Energy and sleep

Some days I have the feeling that sleeping is essential to keep productive.

Other days the fun of keeping working on something takes all the need for sleep away.

It’s not only how much we sleep that matters, it seems, but also what is keeping us from sleeping.

Welcome to Hell

“Any given Saturday” (Um sábado qualquer) is a Brazilian comic from Carlos Ruas about gods – lots of them, from the Christian God and his son to the Nordic, Egyptian and the African and traditional Brazilian gods – they all show up now and then. This one strip is about hell…


the conversation goes like this:

– Welcome to hell! Football starts at 14h, the barbecue starts at 16h, the strip show starts at 17h…

– You are not going to torture my soul for all eternity?

– Of course not, little fool. God made that up to frighten you.

– You are here because you didn’t follow the words of god, right?

– Right.

– I’m also here because I didn’t follow the words of god! Welcome to Paradise!

I’m saying this for years. Who want to go to heaven? Everyone praying and behaving very up-tight… it sound like hell to me.

The Dream work

One of the things that keeps surprising me is the lack of dreams.

I understand quite well those who don’t do anything or that don’t manage to finish much – I’m planing on buying one of those T-Shirts that say “I put the Pro in procrastinator” – After I start writing this story I did replace the aromatic candle I like to have in my table, and then looked for the T-Shirt, but not happy to find one, I did find one, two, three… hell, a full category of them

But the lack of dreams surprises me. Asking someone “What would you like to do?” or “What would you do if money was not a problem?” and getting “I don’t know.” as an answer confuses the hell out of me.

Dear authors

Dear authors,

I love to read. And the space in my shelves is more than gone.

I know that a lot of you are already being published in digital formats, but If that is limited to the big publishers who use DRM, don’t count me as a client.

But in general I’m more than willing to pay for your work. But I only in an open format, DRM-free – epub is my personal preference.

Now, personally I get most of my ebooks from smash words, but if I really want to get your book, I’ll find your site and where to get the book from.


We just created a new word at coffee today:

Artscribing – artscribing is the art of creating meaning for and/or describing pieces of art, specially for abstract modern pieces that don’t have any apparent visual resemblance with pre-existing things.

In a less formal way, what it really means is taking some meaning or description for a piece of art out of one’s ass.


Streaming Average

Just because I keep forgetting it and having to find out all the math manually again!

The two main reasons to use something like this is if your total is too big and you don’t care about standard deviations – I’m pretty sure we can come up with a streaming formula for the standard deviation as well.

Also, if you @rows is some type of stream in which you have a way to get the next value and you want to know the average so far at any given point, this is the way to do it.

Beal’s Conjuncture

One of this days I come across the Bael’s conjuncture and the Bael’s Prize.

The conjecture is a generalization of Fermat’s Last Theorem, that states:


A^x + B^y = C^z,

where A,B,C,x,y and z are positive integers with x,y,z > 2 , then A,B and C have a common prime factor.

This is still a conjecture, meaning that it was not proved or disproved. And that got me thinking, because it doesn’t seemed that hard of a problem. It didn’t take long for that to turn into a dialog between the (ex-)Math student me and the programmer me.

The programmer said that all it takes is a script to test a decent chunk of all the possible combinations until you find a case that doesn’t satisfy the needed requisites, while the math student argued that that would only work if the conjecture was not true, because you can’t brute force a math prove for bbR.

Which is true. The only way to truly prove that the conjecture is valid (and making it a theorem) is going through one of the several methodologies mathematics define for this.

This is, maybe, something for a day I feel really bored. And most likely the programmer will win and try to find a counter-example first.

My blogs

Today I was once again upgrading all the software I use for my blogs. Lately I spend a lot more time upgrading the software than writing posts.

It doesn’t take too much time as I automated most of the process, except that I still need to download and push to my own git repositories the latest versions of the plugins and themes I use – as I needed to make small adjusts in some of them.

That, however, is the less important part of this. The important part is that since August this is the second post I publish, being that the first one was a couple of weeks ago – this comic. And that is across all the nine of my blogs.
