How to increase serotonin in the human brain without drugs (Study) (via senmes)

In short:

* You have to self-induce changes in mood
* You have to catch some sun
* You have to assume tryptophan through diet (some advices in a future post)
* You have to go to the gym

“The study by Perreau-Linck and colleagues36 is the first to report that self-induced changes in mood can influence serotonin synthesis. […] Exposure to bright light is a second possible approach to increasing serotonin without drugs. […] Several lines of research suggest that exercise increases brain serotonin function in the human brain. […] The fourth factor that could play a role in raising brain serotonin is diet. According to some evi … Read More

The Good, the Bad and the Ugly (via Chemoton § Vitorino Ramos’ research notebook)


The Good, the Bad and the Ugly Fig. – Christ having some problems on passing the right message. Comic strip from Zach Weiner (Saturday Morning Breakfast Cereal blog – ). Social psychologists, sociologists, and economists have all proposed theories of norm emergence. In general, they views norm emergence as depending on three factors: (i) actors’ preferences regarding their own behaviour (inclinations); (ii) actors’ preferences regarding the behaviour of others … Read More

New software for designing autonomous artificial intelligence (via Machines Like Us)

Today, TinMan Systems, announced immediate availability of the TinMan AI Builder™ and Integrated Development Environment, enabling companies to rapidly design and deploy autonomous artificial intelligence in their host applications and systems.

TinMan AI Builder was developed as a result of the firm belief that increasingly human-like behavior is now possible through neural network based AI systems, but that those systems are very difficult and costly to develop and integrate.

Meditation training changes brain structure (via Machines Like Us)

Participating in an 8-week mindfulness meditation program appears to make measurable changes in brain regions associated with memory, sense of self, empathy and stress.

In a study that will appear in the January 30 issue of Psychiatry Research: Neuroimaging, a team led by Massachusetts General Hospital (MGH) researchers report the results of their study, the first to document meditation-produced changes over time in the brain’s grey matter.

How to remotely use your workstation with ssh and vnc

I assume that you use a Unix-like operative system, but this apply to any OS.

Let’s say about a problem: you are in your office, you are waiting for some kind of simulation to end. Everything seems to go well, so you go home, quite confident that the next morning you’ll have some results to analyze.

Unfortunately, it’s unlikely to happen. Ten seconds after your departure, the program ends for a low-frequency bug that you missed.

Luckily, we have a solution for the future. Instead of losing a long night (or even a weekend) of program executions, you can check your office workstation when you are at home, in your warm bed, or everywhere you like to be (with an internet connection, ça va sans dire).

What do you need in your workstation?

You need to install (or ask the sysadmin to install):

  1. the ssh server
  2. a vnc server: x11vnc

Remember to ask the sysadmin:

  1. the public IP of your workstation
  2. the range of unused open ports, if the workstation is behind a router

What do you have to do from home?

Ok, now it’s very simple. You’ll only need to install a vncviewer, but you’ll probably already have one. Let’s say that your workstation username is goofy, the public IP is, and the free open port on the workstation is the 5900. Now we need another port, this time a local one (of your home computer), to create the http tunnel. I suggest the port 5901:

ssh -p 42 -L 5901:localhost:5900 goofy@

You’ll have to insert your workstation password, and then you can explore with the shell your remote operative system. If you want to use it graphically, only execute the command:


Wait for 5-6 seconds, then open another shell without closing the current one, and type the following:

vncviewer localhost::5901

Et voilà! You have to move your mouse on the new black window, and then you’ll see the remote display to appear.
