Moonwalking with Einstein
So I finished this one, and I can say it was a nicely put book about the subculture of memory athletes, together with some insights on the most used techniques by themselves to remember insane number of random numbers, or words, or poems.
Long time ago (around 2008) I read an oreilly book called Mind Hacks, which teached some techniques to 'overclock' one's memory, or recall, or mental arithmetic. I remembered the "1 is a bun, 2 is a shoe" placeholders, but here I learned about PAO, the major system and the Dominic System, to be able to remember random numbers (I now know my credit card by heart, after all those years).
I'm now working on my own PAO list (I'm using a mixture of Dominic System and arbitrary associations), and I hope to get to some decent proficency of memorization of numbers and tasks using the technique of loci.
A chapter on Savants, mentioning Brainman (highly recommended), and references to Tony Buzan and random folklore from the 90's make it a very enjoyable fast read.
Overall I liked the book quite a lot, it was fun to read, and I definitely got something from it. I'm afraid none of these techniques used by Memory Athlets will be very useful to retain the kind of information I usually need to remember like programming APIs, data from books (like memorization techniques, heh), or some data that needs to have more context than just a random number.
Anyway, I'm convinced already that the fact that converting things to vivid images and placing them in a memory palace greatly improves recalling.
Next stop, How to develop a perfect memory. And I think that will be enough for this streak of self-improvement.

Xamarin on linux
So the whole thing starts wanting to try Xamarin, for a meetup I'm going next Saturday.
The story goes in the following way:
The story goes in the following way:
- download and install VirtualBox
- get some Windows CD/iso. (Windows 7 in my case, to make it the least bloated)
- Install windows7 in a Virtualbox.
- Realize that you have no space left because Windows needs about 16Gb
- Remove some files from my hard drive until I have 25 free Gb. Not very happy to do that.
- Install windows7 in a Virtualbox with a 25Gb hd ".vdi" file.
- Try to store the vdi file in a usb drive so at least I have a quick backup to restore from.
- Realize I can't move 4Gb+ files to my usb drive because it's vfat (because windows compatibility)
- /shrug and think "it will be fine" no backup
- Get visual studio comunity edition.
- Try to install it....
- wait
- wait
- wait
- Install xamarin & android sdk from the installer.
- Fuck, it needs 8Gb+, and I don't have them available.
- Try to increase the hdd volume. The instructions are scary. And for windows hosts.
- cold sweat
- Share a folder with the guest OS.
- Can't install software there.
- Flip table
- Realize I don't want to have anything to do with a system that requires 30Gb+ of bloat to write a single hello world. That I cannot ever move from my hd because it doesn't survive in a vfat hd (that I have in this format ONLY to make it compatible with windows)
- Remove the whole crap.
- Go learn something useful and fun. It's not that there're no candidates (Rust, Clojure, Reverse Engineering, MachineLearning....)

Birds of a feather lisp together
Now that I have some time in my hands (and I already mis Lisp), I'm watching several old Lisp talks, and stumbled upon This event.
On December 3 and 4 of 2004, the Computer Science Department at Indiana University hosted this conference on the occasion of Dan's sixtieth birthday.
Guy Steele's talk is great, as always. Nothing surprising there. Talking about Dan's ideas and Dan itself (and giving a feeling about Dan being isomorphic to what Gilad Bracha says about Luca Cardelli here).
Gerald J Sussman's talk is also very nice, again, as usual.
And all talks I saw have that lispy emotion that we love.
But something that stroke me the most (that after reading 'The information' I realize more) was when Guy Steele talks about the time he read a draft of GEB. It's also a warm fuzzy feeling. Reading GEB leaves some trace in the reader forever. You never read a book the same way, or look at reality in the same way. Same happens with SICP (in process analysis).
Then I realized that in the picture of the event, there are the 3 of them. gls, gjs, and Douglas Hofstadter. Because obviously, they are "friends". And the realization that the authors of my 2 favourite books ever hang around sometimes.
I also remember some Alan Kay talk where he says something like: "a few hours ago I found Guy Steele in a corridor in this event and we talked about blablabla.....". 100% natural :)
Then, while researching a bit for this post, I browsed wikipedia for Hofstadter. And another "proof" that "among certain level of smartness, there's just 1 degree of separation between any two people".
[...]he organized a larger symposium entitled "Spiritual Robots" at Stanford University, in which he moderated a panel consisting of Ray Kurzweil, Hans Moravec, Kevin Kelly, Ralph Merkle, Bill Joy, Frank Drake, John Holland and John Koza.
