A few days ago I was talking with a very big, top player, database software company. Sure you can guess their name, but allow me to not providing any clue. We were talking about licenses of their flagship DB product for a project we are driving, and I was very disappointed for the behaviour of the account manager I was talking to. Basically the dialogue was something like this: - I need the most

Recently some news in the photography market makes me think that digital camera manufacturers are focused on other things than megapixel count. And that's good news. In my humble opinion, to fight for more and more pixels in a compact or entry-level DSLR camera, while not improving the optics neither providing significant improvements to the features of the camera, apports very little value to

It seems like 2009 will be a hard year, a really funny year. We're working harder than ever, both because of new customers demanding services from us and existing ones wanting more and more services (good!), but also because of new services we want to launch to enter in new market segments.In these days of really hard work, uncertainty and crisis (probably more fear and panic than real problems),

Nowadays there's a lot of buzz about "green". It's fashionable, it's "chic". Every equipment manufacturer claims to be the most power efficient in its area, and green is used both as a way to say "we are the best because we're the ones to take more out of the hardware" and as a way to improve the corporate social responsibility of the company. But, what's really important about green? Will the

Imagine you drive the traffic of an airport. This airport has 5 landing/runway strips that can be used simultaneously. To avoid turbulences and problems, a clearance time of 3 minutes must be wait after an airplane take off and before the next one can take off. If 2 minutes are needed for a plane to take off, it means that a maximum of 1 plane every 5 minutes can take off for a given strip. It

I often like to read the biography of those people who had improved our world leveraging their knowledge to science, and making a fair use of it. There's a lot to learn from great people like Marie Curie, Darwin, Newton and many others. I’m convinced that everything we learn can be applied to our life to make it better. Michael Faraday was one of these great men, in my opinion. Reading the

Title: Confesiones personales de un publicitarioAuthor: Lluis Bassat Type: self-biographyThis is the last book I've been reading and I must say it's very good. It's a kind of selfbiography from Lluis Bassat, the famous publicist, where he summarizes some situations from his life and thinks about it, showing his conclusions. The book, written in a very plain and easy to read language, is divided

My colleague Miquel sent me a very nice and useful document for Unix guys: the unix toolbox. You can download it in PDF! It contains a lot of commands reference for gathering system information, encrypting files, managing the file system, certificates, version control systems, databases and lots of other stuff.Maybe nothing new for "sysadmin masters", but a very nice reference document for any

I've just seen what Johnny Chung Lee is capable to do with a $40 Nintendo Wii remote controller. Listen to this Ted talk and see it yourself. I think that this is just the beginning of a great thing. Not only because of the possible wide spread of its uses because its low cost, as Johhny says in his talk, but because it maybe the start of a brand new set of HIDs. I'm not talking just about Wii.

Few days ago Jose Luis and I were talking with a customer about how to scale some parts of his data center and applications. This customer is currently using some of our solutions to scale out they database systems. The question that this customer was asking to us was if he should scale out or scale up. Scaling up is more limited that sacling out, but a fully transparent (to applications), easy

Recently I had to setup several Apache web servers with an in-RAM cache for frequently accessed content with the help of Apache's mem_cache module. All the servers where front-end servers to application servers that sits behind.Although in some cases the content expiration time was set as low as 30 seconds, it worked great because it reduced request concurrency for the most costly requests,
