Various updates to my web authoring and publishing tools
▻https://etienne.pflieger.bzh/a-ecrit/various-updates-to-my-web-authoring-and-publishing-tools.html

I just released several updates to the little softwares I created. I built them for my own usage, but I’d be curious to know if another one tried them or even use them.

Time flies and habbits change. When I began to write code, it was mostly in PHP. Later I switched to ugly shell scripts and more robust python scripts or apps. For the last eight years I gradually, but surelly move to #ruby for everything. So don’t be surprised if more and more of my tools are in ruby.

All the following projects are hosted on my own git server.

#Fronde v0.5

Biggest changeset here. This release took me most of the time. Check the related blog post for the details.

Je suis un grand consommateur de flux #RSS (ou Atom pour être techniquement complet) et ce depuis bien longtemps. L’enshittification actuelle du #Web me rend parfois la vie désagréable, mais contre toute attente les flux restent une valeur à peu près sûre du Web de qualité (oui, je sous-entends qu’un site d’actualité qui n’en propose pas n’est pas de qualité).

Bref, ça m’arrive d’être en galère pour pouvoir suivre des sites que j’aime depuis mon lecteur de flux. Il existe des centaines de solutions diverses et variées pour générer des flux RSS ou Atom, mais rien de tel qu’une petite problématique comme ça pour se faire un bricolage personnel.

J’ai donc ressorti Nokogiri et me suis affûté un petit script personnel. Il est pour l’instant conçu pour générer les quatre flux Atom suivants  :

This release also continues the stability work.

All changes are visible in the git log, but here are the most interesting changes:

Features

Replace r18n-core dependency by more common i18n gem. Add a new rake task to generate a Fish shell completion file. Detect orphaned keywords in the site:clean rake task, to allow you to remove useless files. Add a new rake task to build a single file instead of the whole project.

Fixes

Fix build time regression by using a keywords cache directly exposed to #Org internals. Correctly expose the verbose option to the right commands in the CLI help messages. Never automatically eval code blocks, as it clearly opens a security flaw. Never use the throbber in verbose (...)

#RVM and #fish shell
▻https://etienne.pflieger.bzh/a-ecrit/rvm-and-fish-shell.html

Since the end of the summer, and more specifically following a post by Julia Evans about the fish shell, my curiosity was once again triggered by this shell. I know it by name since a long time, but never take time to test it. Or last time I did it, something I did not expect happen, and I was probably less comfortable with the whole shell stuff. Anyway, I stayed on bash and then zsh.

Clearly, all the time I spent using zsh, and configuring it, make me a lot more aware of what a shell really is, what happen under the hood, etc. So after reading Julia Evans article, I tried the fish shell again… and actually loved it. So much that after only 3 days or so, I decided and successfuly switch to fish as my session shell.

It took some more time to migrate my most used tools to it. RVM was (...)

#Ruby_Bridges: the six-year-old who defied a mob and desegregated her school | Race | The Guardian

his year, Ruby Bridges saw some newly discovered video footage of her six-year-old self and was terrified for her. The footage was from 14 November 1960, a day that shaped the course of Bridges’ life and – it is no exaggeration to say – American history. Not that she was aware of it at the time. On that day she became the first Black child to attend an all-white primary school in Louisiana.

Looking at images of Bridges’ first day at William Frantz elementary school in New Orleans, she is a study in vulnerability: a tiny girl in her smart new uniform, with white socks and white ribbons in her hair, flanked by four huge federal agents in suits. Awaiting her at the school gates was a phalanx of rabidly hostile protesters, mostly white parents and children, plus photographers and reporters. They yelled names and racial slurs, chanted, and waved placards. One sign read: “All I want for Christmas is a clean white school.” One woman held up a miniature coffin with a black doll in it. It has become one of the defining images of the civil rights movement, popularised even further by Norman Rockwell’s recreation of it in his 1964 painting The Problem We All Live With.

Have you ever needed to download and save an image in your Ruby application? Read on to find out how.Plain old RubyThe most popular way to download a file without any dependencies is to use the standard library open-uri.Kernel#open is a method that you can use to open files, streams, or processes to read to or write from. For example, you can open a file and read its contents with the following code:open("./test.txt") do |file| puts file.readendopen-uri extends Kernel#open so that it can open URIs as if they were files. We can use this to download an image and then save it as a file.To do so, we first require open-uri then use the open method to access an image URL. We can then open up a file and write the contents of the image to the file. Open up IRB and try the (...)

Italie : mystère sur la mort d’un témoin dans un procès contre Berlusconi
▻http://www.lefigaro.fr/flash-actu/italie-mystere-sur-la-mort-d-un-temoin-dans-un-proces-contre-berlusconi-201

Le récent décès de l’ex-mannequin Imane Fadil, témoin dans des procès contre Silvio Berlusconi et ses soirées « #bunga-bunga », est entouré de mystère, la jeune femme semblant avoir été empoisonnée avec des substances radioactives, rapporte samedi la presse italienne.

Imane Fadil, 33 ans, avait été hospitalisée le 29 janvier dans les environs de Milan (nord) et elle est décédée le 1er mars dans le même établissement, a indiqué le procureur de Milan Francesco Greco, annonçant l’ouverture d’une enquête.

Selon le Corriere della Sera, l’hôpital où se trouvait la jeune femme a procédé à des examens pour tenter de comprendre quelle était la cause de la détérioration de sa santé et, n’ayant rien trouvé, a envoyé des échantillons à un laboratoire spécialisé de Pavie (nord). Citant des sources non identifiées, le quotidien écrit que les résultats sont parvenus le 6 mars, cinq jours après le décès de la jeune femme, et évoquent « la présence d’un mélange de substances radioactives qu’il n’est pas possible de trouver normalement dans le commerce ». Selon Paolo Sevesi, l’avocat d’Imane Fadil, cette dernière lui aurait confié « sa crainte d’avoir été empoisonnée », indique pour sa part l’agence AGI.

« Je suis navré quand une personne jeune meurt. Je n’ai jamais connu cette personne et je ne lui ai jamais parlé », a affirmé pour sa part Silvio Berlusconi au cours d’une réunion électorale dans la région de Basilicate qui doit élire son président demain. « Ce que j’ai lu concernant ses déclarations m’a toujours fait penser qu’il s’agissait de choses inventées et absurdes », a-t-il ajouté. Dans le dernier procès en cours de la série Ruby, dans lequel Silvio Berlusconi est accusé de subornation de témoin et qui est toujours en cours, le tribunal avait rejeté en janvier la demande d’Imane Fadil de se constituer partie civile.

When your team has been asked to move fast and break things, methodological purity can fast give way to sprint-speed pragmatism. However, this phrase — once the credo of Facebook — doesn’t mean we can take risks in the QA department. It’s really an admonition for us to open our eyes to new opportunities instead of closing them and praying that things will stay the same. A kind of rallying cry to be disruptive and try (and discard, if necessary) new things quickly.What’s all this got to do with testing and QA?Quite a bit. In our experience, QA is one of the slowest moving disciplines across the development landscape. This goes for both the supply side and the demand side of the market.
