people complain about mobiles phones and how, according to them, they actually and ironically don’t connect people but isolate them. i was thinking that perhaps these people are right in their observations, but not in their conclusions.

seems kids these days pay more attention to their mobile phones in class than they do to their teachers (“damn mobiles”, i hear grumpy teachers say). but not only kids exhibit this lack of attention ability. the image of a person, or two, or five looking down to their mobile phone’s screen during a meeting is now common in any team meetings in the offices of companies all around the world. almost not surprisingly, as i have these thoughts right now while i prepare my breakfast and i look through the window to the street outside, i see these workers doing reparations in the street from which one is driving a carving/hammering machine and opening some holes in the pavement while the other two, which perhaps are there to supervise, are busy with their mobile phones.

now, instead of doing the conventional and demagogic judgemental assertion “mobiles are the problem”, what if the mobiles were simply channelizing to the outside world the more embarrassing fact that, over all these years before we had mobile phones, people had been distracted and not “working” as we had expected without anybody noticing. perhaps it’s just that we no longer pretend.

cause i don’t see companies being less efficient than they were before due to the distracting mobiles, i don’t think the works in the street outside my apartment would be executed quicker if those two guys weren’t on their mobiles. the world keeps turning at the same speed i think. it’s that we were not as busy as we though perhaps, and while before we were thinking on donuts and boobs while the boss speaks, now we check facebook or twitter (which also have donuts and boobs).

so perhaps it’s US who are distracted by nature, and the phones are the symptom more than the cause?

not sure what tory, itage and ths are, but they belong to the three of us

This week was really busy and hard. I could only doodle a bit, not really engage into a complex mathematical image. Yet I think it turned out quite cute. I used some variation of the famous “popcorn” formulas, although to be honest any random combination of trigonometric functions would have done equally well. I put them under iteration and then massage the different properties of the resulting orbits till I got something visually interesting and pleasant (some people have indicated that it looks Dalinian). You can see it moving in realtime here: https://www.shadertoy.com/view/Mdl3RH, and change some of the formulas if you fancy (I recommend starting with lines 6 and 7). See you next week!

it’s not often that the sun visits us here, but when it does, SUN Francisco gets really pretty. everywhere. but in particular i like it in the downtown area where the big buildings and life happens, the place in this “city” where i actually feel like using such word, and where at sun setting time the rays carom in complicated reflections and diffractions though the windows, corners and streets. it almost seems like the sky was trying to tickle the city before letting her go to sleep (for me a city, especially a pretty city, is always a “she”).

as this city transitions into a town in my way home, heading west, i am lucky enough to have to climb two of the seven hills. lucky, because at sunset time, seven hills mean seven different sunsets that you can enjoy. lucky, and happy to reach the top of each of my two hills, get to meet the sun there for some magnificent views and extra tickles before arriving home.

to me, complains of the type “but they tell us how we should live our lives” are legitimate only to a certain degree. cause, boy, it’s up to you to choose who deserves being listened to. as far as i’m concerned, nobody around me is telling me anything about how to live my life. i cannot hear them. furthermore, who’s “they” anyway?

My mathematical image of the week (number 3 in my one year challenge). A rework from an old piece from 5 years ago, plus lots of love and massaging for a whole long, long night. Planes, cylinders and cosinuses. Mission accomplished. Till next week!

You can see it moving and modify the code/formulas/image yourself here (you might want to change that first 1 in line 83 to a 0.0, then hit the black triangle below): https://www.shadertoy.com/view/lsf3zr

i don’t like computers, technology, tech conferences, games, films, entrepreneurship, installations, white PCs, linux, apps, websites, feeds, fanzines, comics, 8 bit music, meetups, hardware, resolutions, gigahertz, IPOs, markets, tablets, opportunities, startups, game conferences, film festivals, photography, directing, PROGRAMMING, forums, business. those words give me headache.

