Scanning heaps of 8mm movies
After my father passed away, I brought home most of the personal items he had, both at home and at his office. Among many, many (many, many, many) other things, I brought two of his personal treasures: His photo collection and a box with the 8mm movies he shot approximately between 1956 and 1989, when he was forced into modernity and got a portable videocassette recorder. I have talked with several friends, as I really want to get it all in a digital format, and while I’ve been making slow but steady advances scanning the photo reels, I was particularly...

Language, gender and videogames, using corpora to analyse the representation of gender in fantasy videogames
It has often been stated that the videogaming environment is filled with machismo, and there are many observations to that end: numerous studies have been published that back this assertion, based on the size comparison of the male and female gaming communities, on the graphic representations of male and female characters, on the interactions between male and female players in online gaming communities, and a long etcetera; the author quotes studies such as “Gender differences in video game characters’ roles, appearances, and attire as portrayed in video game magazines” by Miller and Summers [1] and “A content analysis of female...

Twenty years
Twenty years… A seemingly big, very round number, at least for me. I can recall several very well-known songs mentioning this timespan: «It was twenty years ago today Sgt. Pepper taught the band to play», sang four youth idols in 1967 for whom said timespan was not-quite-but-almost their full lifes so far. «Si las cosas que uno quiere se pudieran alcanzar, tú me quisieras lo mismo que veinte años atrás» (if what one wants could be achieved, you would love me the same as twenty years ago), says a heartbroken song by María Teresa Vera where she is resigned not...

Four days to fix a simple configuration bug
Phew! Today, after four days of combing through code I am unfamiliar with, I was finally able to change my expression. I’m finally at the part of my PhD work where I am tasked with implementing the protocol I claim improves from the current situation. I wrote a script to deploy the infrastructure I need for the experiment, and was not expecting any issues — I am not (yet) familiar with the Go language (in which the Hockeypuck key server is developed), but I have managed to install it several times, and it holds no terrible surprises anymore for me....

Now that we are talking about kernel building... What about firebuild?
After my last post, Bálint (who prompted it with his last post) suggested I should do a hybrid test of his tests and my extremes. He suggested I should build the Linux kernel using my Raspberry Pi 4 (8GB model), but using the Firebuild build accelerator. Before going any further: I must make clear that while Firebuild is freely redistributable, it is not made available under a free license. It is free for personal use or commercial trial, but otherwise requires licensing. Bálint managed to build a Linux kernel in just over 8 seconds. So, how did my test go?...

Impact of parallelism and processor architecture while building a kernel
Given that Bálint just braggedblogged about how efficiently he can build a Linux kernel (less than 8 seconds, wow! Well, yes, until you read it is the result of aggressive caching and is achieved only for a second run), and that a question just popped up today on the Debian ARM mailing list, «is an ARM computer a good choice? Which one?», I decided to share my results of an experiment I did several months ago, to graphically show to my students the effects of parallelism, the artifacts of hyperthreading, the effects of different architecture sets, and even illustrate about...

Jerusalem online critical cartography for the digital age
While cartography studies the making and using of maps, this book focuses on a specific case study of critical cartography, that is, when power relations and differing understandings of reality and politics change or shape the making of maps for a given location or community. The case of study looked at here is one of the world’s most contested and historical cities: Jerusalem. The author presents the power struggle in Jerusalem, taking a clear stand as a sympathizer of the Palestinian side–a view that shapes the whole book. She starts by explaining how cartography has been used as a means...

We are GREAT at handling multimedia!
I have mentioned several times in this blog, as well as by other communication means, that I am very happy with the laptop I bought (used) about a year and a half ago: an ARM-based Lenovo Yoga C630. Yes, I knew from the very beginning that using this laptop would pose a challenge to me in many ways, as full hardware support for ARM laptops are nowhere as easy as for plain boring x86 systems. But the advantages far outweigh the inconvenience (i.e. the hoops I had to jump through to handle video-out when I started teaching presentially, which are...

miniDebConf Tamil Nadu 2023
Greetings from Viluppuram, Tamil Nadu, South India! As a preparation and warm-up for DebConf in September, the Debian people in India have organized a miniDebConf. Well, I don’t want to be unfair to them — They have been regularly organizing miniDebConfs for over a decade, and while most of the attendees are students local to this state in South India (the very ``tip’’ of the country; Tamil Nadu is the Eastern side, and Kerala, where Kochi is and DebConf will be held, is the Western side), I have talked with attendees from very different regions of this country. This miniDebConf...

Back to Understanding Computers and Cognition
As many of you know, I work at UNAM, Mexico’s largest university. My work is split in two parts: My “full-time” job is to be the systems and network administrator at the Economics Research Institute, and I do some hours of teaching at the Engineering Faculty. At the Institute, my role is academic — but although I have tried to frame my works in a way amenable to analysis grounded on the Social Sciences (Construcción Colaborativa del Conocimiento, Hecho con Creative Commons, Mecanismos de privacidad y anonimato), so far, I have not taken part of academic collaboration with my coworkers...
