>.</p>
<p>I also found this <a href="http://lists.unbit.it/pipermail/uwsgi/2016-January/008353.html" rel="noreferrer">http://lists.unbit.it/pipermail/uwsgi/2016-January/008353.html</a> but could't find anything about pyimport-shared.</p>
<p>Does anyone know what might be going on?</p>
<p>My uWSGI conf is here if it help.</p>
<pre><code>[uwsgi]
uid = www-data
gid = www-data
module = application:application
socket = /run/uwsgi.sock
single-interpreter = true
enable-threads = true
buffer-size = 16384

Run a link 100 times using Perl : The problem I met is that I need to run one link (I cannot be specific that link exactly, this link is doing request and looks like http://link.com/?name=name&password=password& and etc)
And I need to run this link 100 times in a row. I can not do this manually using browser - this tooks much time.
Is there any option to run (just run, like you put link in browser and press enter) this link 100 times in a row using Perl scripting?
I have not met before with the Perl and therefore asking the help directly. As I google before some information and make a little script, but seems like I missing something in my knowledge:
#!/usr/bin/perl -w
use LWP::Simple;
my $uri = 'http://my link here';
my $content = get $uri;
Could you please advice to me how I can finish this script? | 0debug |

Also if you guys have any good resources on <code>Deep Learning in Computer Vision</code> that would be great too. Thank you in advance!</p>

The code，following the line " new ClassReader(classfileBuffer)" is unreachable : I want to add monitor code into some class,so i use the java agent and asm4 to manipulate the byte code.
The core code as followed:
public class MyClassFileTransformer implements ClassFileTransformer {
@Override
public byte[] transform(ClassLoader loader, String className,
Class<?> classBeingRedefined, ProtectionDomain protectionDomain,
byte[] classfileBuffer) throws IllegalClassFormatException {
if (className.startsWith("com/dgl/asm/SleepClass")) {
ClassReader reader = new ClassReader(classfileBuffer);
System.out.println("1231231231312");
ClassWriter cw = new ClassWriter(reader,0);
ClassVisitor adpter = new AddTimerClassAdpter(Opcodes.ASM4, cw);
reader.accept(adpter, 0);
return cw.toByteArray();
}
return classfileBuffer;
}
}
However,the code ,after "ClassReader reader = new ClassReader(classfileBuffer)",is always unreachable.After the "new ClassReader(classfileBuffer)" be executed,the program jumps to the main method directly without any exception!
what should I do? Any idea?

Show user-friendly error page instead of exception in Flutter : <p>Is it possible to make <strong>global error handling</strong> that will <strong>show user-friendly error page instead of showing red exception</strong>?</p>
<p>I already made error handling (<a href="https://flutter.io/docs/cookbook/maintenance/error-reporting" rel="noreferrer">here</a>) that will report exception to the backend but what I really would like to achieve is to hide red exception and show something a little bit frendlier.</p>
<p>I searched everywhere and I found literally nothing. I'm sorry that I don't have any code to show because I have no idea how to start.</p>

Value that occurs consecutively most no of times in array : The following code is in java lang:<br>
int[] array = {1,2,2,3,3,3,2,2,1};
int k = 2;
What i need to do is find the value (in this case 3), that occurs consecutively more than k times. There can be only one value that occurs>k and if no such value exists, print -1.
Explanation: <br>1 occurs only 1 time consecutively. <br>2 occurs 2 times but its not>k.<br> 3 occurs 3 times, which is>k. Since, there can be only one possible answer, you can stop searching for answer in further values and print 3.<br>

Equivalent to get_contents_to_file in boto3 : <p>In boto3, is there an equivalent of <a href="http://boto.cloudhackers.com/en/latest/ref/s3.html#boto.s3.key.Key.get_contents_to_file" rel="noreferrer"><code>get_contents_to_file</code></a>, that copies the contents of an object to a file handle?</p>
<p>In boto, if I have an S3 object <code>key</code>, I can copy the contents to a temporary file with:</p>
<pre><code>from tempfile import TemporaryFile
key = code_that_gets_key()
with TemporaryFile() as tmp_file:
key.get_contents_to_file(key, tmpfile)
</code></pre>
<p>I haven't found an equivalent in boto3. </p>
<p>I have been able to replace usage of <a href="http://boto.cloudhackers.com/en/latest/ref/s3.html#boto.s3.key.Key.get_contents_to_filename" rel="noreferrer"><code>get_contents_to_filename</code></a> with <a href="http://boto3.readthedocs.org/en/latest/reference/services/s3.html?highlight=download_file#S3.Object.download_file" rel="noreferrer"><code>download_file</code></a>. However, that covers the case where I provide the filename. In this case, I want to provide the file handle as the argument.</p>
<p>Currently, I can get the code to work in boto3 by iterating over the body as follows:</p>
<pre><code>with TemporaryFile() as tmp_file:
body = key.get()['Body']
for chunk in iter(lambda: body.read(4096), b''):
filehandle.write(chunk)
</code></pre>
<p>Is there a better way to do this in boto3?</p>

if change == "No":
print("You logged in as" , userp1)
else:
userp1 = input("What would your new username be?")
print("You logged in as",userp1)

