There’s this funny thing about pouring two bags of M&Ms into one candy dish. The number of M&Ms is exactly the same as when you started, but now they’re all in one location. You have, in theory, saved yourself from having to wash a second candy dish, but the same number of people can enjoy the same number of M&Ms, you’ll run out of M&Ms at about the same time, and if you have junior high kids in the crowd, the green M&Ms will disappear at approximately the same rate. The big difference is that fewer people will fit around one candy dish than two, unless you take extraordinary steps to make that one candy dish more accessible. If the one candy dish is specifically designed to hold one or one and a half bags of M&Ms, well then you’re going to need a place to store the excess. The debate about whether data center consolidation is a good thing or not is pretty much irr... (more)

Android and SSL: What Doesn't Work

Not so long ago I wrote a blog entry about SSL on Android in regards to some certificates, and mentioned that I would be following up as the work progressed. I have worked through the options and implemented a working solution that I’ll eventually blog about, but this entry is to discuss what doesn’t work, or is a sub-standard solution, what I settled on, and why. It’s light on implementation details, but does offer enough information that interested developers can research a similar solution. The options I discovered or considered are: Forcing the user to import the requisite ce... (more)

Bare Metal Blog: FPGAs: Reaping the Benefits

All the goodness FPGAs bring hardware in general, and ADO hardware in particular. In two previous installments, I talked at a high level about the uses of FPGAs, risk mitigation, and the potential benefits. Today I’d like to delve into the benefits that the industry in general, and F5 in particular, gain from using FPGAs, and why it matters to IT. If you’re a regular reader, you know that I try not to be a chorus line for F5 solutions, but don’t shy away from talking about them when it fits the topic. That will continue with this post. While I will use F5 for the specifics, the ... (more)

The Future of Programming?

“We have achieved peace for our time” The Honorable Neville Chamberlain It is often the case that when you look at things a certain way, they become filtered over time, and you see what you expected to see. This happens to everyone, and while a wonderful adaptation to help handle all of the various inputs in our lives, has caused just about everyone to jump to conclusions because they think they know what they see. Neville Chamberlain did that. He (and his advisors) was certain that Hitler would keep the peace after he was given what the German people wanted. He saw Hitler as the... (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)
