p≡p-mail-tool: easy privacy for email with existing Mail User Agents (p≡p is working with Gnus!) — 2023-08-07 03:05
Updated: 2024-01-11 12:15

During the last month and a half I have unfortunately mostly disappeared from GNU, having been busy and focused writing p≡p-mail-tool (https://codeberg.org/pEp/pEp-mail-tool), a new work project I have let overflow into my personal time as a beautiful little hack in which I believe. p≡p-mail-tool is of course free software. Motivation Freedom of speech and privacy are more and more threatened by governments and hostile corporations working against the public interest. In this season of death of liberty the minimum we can do to respond is making surveillance more difficult, by providing the general public with easy tools to use for [...] Read more

Announcing make-gallery, a simple web image gallery generator — 2022-11-21 01:33
Updated: 2022-11-21 23:53

I wrote a script generating an image gallery suitable to be included in web pages. Since it can be generally useful I cleaned it up and published it, of course as free software (https://www.gnu.org/philosophy/free-sw.html); you are welcome to download a copy of ‘make-gallery’ from <https://git.ageinghacker.net/make-gallery>. The software is released under the GNU General Public Licence (https://www.gnu.org/licenses/gpl-3.0.html) version 3 or later; the generated code is in the public domain. I hate the web I have never made a mystery of my personal dislike for the web with its gratuitous ever-growing complexity, inefficiency, lack of expressivity, hostility to the developer and to [...] Read more

SMTP, OrangeWebsite and using your own computing resources — 2022-10-24 00:35
Updated: 2024-01-04 19:55

I have had a personal server with the domain ‘ageinghacker.net’ since 2010. At the beginning I was sharing hosting costs with two or three other people, each of us running a virtual machine inside a Virtual Private Server. By 2016 my requirements had grown, I wanted stability and so decided to rent a VPS by myself. Around that time I had also decided to run a Tor exit node for the benefit of the global community, and more in general wanted my server to be in a country that allowed some freedom of speech; since I did not, then like [...] Read more

Global variable initialisation in C++ — 2021-11-18 22:00
Updated: 2022-11-26 18:37

Today Volker Birk (https://fdik.org/) and I were speaking over lunch about object initialisation in C++ and about how weakly defined a program entry point is, because of objects with static storage duration. Volker wrote a short program whose output changes after reversing the order of two variable definitions, both out of a ‘main’ function whose entire body was ‘return 0;’. He discussed it in German (https://blog.fdik.org/2021-11/s1637238415), on his blog (https://blog.fdik.org). I was more annoyed by the fact that initialisation order is not guaranteed to respect functional dependency across compilation units. Here is my test case, where GCC and the GNU [...] Read more
