Thunderbird:OpenPGP:Migration-From-Enigmail - MozillaWiki
▻https://wiki.mozilla.org/Thunderbird:OpenPGP:Migration-From-Enigmail
Le passage à la version 78 de Thunderbird avec la suppression du module Enigmail « remplacé » par une gestion intégrée de GPG est une catastrophe (en tout cas avec Windows)...
GnuPG vs. RNP and key storage
Thunderbird no longer uses the external GnuPG software. Previously, all your own keys and the keys of other people were managed by GnuPG, and Enigmail offered you to view, use and manage them. Now that Thunderbird uses a different technology, it’s necessary to perform a migration of your existing keys from GnuPG into Thunderbird’s own storage (inside the Thunderbird profile directory). Thunderbird will uses its own copy of the keys, sharing your keys between Thunderbird 78 and GnuPG currently isn’t supported. (Exception: There is an optional mechanism to use GnuPG with smartcards. It’s disabled by default and needs more testing.)
...ce qui entraîne que si vous gérez vos clé GPG avec GnuPG, celles-ci ne sont plus disponibles automatiquement sous Thunderbird. Et régulièrement (environ toute les semaines ?) il faut refaire l’import de votre clé privée dans TB...
Pourtant :
Experimental in 78.0, but stable in the near future
If you’re reading this before OpenPGP has been declared as a stable feature in Thunderbird 78.x (expected for the 78.2 release end of August 2020), then please consider to stay with Thunderbird 68 and Enigmail for another while, especially if you depend on the security of OpenPGP and are worried about correct behavior.
...mais on est maintenant à la 78.4 et c’est toujours autant n’importe quoi !
...et pire encore sur la FAQ de TB 78 :

J’ai besoin d’utiliser GnuPG et Thunderbird en parallèle, puis-je synchroniser mes clés ?
Non. Pour l’instant, Thunderbird utilise sa propre copie des clés et ne prend pas en charge la synchronisation des clés avec GnuPG. L’exception est le mécanisme proposé pour les cartes à puce, qui pourrait servir à utiliser les clés personnelles gérées par GnuPG.
pfff... on est au summum du anti-user-friendly là !

Notes pour les Windowsiens·ennes utilisateurs·trices de Gpg4win (le GUI de GnuPG pour Windows) : la modification d’expiration des sous-clés d’une clé privée n’est pas gérée par Kleopatra : il faut donc passer par la version en ligne de commande de Gnupg.
...sauf que le répertoire utilisé comme HOME par la commande gpg ... (C :\Users\toto\.gnupg) n’est PAS celui utilisé par Gpg4win (C :\Users\toto\AppData\Roaming\gnupg) ET que les fichiers de lock ne sont pas compatibles entre les 2 implémentations !
La soluce est donc :
– aller dans le HOME de gpg4win (C :\Users\toto\AppData\Roaming\gnupg) et renommer tous les fichiers *.lock
– lancer gpg en ligne de commande en lui spécifiant l’option --homedir ...cheminAppData...
Ce qui peut donner en utilisant un terminal « unix-like » tel que gitbash :
#lister les clés privées disponibles
gpg --homedir /c/Users/toto/AppData/Roaming/gnupg/ -K
#passer en mode interactif pour édition de la clé ma_cle
gpg --homedir /c/Users/toto/AppData/Roaming/gnupg/ --edit-key ma_cle (...et après on s’étonne de la sous-utilisation de GPG par le grand public !)

pyllyukko/user.js: user.js — Firefox configuration hardening
▻https://github.com/pyllyukko/user.js
A user.js configuration file for Mozilla Firefox designed to harden browser settings and make it more secure.
Main goals:
– Limit the possibilities to track the user through web analytics.
– Harden the browser against known data disclosure or code execution vulnerabilities.
– Limit the browser from storing anything even remotely sensitive persistently.
– Make sure the browser doesn’t reveal too much information to shoulder surfers.
– Harden the browser’s encryption (cipher suites, protocols, trusted CAs).
– Limit possibilities to uniquely identify the browser/device using browser fingerprinting.
– Hopefully limit the attack surface by disabling various features.
– Still be usable in daily use.

Think about how many startups are formulated within the minds of new computer science majors at the dorms of Cal.

The days of disruption, radical token models, value capture theses and spreading crypto gospel to anyone who will listen are over. Make room for #blockchain transformation, value creation and #adoption. Maturation is a good thing.Despite the shift, what was once the cypherpunk’s vision of the future — an internet of value, sovereignty, privacy and micro-payments — is still within our reach. The ICO model was tragically flawed. New business and social coordination models were sold ahead of the technology and cultural shifts. Token engineering value capture was hamstrung by the limitations of early cryptonetworks (try computing anything on-chain). However, nothing trumps the blaring noise of our crypto gospel choir than the average Internet user.They don’t care about sound money policy, (...)

Gary Pedretti, Professional Scrum Trainer, Scrum.orgI often see User Experience (UX) Designers struggle to align focus, work, and approach with Scrum Teams building increments of product in iterations of 30 days or fewer. Common concerns and questions I hear include:“Developers aren’t really interested in the user, they just want to build.”“I’m trying to work side-by-side with the team, but I’m always a bit ahead of them, so what should we talk about in our Daily Scrum?”“I don’t work in sort cycles, or tactically. My work is strategic.”“Why don’t developers use my design artifacts and decisions? Why do they never go back and refactor for good design? Why do I feel like I never have any influence?!?!”These challenges often result in tenuous relationships between UX Designers (UXDs) and Scrum Teams — (...)

Estimating #agile Projects with User Stories

How to Estimate anAgile Project With User StoriesEstimating software projects is hard. Early on in the development process, you can’t precisely define the scope of a project. Because inevitably, the scope will change after development kicks off, since the team will have learned more about the project and its context by then. Still, teams have to estimate the resources they need for a project, at least approximately, before getting started.So, how should you tackle this, then?The traditional approach is to enter an analysis phase where you create a detailed specification of what needs to be built. But like we said, the scope of a project isn’t exactly clear before development begins. For that reason, analysis isn’t the best approach.What is a user story?Simple but powerful, a user story is a (...)

A while ago I decided as a hobby project to improve the User Experience of PSprices.com. I love the price monitoring product that they build, but the UX is quite a mess. As I’m focused on UX and not on #design, I tried to keep the design and branding unchanged.Normally I would never make any changes to a website withouth analysing the existing usage data. In this case, as I’m not involved with the website, I had to make some assumptions.Before and afterMy main focus in the new UX is to help the user reach his goal of: Buying the game now when the price is low, or buying it later when the price drops more. By reducing unnecessary info, improving the flow through the page I created a UX design that is very likely to perform better in reaching the user’s goal (and the business goal of the (...)

At its best, virtual reality is one of the most immersive forms of entertainment.

It begins with the disconnect between what the eyes see and what the brain processes, or dissonance.

Everything from the packaging to the setup instructions was laser-focused on ensuring I could get these products up and running myself.The attention to detail that the companies had put into the onboarding process was very remarkable.

Packaging is how applications look and feel.In creating applications, design matters. It is a crucial part of packaging technology.Design guides user behavior and action.