i do like making things that didn’t exist before, hopefully aweing people with them, and then in the spare time resting, sleeping, skiing, dancing, pianoing, staring at the wall, walking in the city, being naughty, being VERY naughty, exploring, taking long showers, doing stupid things, writing. did i say sleeping?

however, sometimes i need to be a nerd for work during a few hours a week. it’s professional.

why didn’t “anywhen” become a word?

my neighbors are fucking fast. fucking as a verb, not an adverb. they’re very robotic too.

i think it’s the ones right above me, but i cannot really tell cause they are very silent themselves, i only hear the rapid and mechanical hits of their bed in the wall. in fact, they are so perfectly periodic i think their fornication would make a good metronome for me to play piano. | crotchet, crotchet, crotchet, crotchet | crotchet, crotchet, crotchet, crotchet |

seems that someone from the hotel staff had a message for the hosts in floor number nine.

i’d say that while most things are indeed delicately interconnected, some are brutally interconnected

this is the only place on earth where wind hits you from north, south, east and west, all at the same time. which is physically impossible. yet, it happens. in particular, the cross streets of Post & Powell and Pine & Van Ness don’t follow Kirchhoff’s first law of current.

oh boy… i really, really love this place. but precisely because of that, like with the other places i love, i cannot but be critical with it. so here:

it seems people here “believe” in global warming. i know! like if we hadn’t collectively agreed on these things already, like, i don’t know, 400 years ago. renaissance anybody? or perhaps i’m getting it wrong, and we do “believe” in iphones too?

of course everything is and should be subject to doubt and critic, but please, if we go that road, then let’s be serious about it please.

So, seems i have publicly committed to creating one new and original real-time mathematical image a week, for a whole new year. Yeah, what a suicide exercise. But no fear, I’m sure it’s going to be fun. As with vomiting lines in this blog, hammering my piano or crawling to work, improvising this formulanimations will become one of those habits that don’t take much, yet are delicious.

Last week I improvised some clouds, so I thought of doing something less natural and more abstract this time: a cubescape. It actually reacts (dances) to the music, so it’d be a good idea to see it live here (you’ll need to do this in Google Chorme): https://www.shadertoy.com/view/Msl3Rr

i live in a perpetual and irreversible jet lag

i have a couple sitting next to me. they are in their 50s. i think they must have had a fight a few minutes ago, cause they’re obviously (still) angry at each other. they’ve been drinking, i can smell it from here. their dirty, ragged cloths tells me they are tramps, or homeless, or quite close to be. who knows what’s their story, what dragged them into this, into a slow decline into homelessness. when i see people in the edge like them two, it always makes me shudder, i simply can’t get used to it. i wonder if that’s why they fought. it surely must be difficult to go through it.

they boarded in the previous station, and sat next to me. in front of us there’s a lady. she’s in her 50s too. she’s wearing some elegant pants, jacket and a purse. she’s looking at them since the moment they came in and sat.

she’s examining them, and given the expression in her face, she’s clearly disproving everything she sees in them. she has even muttered a few words. as the train arrives to the next station, and the one after the next, and as we arrive to the third stop yet this woman hasn’t even blinked nor moved her intense sight away from them, i start to get really tense. i nail my eyes in her, and stare at her intensely till, after a minute, she realized and sees my eyes in fire. she looks to the window for a while, then looks in our direction again. but i’m still looking at her, so she picks her smartphone and starts doing something with it.

the couple sitting by me were busy enough with their anger, thoughts and problems as to have noticed the woman’s judgemental inspection they were undergoing. probably they wouldn’t have cared. as for the repulsive woman, the one in front of us, she’s probably not even read or understood my unspoken message. those people never do.

I love doodling. This is not anything new.

Doodling is not only fun, but convenient too. In these days of real-lifeness, lots of work and little time, short small doses of pleasure can be an alternative way to satisfy your addictions, dependencies and needs.

