How to elegantly check if a number is within a range? | <p>How can I do this elegantly with C#?</p>
<p>For example, a number can be between 1 and 100.</p>
<p>I know a simple <code>if (x >= 1 && x <= 100)</code> would suffice; but with a lot of syntax sugar and new features constantly added to C#/.Net this question is about more idiomatic (one can all it elegance) ways to write that.</p>
<p>Performance is not a concern, but please add performance note to solutions that are not O(1) as people may copy-paste the suggestions.</p> | 0 |

"You don't have an extension for debugging 'JSON with Comments'" warning when debugging VS Code theme | <p>I generated the files necessary for creating a color theme in VS Code. I did this with the <a href="https://www.npmjs.com/package/generator-code" rel="noreferrer">generator-code</a> node package.<br></p>
<p><a href="https://i.stack.imgur.com/aHL8k.png" rel="noreferrer">My file structure is as follows</a><br></p>

<p>In reality I have a dataset of 50,000 columns of 479 rows. My objective is to go through each column with characters and convert the data to integers depending on which is the most abundant character.</p>
<p>Right now I have the data input, and I have more or less written the function I would like to use to analyze each column separately. However, I can't quite understand how to use a forloop or use the apply function through all of the columns in the dataset. I would prefer not to hardcode the columns because I will have 40,000~50,000 columns to analyze. </p>
<p>My code so far is:</p>
<pre><code>import pandas as pd
df = pd.read_csv("/home/dfreese/Desktop/testSNPtext", delimiter='\t')
df.head() # check that the file format fits
# ncol df
df2 = df.iloc[4:-1] # Select the rows you want to analyze in a subset df
print(df2)
</code></pre>
<p>My function: </p>
<pre><code>def countAlleles(N):
# N is just suppose to be the column, ideally once I've optimized the function
# I need to analyze every column
# Will hold the counts of each letter in the column
letterCount = []
# This is a parallel array to know the order
letterOrder = {'T','A','G','C','H','U'}
# Boolean to use which one is the maximum
TFlag = None
AFlag = None
GFlag = None
CFlag = None
HFlag = None
UFlag = None
# Loop through the column to determine which one is the maximum
for i in range(len(N)): # How do I get index information of the column?
if(N[i] == 'T'): # If the element in the column is T
letterCount[0] = letterCount[0] + 1
elif(N[i] == 'A'):
letterCount[1] = letterCount [1] + 1
elif (N[i] == 'G'):
letterCount[2] = letterCount [2] + 1
elif (N[i] == 'C'):
lettercount[3] = letterCount[3] + 1
elif(N[i] == 'H'):
letterCount[4] = letterCount[4] + 1
else:
letterCount[5] = letterCount[5] + 1
max = letterCount[0] # This will hold the value of maximum
mIndex = 0 # This holds the index position with the max value
# Determine which one is max
for i in range(len(letterCount)):
if (letterCount[i] > max):
max = letterCount[i]
mIndex = i
</code></pre>
<p>So I designed the function to input the column, in hopes to be able to iterate through all the columns of the dataframe. My main question is: </p>
<p>1) How would I pass each in each column as a parameter to the for loop through the elements of each column?</p>
<p>My major source of confusion is how indexes are being used in pandas. I'm familiar with 2-dimensional array in C++ and Java and that is most of where my knowledge stems from.</p>
<p>I'm attempting to use the apply function: </p>
<pre><code>df2 = df2.apply(countAlleles('ss715583617'), axis=2)
</code></pre>
<p>but it doesn't seem that my application is correct.</p> | 0 |
How to solve error: "Invalid type in JSON write (NSConcreteData)" | <p>I'm trying to write some code to validate a subscription on my iOS App. I'm following this tutorial: <a href="http://savvyapps.com/blog/how-setup-test-auto-renewable-subscription-ios-app/" rel="nofollow">http://savvyapps.com/blog/how-setup-test-auto-renewable-subscription-ios-app/</a></p>

Include my markdown README into Sphinx | <p>I would like to include my project's <code>README.md</code> into my Sphinx documentation like in
<a href="https://stackoverflow.com/questions/10199233/can-sphinx-link-to-documents-that-are-not-located-in-directories-below-the-root">Can sphinx link to documents that are not located in directories below the root document?</a>
- which is that in the resulting Sphinx html documentation I click on a link in the table of contents on the welcome page and get to the <code>README.md</code>.</p>
<p>For that a document <code>readme_link.rst</code> is created which contains the lines</p>
<pre><code>Readme File

.. include:: ../../README.md
</code></pre>
<p>and I add the line</p>
<pre><code>README <readme_link>
</code></pre>
<p>into the toctree of <code>index.rst</code>.
Going with that, my <code>README.md</code> is not parsed as Markdown, but just printed onto the page as-is-text.</p>
<p>I thought an alternative idea might be to have a markdown file <code>readme_link.md</code> instead, but there is no way to include files with markdown.</p>
<p><strong>How can I have my README.md parsed as markdown?</strong></p>
<p>(Of course I don't want to rewrite it as .rst.)</p>
<h2>Why <a href="https://github.com/miyakogi/m2r#sphinx-integration" rel="noreferrer">m2r</a> is not working</h2>

<p>and I get the error <code>WARNING: ../README.md:48: (SEVERE/4) Title level inconsistent:</code>. I understand from <a href="https://stackoverflow.com/questions/24504301/what-does-title-level-inconsistent-mean">What does "Title level inconsistent" mean?</a> that I need to use other symbols - but reading into them I realized that the answer refers to <code>rst</code> symbols.

