The black hole…
Today I took a long time, together with folks from the eXist-DB Community (thanks Luca Guariento and line0 for the brainstorming), to figure out why a function was receiving a node sequence instead of a single node. The question was why using this code was not working: And fn:lower-case was complaining for receiving a sequence […]
Today I stumped on how to create a XML document, storing it in a XQuery variable, that is composed from both a processing instruction and an XML body. While this might seem easy at first, creating the document as once: The truth is that this does not work. Nevertheless, there is a set of ways […]
I’ve been using eXist-DB for some time for the project of the Dicionário da Academia de Ciências de Lisboa, that is being revived from the PDF into TEI, so that a new digital version can be soon released. Recently I needed to update the server where eXist-DB was running, and decided to use a dockerized […]
I have been using the Text Encoding Initiative Guidelines to encode dictionaries. I used it originally in Dicionário Aberto, and more recently in a work with the Portuguese Dictionary of the Lisbon Science Academy. In the last week I started teaching a course on Digital Lexicography (do not ask what that is, it is just […]
I’ve been working on some notes for my students on Neural Networks. I am using Pandoc to write the text, and convert it back to LaTeX for PDF generation, and to HTML, for making the documents available online. In a future post I might talk about Pandoc, but for now, I want to share something […]
(cross posted from blogs.perl.org) I am planning on a new project, and a friend suggested me to look to Arango, as an alternative do Mongo, specially because it includes a graphs query language integrated. As I am not really used to Mongo at all, decided to give it a try. Unfortunately I did not find […]
I am not sure about other countries, but in Portugal there are some mobile phones (usually not smartphones) which are catalogued as for elder people. As you can see above, they have big buttons, with large numbers. But things stop there. If you try to use any of them, you will notice that the text […]
First of all, please do not read this post as a complain. Just as an analysis. I am a Linux user for decades. I remember using Linux in my first year of University, somewhere about 1996. I never stopped using Linux, in the server, but during some years, somewhere between 2002 and 2017 I was […]
The traditional way to have a C# MonoGame Project compile both under Linux and Windows is to use a tool named Protobuild. With the last version (3.6), the MonoGame OpenGL template for a cross platform game includes references to the libraries in the three main formats: DLL for windows, DyLib for mac, and so for […]
Euclidea is a very interesting game. Something new, a different game, educational, fun, difficult, challenging. A great game. If you like geometry, if you loved how to build geometric constructions on paper, but always made them blur, you will love this game.
