Prezados leitores, Sempre que preciso instalar uma nova instância do GeoNode, sigo os procedimentos que já compartilhei aqui no blog: – Instalação do GeoNode 5 no Ubuntu 24.04 – Instalação do Certificado SSL no GeoNode O passo a passo ajuda bastante, mas, a cada instalação, lá estava eu novamente:…

We're nearing the end soon, I promise. Here's one that I see all the time: ... } else { var_t0_5 = temp_a0_3 - 0x140; var_a2_5 = 0xA0 - temp_a3_5; goto block_45; } } else { var_t0_5 = 0xA0 - temp_a0_3; var_a2_5 =…

Linus Torvalds released the 7.3 kernel, at the end of the usual nine-week development cycle, on October 18. This cycle, abundantly fueled by LLM-assisted contributions, broke just about every record imaginable. As usual, we have compiled some statistics showing how this release, which is expected…

Rust has several ad-hoc mechanisms to allow user code to influence how the standard library executes. For example, custom panic handlers and custom allocators both involve registering functions that core standard library code needs to call. With more similar features planned, Jana Dönszelmann…

I’ve been working at Mozilla for eleven years, my golly. I’m still on my third hardware refresh (a Dell XPS I continue to dislike), I’m up to my fourth CEO, and 76 reorgs have happened (well, I know that quite a few things that would normally have counted haven’t been counted there, so it’s probably…

Security updates have been issued by AlmaLinux (idm:DL1, kernel, libsoup, perl-URI, python3.14-urllib3, and webkit2gtk3), Debian (apache2, cifs-utils, haproxy, jq, kernel, and xen), Fedora (aom, chezmoi, chromium, docker-buildx, freeipa, freerdp, GitPython, httpd, jfrog-cli, kernel, knot, libheif,…

So... this is an "icon". It's for, a KDE application made by a great friend of mine, Sebas. You might have seen him in. on a video about some thing turning 30 I spent several days working on this thing. I lost count somewhere after 30 hours. It's a fish covered in disco mirrors,…

Make a map in QGIS 3.44 from open data: style it, label it, build a print layout with legend, scale bar and north arrow, export it. Then the same map by AI.

GeoServer 2.27.7 release is now available with downloads (bin, war, windows), along with docs and extensions. This series has previously reached end-of-life, with this release issued to address an urgent bug or security vulnerability. Please apply this update as a mitigation measure only, and plan…

A student finishes a QGIS exercise, saves the project and sends the file to the instructor. The analysis is complete—but the map is still difficult to share with a colleague, a client or the public. That last step, taking a desktop GIS project onto the web, is increasingly part of practical GIS…

Linus Torvalds has released the 7.3 kernel, as expected. It's Sunday afternoon, and this week I somehow kept my wits together long enough to keep track of the day of the week, so the release isn't randomly delayed. Will wonders never cease? Anyway, nothing very special seems to have happened…

Another new and exciting version of our still-new package myman reached CRAN this morning, and has been built for r2u and on r-universe. The matching Python package has also been updated. The package offers twenty one hundred eighty four “My man …” posts by Kevin Kruse made on bsky during the summer…

A few days ago systemd gained tools which allow you to monitor Varlink traffic. A new Varlink service (io.systemd.VarlinkMonitor) allows you to set up a ring buffer which will get filled with packets containing the traffic which matches the filters you provide. This provides the functionality that…

Let's get this out of the way first - this is a terrible idea! I want my two-factor authentication codes to be easily accessible to me, so I've built a watch app which will display them. That's really convenient for me - but makes for a terrible security posture. Anyone who steals my watch will be…

Yet another way of writing for loops: var_a2_4 = ... if (var_a2_4 < 0x78) { ... do { ... var_a2_4 += 1; } while (var_a2_4 < 0x78); } This extra if is merely there because the compiler wasn't able to prove that the variable didn't start…

Bending is the hardest thing to learn on a harmonica, mostly because you can’t see it. You change the shape of your mouth and throat, and the only feedback is whether the note sounds right, which is exactly what a beginner can’t judge yet. The bending trainer is the screen in Harmonicon for…

Armadillo is a powerful and expressive C++ template library for linear algebra and scientific computing. It aims towards a good balance between speed and ease of use, has a syntax deliberately close to Matlab, and is useful for algorithm development directly in C++, or quick conversion of research…

Let's look at the entire loop from yesterday: u16 spE10; u16 *var_v0_2; ... var_t1_2 = 0x7F; var_v0_2 = &spE10 + 0xFE; do { *var_v0_2 = 0; var_t1_2 -= 1; var_v0_2 -= 2; } while (var_t1_2 >= 0); What's going with the pointer arithmetic here?…

SRFI 278 is now in final status. This SRFI defines procedures on Scheme numbers that aim to improve the portability and usefulness of Scheme arithmetic. These procedures include predicates with extended domains, hyperbolic and inverse hyperbolic functions, the R6RS numeric tower, and…