How to prevent the ip address of hyper-v virtual switch from being changed? | <p>I have a laptop with Windows 10 2004 installed. I configureded Hyper-V and created two VMs: On one VM runs windows 10 to enclose serveral malware IM softwares which I have to use for working contacts. On the other VM runs ubuntu server 20.04 for development.</p>
<p>I configured Hyper-V with a virtual switch of type internal network and Hyper-V automatically specified the virtual switch with a static IP. I want to connect to ubuntu with machine name. So I specified ubuntu VM with a static IP and added an item in the hosts file of the host windows 10. Then I can use the remote over SSH feature of VS Code to develop node.js app in windows 10 host. Everything went ok till I had restarted my laptop.</p>
<p>After I have restarted the laptop, the IP address of the hyper-v virtual switch was changed. I couldn't reconnect to VM ubuntu any more because the VM ubuntu was configured with a static IP and default gateway based on the old IP of the virtual switch.</p>
<p>I checked the IPv4 properties of the virtual switch via UI, It's configured as "using the following IP", so I thought of the IP shouldn't change. But I was wrong. Each time after my laptop being restarted, the "static IP" of virtual switch always changes. This change breaks the connection to VM ubuntu.</p>
<p>So, is there any way to prevent the IP address of the virtual switch from being changed? Or some way to add name resolving mechanism to Hyper-V virtual switch (then I can configure using dynamic IP address in VMs)?</p> | 0 |

How to properly create gcp service-account with roles in terraform | <p>Here is the terraform code I have used to create a service account and bind a role to it: </p>
<pre><code>resource "google_service_account" "sa-name" {
account_id = "sa-name"
display_name = "SA"
}
resource "google_project_iam_binding" "firestore_owner_binding" {
role = "roles/datastore.owner"
members = [
"serviceAccount:sa-name@${var.project}.iam.gserviceaccount.com",
]
depends_on = [google_service_account.sa-name]
}
</code></pre>
<p>Above code worked great... except it removed the <code>datastore.owner</code> from any other service account in the project that this role was previously assigned to. We have a single project that many teams use and there are service accounts managed by different teams. My terraform code would only have our team's service accounts and we could end up breaking other teams service accounts.</p>
<p>Is there another way to do this in terraform?</p>
<p>This of course can be done via GCP UI or gcloud cli without any issue or affecting other SAs.</p> | 0 |

Emulating a mobile screen size through an iframe | <p>Just a random thought,
What if I wanted to showcase a responsive webdesign not by resizing the browser window, but actually loading the responsive site in an IFRAME having the same dimension as that of a mobile screen. Can this work?</p>
<p>assuming that I have an IFRAME </p>
<pre><code><iframe src="something" id="viewPort"/>
</code></pre>
<p>into which I load the responsive website. and then let the user test by adjusting the iframe width and height in their browser.</p>
<p>IF this can work it can be a boon for clients who don't know a thing about browsers.</p> | 0 |
Setting Access-Control-Allow-Origin header on source server | <p>I am using <code>$.get</code> to parse an RSS feed in jQuery with code similar to this:</p>
<pre><code>$.get(rssurl, function(data) {
var $xml = $(data);
$xml.find("item").each(function() {
var $this = $(this),
item = {
title: $this.find("title").text(),
link: $this.find("link").text(),
description: $this.find("description").text(),
pubDate: $this.find("pubDate").text(),
author: $this.find("author").text()
}
//Do something with item here...
});
});
</code></pre>
<p>However, due to the Single Origin Policy, I'm getting the following error:</p>
<blockquote>
<p>No 'Access-Control-Allow-Origin' header is present on the requested resource.</p>
</blockquote>
<p>Fortunately I have access to the source server, as this is my own dynamically created RSS feed.</p>
<p>My question is: how do I set the Access-Control-Allow-Origin header on my source server?</p>
<p><strong>Edit</strong></p>
<p>I'm using PHP and I think my webserver is Apache.</p> | 0 |

How to remove selected items from a listbox | <p>This is for a VB.NET 4.5 project in VS2015 Community.</p>
<p>I am trying to remove certain selected items from a listbox, but only if the selected item meets a condition. I've found plenty of examples on how to remove selected items. But nothing that works with a condition nested in the loop going through the selected items (at least, I can't get the examples to work with what I'm trying to do...)</p>
<p>Here's my code:</p>
<pre><code> Dim somecondition As Boolean = True
Dim folder As String
For i As Integer = 0 To lstBoxFoldersBackingUp.SelectedItems.Count - 1
If somecondition = True Then
folder = lstBoxFoldersBackingUp.SelectedItems.Item(i)
Console.WriteLine("folder: " & folder)
lstBoxFoldersBackingUp.SelectedItems.Remove(lstBoxFoldersBackingUp.SelectedItems.Item(i))
End If
Next
</code></pre>
<p>The console output correctly shows the text for the current iteration's item, but I can't get the Remove() to work. As the code is now, I get the console output, but the listbox doesn't change.</p> | 0 |

