36,006,029 | Disabling Spring Security headers does not work | <p>I need to disable the cache control headers in my Spring Security conf.</p>
<p>According to the documentation a simple <code>http.headers.disable()</code> should do it, but I still see the</p>
<pre><code>Cache-Control:no-cache, no-store, max-age=0, must-revalidate
Expires:0
Pragma:no-cache
</code></pre>
<p>headers in responses.</p>
<p>My current security config is:</p>
<pre><code>http.antMatcher("/myPath/**") // "myPath" is of course not the real path
.headers().disable()
.authorizeRequests()
// ... abbreviated
.anyRequest().authenticated();
</code></pre>
<p><strong>Things I've tried so far:</strong></p>
<p><strong>application.properties</strong></p>
<p>I added the <code>security.headers.cache=false</code> line, but that made no difference.</p>
<p><strong>Using a filter</strong></p>
<p>I tried the following filter:</p>
<pre><code>@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
chain.doFilter(request, new HttpServletResponseWrapper((HttpServletResponse) response) {
@Override
public void setHeader(String name, String value) {
if (name.equalsIgnoreCase("Cache-Control")) {
value = "";
} else if (name.equalsIgnoreCase("Expires")) {
value = "";
} else if (name.equalsIgnoreCase("Pragma")) {
value = "";
}
super.setHeader(name, value);
}
});
}
</code></pre>
<p>After adding logging I saw that this filter only writes the <code>X-XSS-Protection</code> header, all the cache headers are written somewhere later and this filter doesn't have access to "override" them. This happens even if I add this filter at the last position of the security filter chain.</p>
<p><strong>Using an interceptor</strong></p>
<p>I tried the following interceptor:</p>
<pre><code>@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
String requestUri = request.getRequestURI();
response.setHeader("Cache-Control", "max-age=3600");
response.setHeader("Expires", "3600");
response.setHeader("Pragma", "");
}
</code></pre>
<p>This (quite predictably) just added the headers, meaning that the original <code>no-cache</code> headers still appear in addition to the ones added by the interceptor.</p>
<p>I'm at my wits end here. How do I get rid of the cache control header set by Spring security?</p>

36,007,686 | How to parse a csv that uses ^A (i.e. \001) as the delimiter with spark-csv? | <p>Terribly new to spark and hive and big data and scala and all. I'm trying to write a simple function that takes an sqlContext, loads a csv file from s3 and returns a DataFrame. The problem is that this particular csv uses the ^A (i.e. \001) character as the delimiter and the dataset is huge so I can't just do a "s/\001/,/g" on it. Besides, the fields might contain commas or other characters I might use as a delimiter.</p>
<p>I know that the spark-csv package that I'm using has a delimiter option, but I don't know how to set it so that it will read \001 as one character and not something like an escaped 0, 0 and 1. Perhaps I should use hiveContext or something?</p>

36,009,725 | Swift sometimes calls wrong method | <p>I noticed strange behaviour during working with Swift projects. I can't explain it other than Swift sometimes calls wrong method. It is very rare and even adding blank lines to the code could lead that this error is gone.</p>
<p>Let me explain in screenshots what I mean, next I use CoreData example of SwiftDDP project that can be found on Github, but such issues I was able to see in my own projects.</p>
<p>Here we at <code>Todos.swift:74</code> where you can see breakpoint, I expect that next call should be <code>getId()</code> method of <code>MeteorClient</code> class because it was already instantiated:</p>
<p><a href="https://i.stack.imgur.com/7F4mM.png" rel="noreferrer"><img src="https://i.stack.imgur.com/7F4mM.png" alt="Screenshot 1"></a></p>

<p><a href="https://i.stack.imgur.com/mMsDg.png" rel="noreferrer"><img src="https://i.stack.imgur.com/mMsDg.png" alt="Screenshot 2"></a></p>