This morning I was testing some framework I developed for live coding, and soon the intended pure feature check exercise developed in a full mathemagical doodling session. This happened during breakfast. The sky was blue outside my window. But unless accompanied by a good gradient of sunrise/sunset colors, I don’t like clear blue skies that much, they are dry and emotionless, they lack interest and beauty (aren’t interest and beauty the same thing?). Seems my compulsive half hour of doodling tried to fix the sky outside my window, also compulsively. Clouds are beautiful. They have a shape, colors, shadows, volume, movement, they fly majestically above our problems and concerns, and they even cry.

As usual, a few lines of code implementing a primitive raymarcher into some noise density field is all you end up needing to create the illusion and bring clouds to your picture. You can see these clouds move, and play with them if you so wish, here: https://www.shadertoy.com/view/XslGRr

engineers are those with the almost supernatural ability to concentrate all their attention in a ridiculously tiny part of a problem and focus on it for days, months and years tirelessly. and still completely miss the context of the actual problem.

an sure you need them to get shit done. sure they will ask tons of money for it, and sure they very well deserve it! but they might need extremely close supervision and strict direction in order to not get lost. remember, focusing in details is their thing, not seeing and understanding the big picture.

yesterday i did part of my commute by cable car. why? just because. need more reasons? ok; because of SF. and because of A Quai. also, because of the weather, and the light, and the morning. because the cable car leaves from my block, because of the smell of wood and sound of the gears. lastly, because i wanted it so. in summary, “just because”.

La Dispute, second attempt

and this is as good as it will get to be for a while, i’m afraid – the next step requires months of training. will do, but time needs time

every time i get off my bike i do a ronde jambe en l’air, and pose my right foot smoothly in the floor, grateful like a ballerina. i don’t know why i do it, but i like doing it. perhaps it’s one of those things that i do to remind myself that, no matter what’s going on today, there was a not very distant yesterday that was warm and beautiful too.

why, why is it, that a skirt is never too short, and there’s no heels that are too high?

thoughts on sexyness and its mysteries

among the many things i’ve done today, these are the ones that come to my mind right before falling asleep:

* i enjoyed a gorgeous sunny summery day while cycling to the office
* met a stranger in the bart
* had a gift on my desk when i arrived to the office
* made my very first spontaneous (and decent) joke ever in english (i’m pretty proud of this)
* caught up on life issues with a good friend of mine
* had three steaks for dinner
* pixelated a full Nyan Cat animation by hand!
* plus many more little things

now, smile and Zzzzz

from the three factors in the formula

luck + work + time = success

one is unavoidable and one is uncontrollable, but the third one is a choice.

worth mentioning i’m not talking of success in the american meaning of the word

code is to data as energy is to mass

they’re not the same thing, but they are interchangeable

not like sex and chocolate

but seriously, algorithmic representation of things can be traded for bytes, as any mathemagician and demoscener knows by now

i’m sorry to announce to the world, that “fractals are not everywhere”.

there are just in some places. despite the clouds are not spheres, and the mountains are not cones indeed… well, flowers are not fractals, and neither are the reflections in a lake.

and i say this despite i’m one of the nerdiest people on fractals and complex dynamics you might possibly get to know

i knew i couldn’t be the only one in my discontent with regards to the use of euphemisms.

i’m at this very fancy and famous hotel in the downtown LA. fancy roof, fancy pool, fancy lobby, fancy people and fancy bathroom. and there, in the fancy bathroom, i find this very graphical icon in the so called bathroom tissue (or fucking simply toilet paper). aaaaaaand this discovery makes my day. i . love . it

why does everyone smile to me today? well, i don’t mean everyone of course, but i got five gratuitous smiles while in my morning and night walks in downtown to and from work.

i’ve nothing in my face today, i’ve checked, and my fancy edwardian/victorian beard is gone. nothing happened last night neither, and no special events occurred lately for the matter, so it cannot be cheerfullness irradiation of any sort. fly is closed, and i’m wearing my regular cloths.

why does everybody smile to me today!!!!

so, this is the other song i’ve been playing.