Can an "SEO Friendly" url contain a unique ID? | <p>I'd like to start using "SEO Friendly Urls" but the notion of generating and looking up large, unique text "ids" seems to be a significant performance challenge relative to simply looking up by an integer. Now, I know this isn't as "human friendly", but if I switched from</p>
<pre><code>http://mysite.com/products/details?id=1000
</code></pre>
<p>to</p>
<pre><code>http://mysite.com/products/spacelysprokets/sproket/id
</code></pre>
<p>I could still use the ID alone to quickly lookup the details, but the URL itself contains keywords that will display in that detail. Is that friendly enough for Google? I hope so as it seems a much easier process than generating something at the end that is both unique and meaningful.</p>
<p>Thanks!</p>

What exactly is nullptr? | <p>We now have C++11 with many new features. An interesting and confusing one (at least for me) is the new <code>nullptr</code>.</p>
<p>Well, no need anymore for the nasty macro <code>NULL</code>.</p>
<pre><code>int* x = nullptr;
myclass* obj = nullptr;
</code></pre>
<p>Still, I am not getting how <code>nullptr</code> works. For example, <a href="http://en.wikipedia.org/wiki/C%2B%2B11#Null_pointer_constant" rel="noreferrer">Wikipedia article</a> says:</p>
<blockquote>
<p>C++11 corrects this by introducing a new <strong>keyword</strong> to serve as a distinguished null pointer constant: nullptr. It is of <strong>type nullptr_t</strong>, which is implicitly convertible and comparable to any pointer type or pointer-to-member type. It is not implicitly convertible or comparable to integral types, except for bool.</p>
</blockquote>
<p>How is it a keyword and an instance of a type?</p>
<p>Also, do you have another example (beside the Wikipedia one) where <code>nullptr</code> is superior to good old <code>0</code>?</p> | 0 |
How can I color Python logging output? | <p>Some time ago, I saw a Mono application with colored output, presumably because of its log system (because all the messages were standardized). </p>
<p>Now, Python has the <code>logging</code> module, which lets you specify a lot of options to customize output. So, I'm imagining something similar would be possible with Python, but I can’t find out how to do this anywhere. </p>
<p>Is there any way to make the Python <code>logging</code> module output in color? </p>
<p>What I want (for instance) errors in red, debug messages in blue or yellow, and so on. </p>
<p>Of course this would probably require a compatible terminal (most modern terminals are); but I could fallback to the original <code>logging</code> output if color isn't supported.</p>
<p>Any ideas how I can get colored output with the logging module?</p> | 0 |

How to start/stop/restart a thread in Java? | <p>I am having a real hard time finding a way to start, stop, and restart a thread in Java.</p>
<p>Specifically, I have a class <code>Task</code> (currently implements <code>Runnable</code>) in a file <code>Task.java</code>. My main application needs to be able to START this task on a thread, STOP (kill) the thread when it needs to, and sometimes KILL & RESTART the thread...</p>
<p>My first attempt was with <code>ExecutorService</code> but I can't seem to find a way for it restart a task. When I use <code>.shutdownnow()</code> any future call to <code>.execute()</code> fails because the <code>ExecutorService</code> is "shutdown"...</p>

Can an oracle SQL query execute a string query selected from a table? | <p>When using oracle SQL is it possible to run a query based on a text_string from a subquery?
An example might clarify what I'm trying to do</p>
<pre><code> select count(sql_text), sql_text
from
(select sql_text
from query_table) sql_table
group by sql_text;
</code></pre>
<p>The outer query is intended to count the number of results for each query retrieved from the query_table.</p>
<p>Is there some way I can execute the sql statements I retrieved from my query_table in the same query?</p>
<p>Thanks</p>
<p>EDIT:
I was able to query sql from a table using the dbms_xmlgen.get_xml() function. I suppose that any command which caused the sql to be parsed and executed would work.
That being said, here's the generic code that I was able to accomplish things with:</p>
<pre><code> select to_number (
extractvalue(
xmltype(
dbms_xmlgen.getxml('select count(*) c from '|| table_name)), '/ROWSET/ROW/C'))counter,
sql_text
from
(select '('||sql_text||')' table_name
from query_table) sql_table;
</code></pre>
<p>While perhaps not the most elegant way to do things, it works and is a single sql statement.</p> | 0 |

<pre><code>CypressError: Timed out retrying: cy.click() failed because this element is detached from the DOM.

Cypress requires elements be attached in the DOM to interact with them.
The previous command that ran was:
> cy.debug()
This DOM element likely became detached somewhere between the previous and current command.
Common situations why this happens:
- Your JS framework re-rendered asynchronously
- Your app code reacted to an event firing and removed the element
You typically need to re-query for the element or add 'guards' which delay Cypress from running new commands.

