uns dias depois, cá comecei a olhar para o bada numa perspectiva de utilizador avançado. o objectivo não passou de ver simplesmente se seria muito complicado desenvolver qualquer tipo de programa para a plataforma.

inverse perspective mapping
one of this year’s projects, and also the subject of my mini-research scholarship, was automating the process of obtaining an inverse perspective map (ipm) for an autonomous driving robot.
autonomous driving robots frequently use cameras for object and road detection. after detecting such elements in an image it must be able to locate them in the real world, or else the image serves no purpose. that’s the ipm: a means of associating points in an image to points in the car coordinate system. to do obtain it, one only has to understand the transformations that occur when points are projected in an image and undo all those steps, for each point of the image, thus obtaining the real coordinates of each pixel.
uma nova onda
bem, com este post mudo o tema do site. agora estou a usar o twentyten, que veio com a última actualização do wordpress. o motivo para isto é o facto de estar farto do visual antigo, mas não estar com cérebro direito para inventar um novo. de qualquer das formas, senti-me na obrigação de lhe dar um toque pessoal por onde o criador sugere, e foi então que peguei no telemóvel e dei um requinte à ideia matinal de tirar uma foto a um molho de t-shirts. peguei no gimp, posterize seguido de cartoonize e o resultado até que me agradou sem grande esforço.
i tried, i trully did!
yesterday i installed gnome after maybe a year of using dwm. it might sound strange, but i took some time to configure some stuff and after i thought i was done more stuff had to be done. as soon as i opened firefox i felt that something was wrong, i think it was the fact that my effective area of screen went from a relation of 16:10 to 16:9. i really noticed the difference and of course i could automatically hide bars, but that’s just stupid. also i cannot effectively manage my open windows and programs. not to mention the loads of processes running that i don’t even know what they are for and what i can do with them. plus, and though i love my (still almost as) new mouse, i prefer not to drift my hands from the keyboard as much as gnome makes me.
i’m sorry everyone, but dwm is not easy nor difficult: it’s simple. and so is arch.
why i still need the mouse
i was checking the old release pages from mozilla firefox, to check out when i began using firefox, but it looks like the guys at mozilla aren’t too much worried about history and having the old builds in the ftp. anyways, it’s not that important. i remember that i have used firefox before i even switched to linux, and it was around version 0.9, somewhere in 2004. i remember at that time it was a fast browser, far from bloated, and i already had that feeling that microsoft didn’t suit me that well. i used it as my primary option until 2-point-something, but then version 3 disappointed me somehow, or opera just attracted me better. i’m writing this post from opera 10 rc2, but i have been using firefox again since 3.5. and will be.

o melhor browser web do mundo chegou ao meu computador e chama-se vimpression! é só editar/acrescentar um par de linhas e faz (praticamente) tudo o que eu quero. grande leon winter!
the world’s bug inventory…
… grows every day. yesterday i was trying to import a formula anywhere from (la)tex to inkscape, so i could render it to any size i wanted. in the (failed) process i encountered several applications that didn’t work correctly or simply just didn’t do the trick as i expected. also when browsing some of the application’s websites i had a “page not found” answer. yesterday seemed like everything in the world that wouldn’t work correctly dropped at my browser step.

… after having pacman -Rncsed awk without a second thought last night. -R remove, -n configs also, -c dependencies too, -s recursively: initscripts went along. i noticed the problem in time and pacman -Syed initscripts again… being distracted with something else, i forgot the problem and, this morning, i had no login…