i tried recoding it today, but i think i need to learn what’s a good placement for the micro to best capture the piano, because it sounds really bad. all i can hear in the recording is the (repetitive) left hand part, and little from the right. maybe i should close the windows when playing in order to get less noise, that would help.

in fact, you can clearly hear a car passing by the opened window in the middle of the recording. yeah, playing piano with the windows open? am i crazy? i’m very shy for most things people are not, but i’m not shy about showing my intimate secrets. weird? meh, just me!

anyway, here’s the link – and you’ll notice that i’ve skipped the most interesting (and difficult!) part of the song:

La Valse d’Amelie

ahhh, this is an amazing beautiful morning. and it’s late, i’m sure there’s no neighbors around at this time…

i’ve been practicing this one song for a long time now, but i’ve done little progress with it. there’s a passage when things speed up, and my fingers, which had been traditionally been known as “fast fingers” and even “magic fingers”, are in this case too slow and clumsy to satisfy my own expectations. it’s not in my nature to give up, so i no fear loosing my battle. yet, this morning i’m taking a break and trying a new song.

first think is opening all the windows and let the sun lit the living room. then i give a listen to la dispute, which is slow and melancholic, and starts slow and without complications. yes, it’s the perfect candidate indeed. i’ll try this one today. so while the apartment breaths the wonderful warm air coming from the open windows, i go into youtube and carefully watch a guy play la dispute. i observe the chords (the right hand usually knows how to play already). hm, not many chords, and pretty regular. then i jump excited into my seat next to Teresa and start playing almost obsessively.

seems after 5 minutes i sort of got it right, and in 5 more minutes i have something that in my mind resembles the beginning of the song. not in my hears though, my fingers are still clumsy even with this simple song, which reminds me it was a good idea to do this while there’re no neighbors around. timing is not good, and the volume into the notes is not correct neither. but i’m happy to see that my pattern recognition, ear, spatial memory or whatever the heck one needs for hearing+seeing a song then play it, have evolved quite a lot. fingers will follow one day. perhaps. hopefully.

but for now, it’s time to water the plants, close the windows, and run to the train station.

(sorry for the crappy sound quality)

La Dispute

i spent another one hour today in my real-time procedural mathemagical experiment.

i won’t be able to afford more than that for at least two more weeks, so when i found this short opportunity for coding today i though i might add something quick and easy to develop. like some small lakes scattered around the terrain, which are common in alpine landscapes during spring when the snow melts.

lakes are all about reflections, which are usually expensive to make, so i gave a try to screen space reflections. i have no idea where or when i read about the technique anymore, or how i got inspired to code something in those lines, but i improvised a small loop with a few raymarching steps against the depth and color buffers, et voilà, i got some surprisingly acceptable results! extra points for being cheap. cheap like in “framerate doesn’t change at all” (i’m around 35 fps at HD right now). so, i didn’t complain, but go to bed with this feeling of “aha, that was easy…”, which is not the norm or even common when doing computer graphics.

when you are traveling in a plane and they serve you the meal (i know, lets pretend that thing is eatable), why, why the hell do they bring you the silverware in a plastic bag? it’s even sealed, for no good reason. unless the idea is to pretend this silverware had never been used before! but we all know these are not brand new forks, that these got cleaned from the last flight (and that’s fine by us, clean silverware is clean). the part that makes me angry is that they know that we know it anyway. so what’s this fucking game going on here? stop enveloping them in a plastic bag, for the environment’s sake!!! thanks in the name of the planet.

i’m listing together the things that crossed my mind today that otherwise wouldn’t be worth a post by themselves, in no particular order:

* “almudena”, which is a proper female name, has its accent in the e, but it would sounds even more beautiful if it was a dactyl instead – stressed on the u

* the lamp in my mathroom looks like a boobie

* it’s january, yet i’m wearing nothing more than a t-shirt

* i do lots of mistakes in my life. yep

* the forty fifth key in my piano is slightly out of tune

end of list