<p><a href="https://i.stack.imgur.com/SGdYE.png" rel="noreferrer"><img src="https://i.stack.imgur.com/SGdYE.png" alt="Screenshot 3"></a></p>
<p>In my project I saw this issue fairly often before I stopped using singletons, so it could be related to Swift static memory usage or I don't understand something that is not surprising as I have little experience with multithreading and memory management.</p>
<p>My environment is:</p>
<ul>
<li>AppCode OC-145.184.11</li>
<li>Xcode Version 7.2.1 (7C1002)</li>
<li>iOS 9.2 SDK</li>
<li>Apple Swift version 2.1.1 (swiftlang-700.1.101.15 clang-700.1.81)</li>
</ul>
<p><strong>NOTE</strong>: Here I use AppCode but the same behavior I was able see in Xcode, and even more if the same issue that reproduces in Xcode could not reproduce in AppCode and vice versa.</p>
<p>Would be thankful if someone can explain this strange behaviour to me.</p>

36,011,595 | Docker named volumes vs DOC (data-only-containers) | <p>Up to recent version of Docker (v1.10), we were thought that we can use DOC: <em>data-only containers</em>. So I would create such DOC (based on e.g. busybox) and use <code>--volumes-from</code> to link it to my container. You can still read about this in <a href="https://docs.docker.com/engine/userguide/containers/dockervolumes/#creating-and-mounting-a-data-volume-container">Docker documentation</a>.</p>
<p>With new version of docker, it is said that instead of DOC we should use <code>named volumes</code>. Here is an example of <code>docker-compose.yml</code>:</p>
<pre><code>version: '2'
services:
elasticsearch:
image: elasticsearch:2.2.0
command: elasticsearch -Des.network.host=0.0.0.0
ports:
- "9201:9200"
volumes:
- "es-data:/usr/share/elasticsearch/data"
volumes:
es-data:
</code></pre>
<p>Here we created and use named volume <code>es-data</code>.</p>
<p>There is still not much documentation on this new feature. I am asking:</p>
<ul>
<li>Can we replace DOC with named containers? How long volume is persisted? What if I remove the container that is using it?</li>
<li>How can we e.g. backup now? Previously, I could <code>docker run --rm --volumes-from es-data ...</code> and then <code>tar</code> it.</li>

<p>My question is, given .NET has been with us for about 13 years, why should I <strong><em>ever</em></strong> have to use the native API aka P/Invoke? Why hasn't everything been converted to official .NET managed assemblies?</p>

The keyboard is always faster (for me), yet there is no standard Windows keyboard shortcut for it. So great, a very simple C# program for me to write. Imagine my surprise when I found I would have to dip into the native API to this. I remember having to do this in the early days of .NET --sure, a new technology needs a few years to catch up, right? Well now it's 2016. </p>

<p>What I've tried:</p>
<p><strong><a href="https://www.npmjs.com/package/node-mongo-seeds" rel="noreferrer">node-mongo-seed</a></strong>; Pretty straight forward, but consistently throws errors on the end of arrays. (Perhaps the missing bson module is at fault?)</p>

<p><strong><a href="https://www.npmjs.com/package/mongoose-seed" rel="noreferrer">mongoose-seed</a></strong>; Also pretty straight forward, basically puts the JSON objects into a variable before exporting to the database. Promising, but... more errors...</p>

attributes: [String],
coordinates: {type: [Number], index: '2dsphere'},

<p>Creating package and installing from S3 work fine. There is only one issue here: we will release new code and give them different versions. If we host our code on Pypi, you can upgrade some packages to their newest version by calling "pip install package --upgrade". </p>
<p>But if you host your packages on S3, how do you let pip know there's a newer version exists? How do you roll back to an older version by simply giving pip the version number? Is there a way to let pip know where to look for different version of wheels on S3?</p>

<pre><code>if(arr1[i][j] != arr2[i][j])
</code></pre>
<p>The problem is, as far as I can tell, my program shouldn't be entering the enclosing for-loop where this line is located to begin with. It should return false at this point:</p>
<pre><code>if(arr1[i] == null || arr2[i] == null) //one is null
return false;
</code></pre>
<p>What am I doing wrong here? Thank you.</p>
