For the purpose of writing this article I’m going to use the following definition of “operating system”. There are other definitions and I’m not claiming this is the right one. An operating system is a unit of software that you can install in a computer and will let you use the computer, thought a set of utilities or program in one way or another.

Recently my friend Juanjo pointed out how much activity my blog has been having recently. Thinking about it, he is right and there are two reasons why this may be the case:
- I’m more inspired than usual. I’m not sure if this is the case, and even if it is, it’s not helpful for me to communicate it unless I’ve found a way to find inspiration easily.
- I’m writing in parallel. Now this is something to talk about, because it is a technique that can be applied by everyone and I recommend to any blogger.
Squeak is by far the best and most complex Smalltalk implementation out there. It may not play well with other operating systems because it is an operating system by itself. It is also one of the most impressive development environments I ever seen. OK, the most impressive.
Or maybe there’s a message beyond my understanding skills.
I have just made a new release of Score Reading Trainer, 0.1.4. This release has a very important bug fix, thanks to Julian Kniephoff. The fix allows to use notes below the first line of the staff without getting the extra lines mixed and eventually crashing. It was also upgraded to compile correctly and easily to a current KDE, version 3.
After watching the OpenID community grow for years, I finally joined them. I’ve liked the idea from the first day I’ve read about it; aren’t we all tired, after all, of having to remember hundreds of usernames, passwords (sometimes with conflicting constraints: a password must have numbers, a password can’t have numbers)?
From OpenID’s web site:
OpenID means the elimination of multiple user names and passwords and a smoother, more secure, online experience. For businesses, this means a lower cost of password or account management, the opportunity for easier and higher numbers of new user registrations and the elimination of missed transactions because of user frustration with lost and forgotten passwords. OpenID allows for innovation in the authentication space beyond just using a password to “unlock” your OpenID identity, but the ability to strongly protect your OpenID and have that benefit move with you everywhere you go online.
For me, joining the revolution was very easy. First I open an account on MyOpenID, then I installed the OpenID Delegate WordPress Plugin in my wordpress blog so my OpenID address is, actually, pupeno.com. So even thought I’m using a third party service, if they disappear I just pick another one (or become my own OpenID provider) and go on using the same address, pupeno.com. Isn’t it great? There are many other OpenID providers and many sites already supporting OpenID.
SCons is a program designed to replace make and autotools. SCons being a new tool is built with all the knowledge of what problem really this kind of tool should be solving, while make and autotools were built while discovering the real problem. It is natural to expect SCons to have a better design that covers the big picture. Continue reading “Another simplistic solution, with SCons”
