ELC : SpaceX lessons learned
http://lwn.net/Articles/540368
On day two of the 2013 Embedded Linux Conference, Robert Rose of SpaceX spoke about the “Lessons Learned Developing Software for Space Vehicles”. In his talk, he discussed how SpaceX develops its Linux-based software for a wide variety of tasks needed to put spacecraft into orbit—and eventually beyond. Linux runs everywhere at SpaceX, he said, on everything from desktops to spacecraft.

It’s best to develop software with plenty of regular visible evidence. Visibility gives confidence that progress is genuine and not an illusion, deliberate and not unintentional, repeatable and not accidental.
La majuscule sied-elle au réseau ? - Libération par @latrive

« C’est un #outil, comme une bêche. On ne met pas de majuscule à une bêche. »
Mais bien sûr... un « outil »... qu’on peut fabriquer soi-même bientôt ils vont dire !... Quand bien même il ne faudrait pas de majuscule, la manière dont c’est argumenté contribue au grand n’importe quoi de la mise sur le même plan de toute technique, simple ou (ô combien) complexe.

intéressant, ce que dit danah boyd du nom ; elle tient à écrire le sien en minuscule http://www.danah.org/name.html
as Douglas Adams noted, “Capital letters were always the best way of dealing with things you didn’t have a good answer to.” Ever since i was a kid, i was told that the world does not revolve around me, yet our written culture is telling me something entirely different. Why not capitalize ’we’ or ’they’? (Yes, i love the work of bell hooks.)
et
But, this led me on a mental tangent - What’s in a name? What’s its worth? Why is it so valuable that it is to be capitalized? Down this path, i started thinking about names as descriptors versus separate entities. Isn’t a name simply another unique adjective for me? A label? I am not my name; my name is simply another descriptor of me. Should i weight that descriptor as anything more valuable than the other adjectives used to describe me?

Mieux que la fin du monde - la fin de l’univers !
http://www.youtube.com/watch?v=ucNYLsjKaTQ
Ladies and gentlemen," he said, “The Universe as we know it has now been in existence for over one hundred and seventy thousand million billion years and will be ending in a little over half an hour. So, welcome one and all to Milliways, the Restaurant at the End of the Universe!”
The Restaurant at the End of the Universe is one of the most extraordinary ventures in the entire history of catering.
It is built on the fragmented remains of an eventually ruined planet which is (wioll haven be) enclosed in a vast time bubble and projected forward in time to the precise moment of the End of the Universe.
This is, many would say, impossible.
In it, guests take (willan on-take) their places at table and eat (willan on-eat) sumptuous meals whilst watching (willing watchen) the whole of creation explode around them.
This is, many would say, equally impossible.
You can arrive (mayan arivan on-when) for any sitting you like without prior (late fore-when) reservation because you can book retrospectively, as it were when you return to your own time. (you can have on-book haventa forewhen presooning returningwenta retrohome.)
This is, many would now insist, absolutely impossible.
At the Restaurant you can meet and dine with (mayan meetan con with dinan on when) a fascinating cross-section of the entire population of space and time.
This, it can be explained patiently, is also impossible.
You can visit it as many times as you like (mayan on-visit re-onvisiting... and so on-for further tense-corrections consult Dr. Streetmentioner’s book) and be sure of never meeting yourself, because of the embarrassment this usually causes.
This, even if the rest were true, which it isn’t, is patently impossible, say the doubters.
All you have to do is deposit one penny in a savings account in your own era, and when you arrive at the End of Time the operation of compound interest means that the fabulous cost of your meal has been paid for.
This, many claim, is not merely impossible but clearly insane, which is why the advertising executives of the star system of Bastablon came up with this slogan:
“If you’ve done six impossible things this morning, why not round it off with breakfast at Milliways, the Restaurant at the End of the Universe?”

On notera tout de même la proposition de Léa (ci-dessus), qui s’est demandée comment les semences conservées au Svalbard Global Seed Vault pourraient être utilisées, si la population humaine était un jour amenée à disparaître. Son travail à consisté à réaliser des modes d’emploi sans légende : comment planter, faire croître et utiliser les graines.
Le rachat de #Skype par #Microsoft a logiquement fait bouger beaucoup d’électrons. Communiqués officiels en http://about.skype.com/press/2011/05/microsoft_to_acquire_skype.html ethttp://www.microsoft.com/Presspass/press/2011/may11/05-10CorpNewsPR.mspx et, pour un résumé et une mise en perspective, http://www.guardian.co.uk/technology/2011/may/10/microsoft-confirms-skype-deal
Il est amusant de voir des milliers de neuneus découvrir soudain que Skype, c’est mal. Maintenant que le logiciel ultra-fermé et complètement privateur est acquis par le Satan de Redmond, on lui trouve tout à coup bien des défauts.
La vérité est que Skype était un logiciel non-libre depuis toujours. Le code source n’est pas disponible (pour éviter qu’on y trouve leurs saletés comme le fait que Skype enrôle des clients comme « supernodes » sans les prévenir http://www.velocityreviews.com/forums/t727931-skype-fixed-supernodes-list.html) et Skype n’utilise que des protocoles à eux, non documentés, de façon à éviter que quelqu’un ne développe un « compatible Skype ».
Donc, si le rachat de Skype par Microsoft a un seul avantage, c’est bien de permettre de rappeler qu’il existe (au moins un) protocole ouvert de téléphonie sur IP, #SIP, et qu’il existe (au moins un) protocole ouvert de messagerie instantanée, #XMPP. Tous les deux ont de multiples mises en oeuvre en logiciel libre et de nombreux serveurs existants, gratuits et communautaires, ou bien commerciaux (ainsi que la possibilité d’installer le sien sur sa machine).
Tiens, pour varier les opinions, un article relativement pro-Skype : http://www.jpetazzo.dotcloud.com
Et mes récits de mes débuts en SIP :
