Heart Rate and Calories Burnt - How Do They Relate?

You’ve heard me chat about calorie counting, and you’ve heard that I use a heart rate monitor to figure out how many calories I burn on my workouts. You’ve heard my surprise at finding out that “starvation mode” is measurable in the heart rate – reducing caloric output during the day, forcing lower calorie consumption and the usual “plateau” effect in many starvation diets. But why is there such a strong correlation between the heart rate and the calories consumed? Continue reading

Rockbox on the SanDisk Sansa Clip v1

I’ve been fascinated by the RockBox project for a while now. It is an alternative firmware (i.e. OS lite) for music players with a bunch of extra features. It is being ported to a range of different devices and it is becoming the Linux of sorts of MP3 players. (Soon to be replaced by actual Linux, one presumes…) The first device for which I had a RockBox port was an old iPod, the ones we would call “classic” these days. Continue reading

R.I.P. Kindle

The disturbing trend of electronic gadgets dying earlier in their life span continues. My Kindle gave up yesterday. I turned it on, and the e-ink display was broken, showing me weird streaks on the top right portion. It looks like blunt force, but the reader was not exposed to any force. Well, I was kinda happy with my Kindle – loving the wireless connectivity, long battery life, and clarity of the display. Continue reading

Open Source and Interfaces

One of the things that complicates the development of software in the open source world is the enormous variety of different interfaces you have to deal with. This is eminently an architectural problem: interfaces need to be defined ahead of coding, and if you just start developing your own project, you have no need for uniformity across projects. Initially, of course, there is no standard and hence no interface. Later, separate projects come up and they make a point of having different interfaces to better spread and create incompatible ecosystems. Continue reading

Developing for Maemo - Fremantle VirtualBox Image

So I’ve been playing around with the Fremantle VirtualBox image that Maemo.org provides on their web site. The idea is great: you get the image, run it in a virtualization environment, and you don’t have to set up anything. Great idea, poor implementation. First of all, the image doesn’t come pre-loaded with instructions. I would have expected a big icon to show on the desktop after launch, telling me what to do next. Continue reading

The Suicide of the Kindle

Who remembers the time when Amazon deleted a bunch of books from Kindles? It was the dark ages of e-ink, Amazon was the undisputed master of ebooks, its marketplace was teeming with “publishers” that sold books in the public domain. One of those publishers offered a book whose copyrights had not expired. Understandable, given the absurd length of copyright extensions. In any case, what Amazon did next was completely horrifying to any book lover. Continue reading

Healthy Yummy Breakfast Recipe

I am realizing now that I’ve been concocting this recipe for years, improving the ingredients over time, and I finally have something I absurdly like and that is actually pretty good for me – and I have never shared. Here’s the deal – it’s so good that I sometimes fancy it up and serve it as a dessert for dinner guests (hint at the end). It all starts with what I like for breakfast: something crunchy, sweet, plentiful, but not weighing down; something with good balance of nutrients, with lots of proteins, healthy carbohydrates, fiber, and a good amount of water; and of course something that can be made quickly and without fuss. Continue reading

NoSQL - No: NuSQL

There is this whole motion afloat, trying to declare SQL bankrupt and do without. Instead of SQL, one hears, there are going to be much better databases in the future. Dozens of projects are floating around, each with a different notion of what “better storage” mean, all aiming at being better data stores for the Internet. Now, it is clear that SQL databases have their supreme annoyances, and the need for reform is clear. Continue reading