What is a container manifest? | <p>The only <a href="https://docs.docker.com/registry/spec/manifest-v2-2/" rel="noreferrer">doc</a> on this topic seems to assume I already know what a manifest is, the problem it solves, and how it fits into the docker ecosystem. After reading the doc I'm still not sure how manifests actually work.</p>
<p>My private GCR contains manifest files- don't really understand their purpose. Does docker hub also use manifest files? I can see they contain the layers and hashes of each layer, but I'm still unclear on how docker generates/uses them.</p>

Magento: Disable module for any particular store | <p>Suppose, I have 3 stores.</p>
<p>I want to disable a module in Store 2. I only want it to be enabled in Store 1 and Store 3.</p>
<p>I see that I can do it by:- </p>
<ul>
<li><p>Going to <strong>System -> Configuration -> Advanced</strong> </p></li>
<li><p>Selecting desired store from <strong>Current Configuration Scope</strong> dropdown list.</p></li>
</ul>
<p>But this does not work fully.</p>
<p>And, I also don't want to check store in the module code itself or create system configuration field for the module to check/uncheck store to enable/disable.</p>
<p>What I am expecting is by adding some code in <strong>app/etc/modules/MyNamespace_MyModule.xml</strong>. Can we do it this way?</p> | 0 |

Python realtime plotting | <p>I acquire some data in two arrays: one for the time, and one for the value. When I reach 1000 points, I trigger a signal and plot these points (x=time, y=value).</p>
<p>I need to keep on the same figure the previous plots, but only a reasonable number to avoid slowing down the process. For example, I would like to keep 10,000 points on my graph.
The matplotlib interactive plot works fine, but I don't know how to erase the first points and it slows my computer very quickly.
I looked into matplotlib.animation, but it only seems to repeat the same plot, and not really actualise it.</p>
<p>I'm really looking for a light solution, to avoid any slowing.</p>
<p>As I acquire for a very large amount of time, I erase the input data on every loop (the 1001st point is stored in the 1st row and so on).</p>
<p>Here is what I have for now, but it keeps all the points on the graph:</p>
<pre><code>import matplotlib.pyplot as plt
def init_plot():
plt.ion()
plt.figure()
plt.title("Test d\'acqusition", fontsize=20)
plt.xlabel("Temps(s)", fontsize=20)
plt.ylabel("Tension (V)", fontsize=20)
plt.grid(True)
def continuous_plot(x, fx, x2, fx2):
plt.plot(x, fx, 'bo', markersize=1)
plt.plot(x2, fx2, 'ro', markersize=1)
plt.draw()
</code></pre>
<p>I call the init function once, and the continous_plot is in a process, called every time I have 1000 points in my array.</p> | 0 |
What is the difference between a Local Database in C# and a SQL Server Management Studio created database? | <p>I'm creating an application with MS Visual C# 2010 Express that requires a database.</p>
<p>I've learned that there seem to be two ways to create/use a SQL database with this application. </p>
<p>The first seems to be where from within C#, I can create a "local database" by right-clicking on my application in the Solution Explorer and clicking "Add"->"New Item"->"Local Database". Then it's shown in the Database Explorer and I can use it. </p>
<p>The other way is where I create a database with SQL Server Management Studio and then from within the C# code, I open a connection to it (SQLConnection... yada yada yada) and use it.</p>
<p>I'm having a hard time understanding what technical reasons there are between choosing one way or the other way to do this...</p>
<p>Can someone describe the differences and what criteria would be used to choose one way vs. the other? (or point to a website reference...)</p>
<p>Thanks!</p>
<p>-Adeena </p>
<p>Additional Info...
Right now, this is really a hobby project as I get a few things worked out.</p>
<ol>
<li>I'm the only developer and working on a single machine </li>
<li>The application is intended to be one that runs standalone - not in a
browser or over the web in any way. I know that that's not the direction
the universe is heading, but as mentioned above, this is a hobby
project that I need to complete to work out a few other issues. </li>
<li>I don't believe I have any need or intent for multiple applications to
work on this database.</li>

replace column values in one dataframe by values of another dataframe | <p>I have two dataframes, the first one has 1000 rows and looks like:</p>

2011-09-10 bbbj-1Y_jn Fantol 431
2011-11-02 hsgç_T2 Gondow 569
</code></pre>
<p>The column <code>Group</code> has different values, sometimes repeated, but in general about 50 unique values.</p>
<p>The second dataframe contains all these 50 unique values (50 rows) and also the hotels, that are associated to these values:</p>
<pre><code>Group Hotel
tri23_1 Jamel
hsgç_T2 Frank
bbbj-1Y_jn Luxy
mlkl_781 Grand Hotel
vchs_94 Vancouver
</code></pre>
<p>My goal is to replace the value in the column <code>Group</code> of the first dataframe by the corresponding values of the column <code>Hotel</code> of the second dataframe/or create the column <code>Hotel</code> with the corresponding values. When I try to make it just by assignment like</p>
<pre><code>df1.loc[(df1.Group=df2.Group), 'Hotel']=df2.Hotel

