John Ruiz, Software Engineer: December 2013
http://blog.johnruiz.com/2013_12_01_archive.html
John Ruiz, Software Engineer. Sometimes, there is code. You have to compile the code. Tuesday, December 17, 2013. Configure a FIPS 140-2 Compliant Java Provider on RedHat/CentOS/Fedora. If you're using any form of cryptography in Java, you might be aware of NIST FIPS 140-2, which lays out what you can and cannot use on federal information processing systems. Oracle documentation, true to form, only gets you 80% of the way there. Here's their technical notes on FIPS 140 compliance. Anyway, in the picture ...
John Ruiz, Software Engineer: Invalid provider type specified when accessing X509Certificate2.PrivateKey
http://blog.johnruiz.com/2012/01/invalid-provider-type-specified-when.html
John Ruiz, Software Engineer. Sometimes, there is code. You have to compile the code. Tuesday, January 10, 2012. Invalid provider type specified when accessing X509Certificate2.PrivateKey. Today, I was attempting to digitally sign a byte array with my private key so that I could produce an event on the event bus and a consumer could ensure that the message came from me and was not modified while in transit. Public byte[] SignData(byte[] data). CertStore.Open(OpenFlags.ReadOnly);. It turns out that by usi...
John Ruiz, Software Engineer: Installing CouchDB 1.2 on CentOS 6
http://blog.johnruiz.com/2012/04/installing-couchdb-12-on-centos-6.html
John Ruiz, Software Engineer. Sometimes, there is code. You have to compile the code. Thursday, April 12, 2012. Installing CouchDB 1.2 on CentOS 6. CouchDB has a really great idea behind it. Whether or not CouchDB delivers on it, I've been wanting to discover for a while. Only way to do that is kick the tires, so I started the process of figuring out how to install it. CouchDB runs on erlang, so you need to install erlang from the EPEL. Now you can install erlang:. Sudo yum install erlang. Under the [htt...

John Ruiz, Software Engineer: Windows does not always honor DNS order
http://blog.johnruiz.com/2011/12/windows-does-not-always-honor-dns-order.html
John Ruiz, Software Engineer. Sometimes, there is code. You have to compile the code. Wednesday, December 21, 2011. Windows does not always honor DNS order. I was having a problem where some internal server names would become unresolvable after being resolvable. After becoming tired of flushing the dns resolver cache, I finally opened wireshark to see what was going on. To my surprise, windows was using my secondary DNS (8.8.8.8) instead of my primary, internal DNS! And then click OK. Menu, point to New.

Getting Cirrius: Calculating Similarity (Part 1): Cosine Similarity
http://www.gettingcirrius.com/2010/12/calculating-similarity-part-1-cosine.html
Meandering thoughts about technology and management. Sunday, December 5, 2010. Calculating Similarity (Part 1): Cosine Similarity. Dot Product, 2010). Cosine similarity is literally the angular difference between two vectors. Cosine Similarity is expressed by the formula:. Cosine Similarity, 2010). For those of you allergic that don't speak "mad mathematician" (like me), to calculate the cosine similarity, we need to:. Take the dot product of vectors A and B. Calculate the magnitude of Vector A. In the c...
Getting Cirrius: What I'm Reading
http://www.gettingcirrius.com/p/what-im-reading.html
Meandering thoughts about technology and management. I spend a lot of time reading (that's probably an understatement). Right now my current interests in computing span a number of subjects: architecture, alternative languages on the JVM, Ruby, Node.js, CoffeeScript, the Apache Hadoop ecosystem, NoSQL, State Machines, Complex Event Processing, Rules Engines, and Event-Driven Architectures. Getting Started with Google Guava. 40 out of 5.0. 25 out of 5.0. I have to first say that the I was mislead by the t...
Getting Cirrius: November 2013

Meandering thoughts about technology and management. Sunday, November 17, 2013. Configure IPTables with Ansible. If you need to configure IPTables on the fly using Ansible, this is a really quick way to do it (and requires no extra dependencies). This mechanism relies on the lineinfile. Module, which allows you to idempotently add/verify/remove lines of text inside a file. I then use with items. And list all of the protocols and ports I want available on the box.

Getting Cirrius: June 2014

Meandering thoughts about technology and management. Thursday, June 19, 2014. I will no longer be using Blogger as my platform. There are some things to like about the platform, but more and more I find it to be suboptimal, particularly for developers who want to post code. I won't be closing the site down, but I do plan to not write any more content within Blogger. You can view my new blog at http:/ rclayton.silvrback.com. Friday, June 13, 2014.

Getting Cirrius: October 2012
http://www.gettingcirrius.com/2012_10_01_archive.html
Meandering thoughts about technology and management. Friday, October 12, 2012. Convert Lat, Lon to MGRS (vice versa) in Java. Need to convert between MGRS and Latitude, Longitude pairs in Java. There are a couple of libraries out there, but they have unfriendly open source licenses (no redistribute unless your project is same license, requires commercial license in production, etc.). On the other hand, the World Wind project has a very nice license: NASA Open Source Agreement v1.3. 2 Attribute the code.
Getting Cirrius: February 2013
http://www.gettingcirrius.com/2013_02_01_archive.html
Meandering thoughts about technology and management. Sunday, February 10, 2013. Integrating Spring Security with Dropwizard. Dropwizard is a great framework for streamlining Java web apps (I'd argue any app) for deployment in a production environment. It's an answer to the complexity of Java Web and Application Containers, which tend to be overkill for 90% of your use-cases. In our JAX-RS controllers. To use our set of extensions, follow the instructions below:. ROLE USER, ROLE ADMIN". Initialize your Sp...
Getting Cirrius: Enable JMX on Amazon EC2
http://www.gettingcirrius.com/2014/06/enable-jmx-on-amazon-ec2.html
Meandering thoughts about technology and management. Friday, June 13, 2014. Enable JMX on Amazon EC2. I ran into an issue this last week enabling JMX for a Java process on an Amazon EC2 instance. After a couple of hours researching (and finding a couple of answers on StackOverflow), I wanted to share a complete answer to how this is done. 1 Unblock RMI and JMX Ports. 2 Resolve the Public DNS Name of your EC2 Instance. 3 Prefer the IPv4 Stack. Finally, the last issue we ran into was the JMX server binding...

Meandering thoughts about technology and management. Sunday, June 10, 2012. Securing Node.js and Express with SSL Client-Authentication. In the course of my work using Node.js, I did some research on implementing securing Node.js. There are a couple of decent articles on the subject, and of course a number of frameworks that performed this work, but nothing I read or evaluated really quite fit my needs:. In my case, I preferred certificate-based (SSL). Remain as unobtrusive as possible. The first step to...

Saturday, November 22, 2014. Finally we get to the real meat. How do I actually create that bloody web site? As mentioned before, I've chosen to go with Google's AppEngine because it's free, hosted by default and easy to get started with. That doesn't mean we don't have to work for it, but the work mostly makes sense and the learning curve manageable. Udacity gives you a big bang course on the whole stack with its ' Web Development. The web server webapp2. Itself is a standard component so feel free to r...

Python: Check if Import/Dependency is Available at Runtime. At work, we have an internal python package that is written to accomodate synchronous AND asyncronous HTTP requests with the requests and tornado packages respectively. However, a nuanced detail about this is that we don’t install either of these dependencies when consumers install and use our package. Https:/ gist.github.com/strife25/432c8354d293d1ad4713. Now, our developers can have their programs fail fast and fix this problem quickly! Proble...
