We are entering an area of our galaxy densely populated by asteroids and other space rocks.

You might have noticed the recent increasing in reporting of space rocks that will pass very close to our planet. Well the reason of this is that the Sun travels at the incredible speed of 828,000 km/h dragging us with it every day in a new place, almost 20.000.000 km apart from yesterday. Check this.

Why you really need to change your view on space

The old heliocentric model makes us perceive space, stars, planets and other objects as they were revolving around one static star. Also this suggests the wrong idea of a static universe or at least as static as it gets to be observable during a human lifetime.

Cmdbuild 3.1 installation on RedHat or CentOs 7

I believe that some people might find this small script useful.

Anyway, watch out the variables, also keep in mind that not everything as been set as variable. There are no checks on existing things (except on postgres listening) and it will execute commands anyway, it should be idempotent though..

Postgresql scl enablepfffff. Persist already!

It might happen (usually to people who are sane in their mind) that you use the software collection just to get a newer version of Mariadb or Postgres or whatever is in there. So just to be clear: this is not the situation where you want to run two different version of the same package on the same system. That is booboo and if you found that in your workplace it means that the people preceding you didn’t exactly give a dam about having a safe environment and a pleasant workplace.

Tube amplifier explained

I found these two videos really awesome in explaining how a tube operational amplifier works.

Bowers & Wilkins DM22 fix cabinet, filters, grill clothing

Found these speakers for a handful of euros so i bought them with the idea of cannibalise them for the tweeters to use for a pair of tweeterless DM5. But turns out that while the DM5 run a TW20 tweeter, the DM22 run a TW26, so the transplant is not going to happen for incompatible donor. What is going to happen instead is that I will sand a bit the cabinets because over time discolored in some places and probably have been toasted by sun rays in other spots making them a three-color thing.

Geloso G3227-a vacuum tube amp, revive project

In the '80s a hospital in Den Helder, built in the '60, was renovated and one of the guys working at that renovation found, removed and took home this amplifier that i bought after almost 40 years. The amplifier was used for announcements on the microphone to be sent to all the speakers in the hospital.