<p>I have an error that the dataframes are not of equal size, so the comparison is not possible.</p> | 0 |

converting QdateTime to normal python dateTime? | <p>I have a lot of existing code that just uses the normal <code>dateTime</code> class in python, however in upgrading my program I am using the <code>QtGui.QdateTimeEdit()</code> class, but that class returns a <code>QdateTime</code> object that seems to be incompatible with the normal <code>dateTime</code> object. </p>
<p>So, is there a sane way to convert <code>QdateTime</code> to normal python <code>dateTime</code>? Other then breaking it into its parts and recreating a normal <code>dateTime</code> object from that? I am using PyQt4 with Python 3.2. Thanks.</p> | 0 |

Why does Request.Cookies return string instead of HttpCookie object in foreach loop? | <p>This morning I accidentally saw the following snippet code, I was fairly surprised because it work very well.</p>
<p>Don't look at its logic please, I'm just curious why does the HttpCookieCollection (Request.Cookies in this case) return a string (cookie name) instead of a HttpCookie object in foreach loop. Is it a consistency issue because we normally get HttpCookie object in this collection by index/name?</p>
<p>Thanks,</p>
<pre><code>foreach (string cookieKey in System.Web.HttpContext.Current.Request.Cookies)
{
HttpCookie tmpCookie = System.Web.HttpContext.Current.Request.Cookies[cookieKey];
if (tmpCookie != null && tmpCookie["RecentlyVisited"] != null)
{
cookie.Add(tmpCookie);
}

Can I use JavaScript to create a client side email? | <p>I want to create a client side mail creator web page. I know the problems of using the mailto action in an html form (not standard, no default mail appication set on the client). But the web page isn't very important, and they don't care very much.</p>
<p>The mail created by the mailto action has the syntax:</p>
<blockquote>
<p>subject: undefined subject<br>
body:</p>
<p>param1=value1<br>
param2=value2<br>
.<br>
.<br>
.<br>
paramn=valuen </p>
</blockquote>
<p>Can I use JavaScript to format the mail like this?</p>
<blockquote>
<p>Subject:XXXXX</p>
<p>Body:
Value1;Value2;Value3...ValueN</p>