Display specific data from sql database : I have a database called 'members' with a table called 'users'. The users table has an 'id' column that auto-increments every time a new user is added. I want to fetch the id of the logged in user and display that singular row of data.
This is my login code:
<?php
session_start();
// Connect to server and select databse.
mysql_connect("localhost", "root", "")or die("cannot connect");
mysql_select_db("members")or die("cannot select DB");
// username and password sent from form
$prepreemail=$_POST['email'];
$prepremypassword=$_POST['mypassword'];
$preemail = stripslashes($prepreemail);
$premypassword = stripslashes($prepremypassword);
$email = mysql_real_escape_string($preemail);
$mypassword = mysql_real_escape_string($premypassword);
$sql="SELECT * FROM users WHERE email='$email' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
header ("location:home.html");
}
else
{
header ("location:sign_in.php");
}
?>
This is my sign up code
<?php
session_start();
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("members", $con);
$sql="INSERT INTO users (name, email, address, dob, password)
VALUES
('$_POST[name]','$_POST[email]','$_POST[address]','$_POST[dob]','$_POST[mypassword]')";
if (!mysql_query($sql,$con)) die('Error: ' . mysql_error());
$_SESSION['userID'] = "SELECT id from users";
{
header ("Location: sign_in.php");
exit;
}
mysql_close($con)
?>
And this is my display user details code:
<?php
session_start();
// Create connection
$conn = new mysqli("localhost", "root", "", "members");
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$userID = $_SESSION['userID'];
$sql = "SELECT name, email, address, dob FROM users WHERE `users`.`id`=$userID";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo "<table><tr><th>Name</th><th>Email</th><th>Address</th><th>DOB</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {

Holding onto a MTLTexture from a CVImageBuffer causes stuttering : <p>I'm creating a <code>MTLTexture</code> from <code>CVImageBuffer</code>s (from camera and players) using <code>CVMetalTextureCacheCreateTextureFromImage</code> to get a <code>CVMetalTexture</code> and then <code>CVMetalTextureGetTexture</code> to get the <code>MTLTexture</code>.</p>
<p>The problem I'm seeing is that when I later render the texture using Metal, I occasionally see video frames rendered out of order (visually it stutters back and forth in time), presumably because CoreVideo is modifying the underlying <code>CVImageBuffer</code> storage and the <code>MTLTexture</code> is just pointing there.</p>
<p>Is there any way to make CoreVideo not touch that buffer and use another one from its pool until I release the <code>MTLTexture</code> object?</p>
<p>My current workaround is blitting the texture using a <code>MTLBlitCommandEncoder</code> but since I just need to hold on to the texture for ~30 milliseconds that seems unnecessary.</p>

<li>I need to be able to then place another image on it and position it (hopefully with CSS-esque type rules like width:150px; height:80px; left: 30px; top:30px; transform: rotate(7deg);" etc etc.</li>

How to assert that a constexpr if else clause never happen? : <p>I want to raise a compile time error when non of the constexpr if conditions is true eg:</p>

} else {
// I want the else clause never taken. But I heard the code below is not allowed
static_assert(false);

<p>For example, what does <code>"foo" =~ "foo"</code> mean?
How is it different from <code>"foo" == "foo"</code>?</p>

Django: GenericForeignKey and unique_together : <p>In the application I'm working on I'm trying to share access tokens within a company. Example: a local office can use the headquarter's tokens to post something on their Facebook page.</p>
<pre><code>class AccessToken(models.Model):
"""Abstract class for Access tokens."""
owner = models.ForeignKey('publish.Publisher')
socialMediaChannel = models.IntegerField(
choices=socialMediaChannelList, null=False, blank=False
)
lastUpdate = models.DateField(auto_now=True)
class Meta:
abstract = True
</code></pre>
<p>Since Facebook, Twitter and other social media sites handle access tokens in their own way I made and abstract class AccessToken. Each site gets its own class e.g. </p>
<pre><code>class FacebookAccessToken(AccessToken):
# class stuff
</code></pre>
<p>After doing some reading I found out that I must use a <code>GenericForeignKey</code> to point to classes that inherit <code>AccessToken</code>. I made the following class:</p>
<pre><code>class ShareAccessToken(models.Model):
"""Share access tokens with other publishers."""
sharedWith = models.ForeignKey('publish.Publisher')
sharedBy = models.ForeignKey(User)
# for foreignkey to abstract model's children
contentType = models.ForeignKey(ContentType)
objectId = models.PositiveIntegerField()
contentObject = GenericForeignKey('contentType', 'objectId')
class Meta:
unique_together = (('contentObject', 'sharedWith'))
</code></pre>
<p>When I run the django test server I get the following error:</p>
<blockquote>
<p>core.ShareAccessToken: (models.E016) 'unique_together' refers to field
'contentObject' which is not local to model 'ShareAccessToken'. HINT:
This issue may be caused by multi-table inheritance.</p>
</blockquote>
<p>I don't understand why I get this error, first time using <code>GenericForeignKey</code>. What am I doing wrong?</p>
<p>If there is a smarter way to share the access tokens I would love to hear about it.</p>

