Connecting via SSL in Android. Correctly and securely. Mimic browser functionality with untrusted certs and hostname mismatches Okay, for those of you who’ve been waiting, this is the blog. For those who haven’t, welcome, we’re going to talk about https connections (specifically) on Android (TM) from within a native app and connecting to sites that Android views as possible security risks. Easy like learning to drive if your face was in your navel. But I’ve tried to make the issues and the code as clean and clear as possible for you. Hope it is of some assistance. I’m going to take it slow and address all of the issues, even the seemingly unrelated ones. My goal with this blog is to help those who are just getting started on Android too, so I’ll use a lot of headings, giving you the chance to skip sections you are already familiar with. Otherwise, grab a cup of co... (more)

All-Consuming, All-Confusing

Ask two politically opposed people in any given country about the causes of the country’s problems, and guess what? Each will give you an answer filtered through their world-view. Through what they know, and what they believe. That is not to say one is right and one is wrong, both simply see things in the manner their background and experiences tell them is right. We definitely live in interesting times. Server virtualization has just about reached saturation, application development is going through a wide range of changes from the return of automated testing to continuous integr... (more)

The Storage Future Is Cloudy, and It's About Time

One of the things I have talked about quite a bit in the last couple of months is the disjoint between the needs of enterprise IT and the offerings of a wide swath of the cloud marketplace. Some times it seems like many cloud vendors are telling customers “here’s what we choose to offer you, deal with it”. Problem is, oftentimes what they’re offering is not what the enterprise needs. There are of course some great examples of how to do cloud for the enterprise, Rackspace (among others) has done a smashing job of offering users a server with added services to install a database o...

Cloud Database – Are You Prepared?

The ongoing saga of everything cloud is entertaining, if nothing else. I have a couple of areas of interest that aren’t really burning up the electrons, one of them is cloud databases. Let’s face it, while “the cloud” is interesting in an application sense, for IT it is relatively useless without the ability to access databases. Normally databases housed in your internal IT department. Of course internal “private” clouds will address much  of this issue, until they are readily available, we are faced with the reality that we have to find a solution we can trust to house data that...

Mainframes Are Dead, Right?

Funny thing about the hype cycle in high tech, things rarely turn out the way cheerleaders proclaim it will. Mainframes did not magically disappear in any of the waves that predicted their demise. The reason is simple – there is a lot of code running on mainframes that works, and has worked well for a long time, rewriting all of that code would be a monumental undertaking that, even today, twenty years after the first predictions of its demise, many organizations – particularly in financials - are not undertaking. Don’t get me wrong: There are a variety of reasons why mainframes i... (more)