How to configure git to avoid accidental git push | <p>After git clone, the config in the new repo looks like:</p>
<pre><code>remote.origin.url=<some url>
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*
branch.master.remote=origin
branch.master.merge=refs/heads/master
</code></pre>
<p>Then, I can execute "git pull" and "git push". But I'm interested in only do "git pull", because I want to push into another repo.</p>
<p>One thing I can do is:</p>
<pre><code>git add remote repo-for-push <some other url>
git push repo-for-push master
</code></pre>
<p>But I would like to configure git to use default and distinct repositories for pull and push, i.e:</p>
<pre><code>git pull # pulls from origin
git push # pushes into repo-for-push, avoiding accidental push into the origin
</code></pre>
<p>How can this be configured?
Thanks in advance.</p>
<p>EDIT:<br>
Basically, I want to setup the default push repo to be different from the default fetch/pull repo.</p> | 0 |
DefaultCredentials in Accessing CRM / Sharepoint Web Services | <p>I made an application that access CRM's web service. The problem is, when I deployed the dll into Sharepoint server, it returned error 401 unauthorized. Apparently the System.Net.CredentialCache.DefaultCredentials didn't work (my suspicion). Here's the code.</p>
<pre><code>CrmSdk.CrmAuthenticationToken token = new CrmSdk.CrmAuthenticationToken();
token.AuthenticationType = AuthenticationType.AD;
token.OrganizationName = ORGANIZATION_NAME;
CrmService service = new CrmService();
service.Url = "http://crmserver:5555/mscrmservices/2007/crmservice.asmx";
service.CrmAuthenticationTokenValue = token;
service.PreAuthenticate = true;
service.Credentials = System.Net.CredentialCache.DefaultCredentials;
</code></pre>
<p>It goes vice-versa.</p>
<p>When I made application that access Sharepoint's webservice (coding the plugin) and deployed it to CRM server. It couldn't access the Sharepoint's web service. Unauthorized error. Here is the code:</p>
<pre><code>Lists listService = new Lists();
listService.PreAuthenticate = true;
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
listService.Url = "http://sharepointserver/webname/_vti_bin/Lists.asmx";
</code></pre>
<p>My CRM server and Sharepoint server are in the same domain.</p>
<p>For both code, if I changed the credentials part into something like this then deploy it on server, it can run.</p>
<pre><code>service.Credentials = new NetworkCredential("username", "password", "domain");
</code></pre>
<p>Still, I don't want to do this because it reveals user's password in the code. May anyone help me?</p>
<p>The IIS in both server doesn't allow Anonymous Access and it uses Integrated Windows Authentication. </p>
<p>Thank you</p>
<hr>
<p>From my local computer, I can access the CRM web services or Sharepoint web services. I guess I'm authorized because the DefaultCredentials sent my credentials that its password is saved in the "<strong>Stored Username and Password</strong>" (<em>Control Panel > User Accounts > tab Advanced > Manage Passwords</em>)
This way, I don't have to type:</p>
<pre><code>service.Credentials = new NetworkCredential("username", "password", "domain");
</code></pre>
<p>and my DefaultCredentials from my local comp is authorized to access the web services.</p>
<p>I tried to implement this on the Sharepoint server that access CRM web services. and..tadaa..it won't work. hahaha.. </p>
<p>can we inject credentials to DefaultCredentials in server?</p>
<p>the last thing I want to do is to hardcode the useraccount (like the code above)</p> | 0 |
Python decorators: how to use parent class decorators in a child class | <p><strong>Note</strong>:</p>
<p><em>The accepted answer on the other question shows how to use the parent decorater.</em></p>
<p><em>The accepted answer on this question shows moving the decorator to the module scope.</em></p>
<hr>
<p>EDIT: Using the previous example was a bad idea. Hopefully this is more clear:</p>
<pre><code>class A:
def deco( func ):
print repr(func)
def wrapper( self, *args ):
val = func( *args )
self.do_something()
return val
return wrapper
def do_something( self ):
# Do something
print 'A: Doing something generic for decoration'
@deco
def do_some_A_thing ( self ):
# Do something
print 'A: Doing something generic'
class B ( A ):
@deco
def do_some_B_thing( self ):
# Do something
print "B: Doing something specific"
a = A()
b = B()
a.do_some_A_thing()
b.do_some_B_thing()
#Expected Output:
#A: Doing something generic
#A: Doing something generic for decoration
#B: Doing something specific
#A: Doing something generic for decoration
</code></pre>
<p>This code generates a NameError: name 'deco' is not defined inside B.
The decorator needs to be inside the class scope because I require access to stored state. </p>
<p>Third Edit: On Sven's suggestions, I tried this:</p>
<pre><code>class A:
def deco( func ):
def wrapper( self, *args ):
val = func( *args )
self.do_something(*args)
return val
return wrapper
def do_something( self ):
# Do something
print 'A: Doing something generic for decoration'
@deco
def do_some_A_thing ( self ):
# Do something
print 'A: Doing something generic'
deco = staticmethod(deco)
class B ( A ):
@A.deco
def do_some_B_thing( self ):
# Do something
print "B: Doing something specific"
a = A()
b = B()
a.do_some_A_thing()
b.do_some_B_thing()
#Expected Output:
#A: Doing something generic
#A: Doing something generic for decoration
#B: Doing something specific
#A: Doing something generic for decoration
</code></pre>
<p>I now have have TypeError: do_some_A_thing() takes exactly 1 argument (0 given). Any pointers?</p> | 0 |
New Project: Ruby on Rails or Symfony2 ( or other framework) | <p>I am about to start a new project and I am hung up on which language/framework to use. I've been a PHP programmer professionally, but it wasn't on the scale of this project. I've played around with RoR and i've been very impressed so far. Right now, the two leading candidtates are RoR and Symfony2.</p>
<p>My major hang ups with RoR:
- i don't know ruby, or i hardly do. i can read it ok, but get stuck writing the code.
- i've read complaints about it being slow, and it seems to be slow just at the CLI.</p>
<p>My major hang ups with Symfony2:
- there's practically no documentation for it. Symfony1.x? sure..but not symfony2
- there's also little support. the BB on their site is like 80% spam.
- went to install it on a local dev enviroment haven't been able to even get that running (see my first hang up)</p>
<p>this project will be fairly complex and go beyond the basic CRUD operations. it isn't under a super-tight timeline, but there is one. ~3 months for milestone1 which is basically a calendar, some financial organization stuff (not transactions with financial institutions, just personal finance organization type stuff), and a project manager/cms.</p>
<p>also, i'm open to using other frameworks, but symfony2 seems to be the best right now. if symfony2 had RoR's support/documentation/tutorials/etc it would be a no brainer.</p>
<p>i'm really interested in hearing what the stackoverflowverse has to say on the matter. im constantly impressed with the quality of the answers/replies on this site. </p>
<p>some other sub-questions (that are in my head right now):
- if you recommend a different php framework, why?
- what are you biggest gripes with any of the options mentioned?</p>
<p>i know CakePHP is the closest to RoR, but i've been reading that the models are a bit wonky (Many to many relationships and such).</p>
<p>right now, i'm leaning towards RoR. Simply put, i really want to learn it and it could do the job. i just don't know ruby and i've ready a lot of good about symfony2.</p>
<p>any advice you could offer will be greatly appreciated. thanks!</p> | 0 |

2 different types of custom UITableViewCells in UITableView | <p>in my UITableView i want to set for the first news of an rss feed a custom tableViewCell(Type A lets say) and for the other news second, third etc.. another custom tableViewCell(trype B) the problem is that the custom tableViewCell(trype A) created for the first news is reused, but curiously the number of rows between the first use of the customViewCell(type A) and the second appearance of the same type of customViewCell is not equal..</p>