Multiple Case Expressions ruby : I have two fields field1 and field2. I need to do a case on both the fields and switch it into corresponding when outputs
case field1
when "val1"
puts field1
when "val2"
puts field2
end
case field2
when "val1"
puts field1
when "val2"
puts field2
end
So, how can i implement something like above in a single case statement
something like this
case field1,field2
when "val1"
puts field1
when "val2"
puts field2
end
will any monkey patching help??

WINDOWS API: GetCurrentThread(); in C : <p>I just started my college "adventures", and one of them is subject called operating systems. I must admit that the subject is the most boring ever. Last week, we got our first homework, and i do not know what to do as this is the first time ever i come up with Windows API functions or this topic in general. The task is very simple, we need to write very basic code in C that shows how does GetCurrentThread() work!!!???? I tried looking for solution online, but I could not find anything and our professor is not doing anything to help us. I found the use of functions like GetCurrentThreadID() but that is not what i need. Can somebody write simple program ( 20-30 lines of code ) which contains the use of this function (in C)?</p>

With registered - it's ok, understandable.
But what i can do, if user is not authorized, has disabled cookies and javascript?
How should i make unique 'quest' user?
I thought about IP addr, but it can be dynamic or You can visit web site through proxy, so that is not a solution?</p>

New debug icon "Step F9" in Chrome Dev Tools : <p>So what does this actualy do?</p>
<p><a href="https://i.stack.imgur.com/lh01n.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/lh01n.jpg" alt="enter image description here"></a></p>
<p>I searched trough the release notes of the Chrome Dev Tools and couldn't find a trace of it. None of the tutorials out there don't mention it either so I'm guessing it's new.</p>
<p>Experimenting with some code I seems to behave the same as "Step Into" and couldn't find a difference.</p>

How to train TensorFlow network using a generator to produce inputs? : <p>The TensorFlow <a href="https://www.tensorflow.org/versions/r0.10/how_tos/reading_data/index.html" rel="noreferrer">docs</a> describe a bunch of ways to read data using TFRecordReader, TextLineReader, QueueRunner etc and queues.</p>
<p>What I would like to do is much, much simpler: I have a python generator function that produces an infinite sequence of training data as (X, y) tuples (both are numpy arrays, and the first dimension is the batch size). I just want to train a network using that data as inputs. </p>
<p>Is there a simple self-contained example of training a TensorFlow network using a generator which produces the data? (along the lines of the MNIST or CIFAR examples)</p>

why my python cannot read files on my desktop : I'm new here and in python. There are 2 questions I'd like to ask:
1) I'm reading a .dat file on my desktop into my spider, but it shows No such file or directory: 'C:\\Desktop\\movies.dat', but if I put the file into the default folder, 'C:\\Users\\User\\.spyder-py3\\movies.dat', it can read the file successfully. I thought that python3 can file the path in the quotes no matter if it is a default folder or not.
2) I've been reading some python books and in every beginning of each book, there is a chaper introducing Ipython and Jupyter orsomething like that, I don't quite understand what's the difference between, like, Anaconda, Spider, Jupyter notebook and Ipython. I'm currently using Spider and wondering what's the difference.
Great thanks if anythong can help! | 0debug |
Could someone please help me here? : I am new to android and doing some basic activities on android studio. I have the following code which will redirect from LoginActivity to Navigation activity after successful login.
**LoginActivity.java code below:-**
if (cancel) {
// There was an error; don't attempt login and focus the first
// form field with an error.
focusView.requestFocus();
} else {
// Show a progress spinner, and kick off a background task to
// perform the user login attempt.
showProgress(true);
mAuthTask = new UserLoginTask(email, password);
mAuthTask.execute((Void) null);
if(loginPassed) {
Intent intent = new Intent(this, com.example.jjefry.myapplication.NavigationActivity.class);
intent.putExtra(EXTRA_MESSAGE, "Jefry");
startActivity(intent);
}
}
***loginPassed*** variable is set to true if the credentials are correct else it will be false.
If I remove ***if*** condition in the above program if will redirect to NavigationActivity properly but with ***if*** condition in place, it will simple close the application.
Not sure where am I going wrong, please help me with this. | 0debug |