<pre><code>- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

Database design for a survey | <p>I need to create a survey where answers are stored in a database. I'm just wondering what would be the best way to implement this in the database, specifically the tables required. The survey contains different types of questions. For example: text fields for comments, multiple choice questions, and possibly questions that could contain more than one answer (i.e. check all that apply).</p>
<p>I've come up with two possible solutions:</p>
<ol>
<li><p>Create a giant table which contains
the answers for each survey
submission. Each column would
correspond to an answer from the
survey. i.e. SurveyID, Answer1,
Answer2, Answer3</p>
<p>I don't think this is the best way
since there are a lot of questions
in this survey and doesn't seem very
flexible if the survey is to change.</p></li>
<li><p>The other thing I thought of was
creating a Question table and Answer
table. The question table would
contain all the questions for the
survey. The answer table would contain
individual answers from the survey,
each row linked to a question.</p>
<p>A simple example:</p>
<p><strong>tblSurvey</strong>: SurveyID</p>
<p><strong>tblQuestion</strong>: QuestionID, <em>SurveyID</em>, QuestionType, Question </p>
<p><strong>tblAnswer</strong>: AnswerID, <em>UserID</em>, <em>QuestionID</em>, Answer</p>
<p><strong>tblUser</strong>: UserID, UserName</p>
<p>My problem with this is that there
could be tons of answers which would
make the Answer table pretty huge.
I'm not sure that's so great when it
comes to performance.</p></li>
</ol>
<p>I'd appreciate any ideas and suggestions.</p> | 0 |

Python 3, module 'itertools' has no attribute 'ifilter' | <p>I am new at Python, trying to build an old python file into Python 3. I got several build errors which I solved. But at this point I am getting above error. I have no idea how to fix this. The code section looks like below.</p>

django admin many-to-many intermediary models using through= and filter_horizontal | <p>This is how my models look:</p>
<pre><code>class QuestionTagM2M(models.Model):
tag = models.ForeignKey('Tag')
question = models.ForeignKey('Question')
date_added = models.DateTimeField(auto_now_add=True)
class Tag(models.Model):
description = models.CharField(max_length=100, unique=True)
class Question(models.Model):
tags = models.ManyToManyField(Tag, through=QuestionTagM2M, related_name='questions')
</code></pre>
<p>All I really wanted to do was add a timestamp when a given manytomany relationship was created. It makes sense, but it also adds a bit of complexity. Apart from removing the .add() functionality [despite the fact that the only field I'm really adding is auto-created so it technically shouldn't interfere with this anymore]. But I can live with that, as I don't mind doing the extra <code>QuestionTagM2M.objects.create(question=,tag=)</code> instead if it means gaining the additional timestamp functionality. </p>
<p>My issue is I really would love to be able to preserve my <code>filter_horizontal</code> javascript widget in the admin. I know the docs say I can use an inline instead, but this is just too unwieldy because there are no additional fields that would actually be in the inline apart from the foreign key to the <code>Tag</code> anyway. </p>
<p>Also, in the larger scheme of my database schema, my <code>Question</code> objects are already displayed as an inline on my admin page, and since Django doesn't support nested inlines in the admin [yet], I have no way of selecting tags for a given question. </p>
<p>Is there any way to override <code>formfield_for_manytomany(self, db_field, request=None, **kwargs)</code> or something similar to allow for my usage of the nifty <code>filter_horizontal</code> widget and the auto creation of the <code>date_added</code> column to the database? </p>
<p>This seems like something that django should be able to do natively as long as you specify that all columns in the intermediate are automatically created (other than the foreign keys) perhaps with <code>auto_created=True</code>? or something of the like</p> | 0 |

<li>go to ActionBarSherlock folder, run "android update <strong>lib-project</strong> --path ."</li>
<li>go to ViewPagerTabs folder, run "android update <strong>lib-project</strong> --path ." too</li>
<li>go to app folder, run "android update <strong>project</strong> --path ."</li>
<li>run "and debug" under app folder, and I got following errors:</li>
</ol>
<p>:</p>
<pre><code>[javac] C:\Android\TestApp\src\com\test\App\TestActivity.java:46: cannot find symbol
[javac] symbol : method getSupportActionBar()
[javac] location: class com.test.App.TestActivity
[javac] final ActionBar ab = getSupportActionBar();
[javac] ^
</code></pre>
<p>So question NO. 1: <strong>I have correct library references in app's project.properties, and ActionBarSherlock & ViewPagerTabs could be built successfully, why do I still get these errors?</strong></p>
<p>There's a workaround for this issue -- copy all classes.jar under library's bin folder into app's libs folder, and run "ant debug" again. But I need to delete these .jar files under app's libs folder after all .java files of app could be compiled.</p>
<p>Running "ant debug" again after this, I will get following errors:</p>

nodejs write 64bit unsigned integer to buffer | <p>I want to store a 64bit (8 byte) big integer to a nodejs buffer object in big endian format.</p>
<p>The problem about this task is that nodejs buffer only supports writing 32bit integers as maximum (with buf.write32UInt32BE(value, offset)). So I thought, why can't we just split the 64bit integer?</p>
<pre><code>var buf = new Buffer(8);
buf.fill(0) // clear all bytes of the buffer
console.log(buf); // outputs <Buffer 00 00 00 00 00 00 00 00>
var int = 0xffff; // as dezimal: 65535
buf.write32UInt32BE(0xff, 4); // right the first part of the int
console.log(buf); // outputs <Buffer 00 00 00 00 00 00 00 ff>
buf.write32UInt32BE(0xff, 0); // right the second part of the int
console.log(buf); // outputs <Buffer 00 00 00 ff 00 00 00 ff>
var bufInt = buf.read32UInt32BE(0) * buf.read32UInt32BE(4);
console.log(bufInt); // outputs 65025
</code></pre>
<p>As you see this nearly works. The problem is just splitting the 64bit integer and finding the missing 510 at reading it. Would somebody mind showing the solutions for these two issues?</p> | 0 |

How to share redux store in micro frontend architecture? | <p>I am trying to create a small project to implement micro-frontend architecture following <a href="https://martinfowler.com/articles/micro-frontends.html" rel="noreferrer">Micro Frontends</a> article. I am creating multiple repositories for each MFE(Micro frontend) and also using Redux for the application. I have the following architecture:</p>
<ol>
<li><code>Frame</code> - A centralised(main) repo that is responsible for rendering the main application part and MFEs based on routing(I am using <code>connected-react-router</code>). It initialises the Redux store and also adds an <code>injectReducer</code> function to dynamically add reducers as explained in <a href="https://redux.js.org/recipes/code-splitting#defining-an-injectreducer-function" rel="noreferrer">code splitting in redux</a> docs. The frame fetches the manifest for particular MFE and renders it. The frame also has some redux data for authentication purpose.</li>
<li><code>MFEs</code> - These are the individual feature-wise application and are rendered by frame.</li>
</ol>
<p>Now I have a problem that I want to use <code>injectReducer</code> function into my MFEs to dynamically add reducers to store. For this, I need access to the same <code>store</code> instance that is created by frame.
As mentioned in <a href="https://stackoverflow.com/questions/38460949/what-is-the-best-way-to-access-redux-store-outside-a-react-component">this answer</a>, the ideal way is to export the created store instance and use it but how we can share the same instance of the store across multiple repos?</p> | 0 |

Forward HTTPS traffic thru Nginx without SSL certificate | <p>I want to use Nginx to expose my NodeJS server listening on port 443.</p>
<p>I don't want to manage the SSL certificate with Nginx. I would rather do that on the NodeJS server using the <code>SNICallback</code> option of <code>https.createServer</code>.</p>
<p>How do I setup the <code>nginx.conf</code> to support this?</p> | 0 |
Elixir - Looping through and adding to map | <p>I'm rebuilding something in Elixir from some code I built in C#.</p>
<p>It was pretty hacked together, but works perfectly (although not on Linux, hence rebuild).</p>
<p>Essentially what it did was check some RSS feeds and see if there was any new content. This is the code:</p>
<pre><code>Map historic (URL as key, post title as value).
List<string> blogfeeds
while true
for each blog in blogfeeds
List<RssPost> posts = getposts(blog)
for each post in posts
if post.url is not in historic
dothing(post)
historic.add(post)
</code></pre>
<p>I am wondering how I can do Enumeration effectively in Elixir. Also, it seems that my very process of adding things to "historic" is anti-functional programming.</p>
<p>Obviously the first step was declaring my list of URLs, but beyond that the enumeration idea is messing with my head. Could someone help me out? Thanks.</p> | 0 |

Handling X-FORWARDED-PROTO header in Java web application | <p>Can any one guide me in working with <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-Proto" rel="nofollow noreferrer">X-FORWARDED-PROTO</a> header in Java web application deployed to Apache Tomcat.</p>
<p>The application setup is in such a way that tomcat talks with Apache webserver, which in turn talks with Cisco Load Balancer, finally the balancer publishes the pages to the client (tomcat -> apache2 -> load balancer -> client).</p>
<p>The SSL Certificate is installed in Load Balancer and it's handling HTTPS requests. My requirement is to make the application behave in such a way that it uses the <em>X-FORWARDED-PROTO</em> and change the pages as HTTP or HTTPS.</p>
<p>Checking on the header files of my webpages I could not find the <em>X-FORWARDED-PROTO</em> header. I don't have access to the Load Balancer configuration either, and the IT has suggested us to use the <em>X-FORWARDED-PROTO</em> to differentiate between HTTP and HTTPS request.</p>
<p>Is there any configuration to be done in Tomcat or Apache level so that it will return the <em>X-FORWARDED-PROTO</em> header? Or is it that the configuration should be handled in Load Balancer?</p> | 0 |

Flip ordering of legend without altering ordering in plot | <p>I have found that when adding <code>coord_flip()</code> to certain plots using ggplot2 that the order of values in the legend no longer lines up with the order of values in the plot.</p>
<p>For example:</p>
<pre><code>dTbl = data.frame(x=c(1,2,3,4,5,6,7,8),
y=c('a','a','b','b','a','a','b','b'),
z=c('q','q','q','q','r','r','r','r'))
print(ggplot(dTbl, aes(x=factor(y),y=x, fill=z)) +
geom_bar(position=position_dodge(), stat='identity') +
coord_flip() +
theme(legend.position='top', legend.direction='vertical'))
</code></pre>
<p><img src="https://i.stack.imgur.com/bNwCU.png" alt="enter image description here"></p>
<p>I would like the 'q' and 'r' in the legend to be reversed without changing the order of 'q' and 'r' in the plot.</p>
<p><code>scale.x.reverse()</code> looked promising, but it doesn't seem to work within factors (as is the case for this bar plot).</p> | 0 |
