IPv6 c'est parti!

L'ICANN a commencé à ajouter les adresses IPv6 aux DNS root pour les TLD .jp (Japon) et .kr (Corée). Celà signifie que dans ces pays il devient possible d'utiliser IPv6 de manière publique et transparente...

...pour peu que les utilisateurs disposent de systèmes compatibles!

Je ne sais pas bien ce qu'il en est dans ces pays, mais le prochain TLD concerné est le .fr! Et en France, il reste beaucoup de vieux Windows et autres qui ne savent certainement pas gérer le IPv6 en standard... ça va donc pas être tellement transparent que ça.

Alors on pourrait dire que c'est pas grave puisque IPv4 reste disponible, sauf que... si on déploie IPv6, c'est parce qu'on arrive rapidement à épuisement d'adresses IPv4 dans les pays concernés! :|

Que va-t-il se passer? Impossibilité de connecter de nouvelles machines qui seront accessibles à tous (en particulier ceux qui ne peuvent encore utiliser IPv6)? Traffic d'adresses IPv4 avec inflation supérieure au pétrole?

A propos, ça fait des années qu'on aurait du passer à IPv6 pour régler le problème du nombre d'adresses IPv4 trop limité... au lieu de ça on a rusé en instaurant le Classless Inter-Domain Routing (qui permet d'utiliser les dernières miettes d'adresses IPv4 disponibles) ou HTTP 1.1 (qui permet d'héberger plusieurs serveurs web sur la même adresse IP)... mais il est inévitable de finir par se retrouver au pied du mur!

Lors du dernier Networld+Interop, je me rappelle avoir entendu que le Pentagone menait une politique volontariste pour être 100% opérationnel IPv6 en... 2008 si tout va bien!

J'ai un léger préssentiment de bordel à venir... |-| Ceci dit, une petite opération "migration IPv6 au pas forcé" pour faire suite aux opérations "An 2000" et "Euro", ça ferait pas de mal au marché informatique en général!! Gniark! :>>

Pilotime / Canal Sat

Je ne crois pas l'avoir déjà dit ici, mais il y a quelques semaines, j'ai craqué et j'ai pris un abonnement satellite (je crois que j'étais en manque de LCI, MCM et Ouï FM ;D), Canal Sat en l'occurrence parce que l'installation de la parabole collective pour l'immeuble était gratuite pour peu que j'arrive à convaincre au moins deux de mes voisins... ;)


Depuis ce jour j'entretiens une relation d'amour/haine avec ce terminal numérique à la fois génial et pitoyable qu'est le Piltotime! 8|

A journey into WiFi

I'm on a train right now (typing this into TextPad) and I'm sort of realizing that the WiFi ubiquity I have been experiencing for the past few weeks was actually an illusion! :-/

It all started last month when I bought a new laptop with built in WiFi. It's the kind of gadget you just can't leave unused, even if it's hidden deep inside the machine. You know it's there and you just gotta check it out.

I thought the cheapest way to give it a try was to buy an USB WiFi adapter and plug it into my desktop. So I went for a Netgear USB key and quickly set up an 'ad-hoc' network between my laptop and my desktop. (For the record, the laptop uses an Intel "centrino family" WiFi chip.)

The other way to go would have been to buy a standalone WiFi access point, maybe even one that's merged into an ADSL modem. This would be called 'infrastructure' mode. I thought ad-hoc and infrastructure were basically the same, except I would not have had to turn on the desktop to act as an internet router everytime I wanted to access the Internet from my laptop. So I decided I'd simply go the cheap way.

Well... I was wrong.

Sendo X unveiled

Sendo X

Sendo has unveiled more of its Sendo X in a press conference today. Let's tell it as it is: that smartphone totally rocks! It's even better than what we could expect from previous announcements.

Of course, in this industry, product cycles are very short, so it's only going to be a matter of months before someone (Nokia?) comes out with something better (I mean a better smartphone, not an experimental device like the 7700! :>>).

The Sendo X should be priced around 500 € (unsubsidized) and actually includes pretty much everything you could wish from a smarphone: compact, true phone form factor, normal keyboard, color display (176*220*16), integrated camera with flash, recording and playback of video (15 fps), sound, music, support of standard formats (mp3, mpeg...)

And of course, it runs on Symbian + Series 60 with Java/MIDP support.

One thing I was pretty unsure of until now, was if it was possible to connect a stereo headset for mp3 playback as an alternative to the built in accoustic system. Not only is it possible, but the headset is provided in the box! B)

The other good news is that the device supports SD cards up to a 1GB capacity and beyond. That's exactly what you need to store the mp3s you want to listen to and all those sound/video recordings you're going to make. Even better: the SD cards are hot swappable! B)

Actually, the only drawback I could find so far is the lack of support for SD/IO.

Also, I had written before that many pocket devices were going to converge soon and this time has definitely arrived (it only lacks an emebedded GPS! :> ) However, I stated that we'd still want PDAs with larger screens and a pen interface to take notes.

Well... the fact is you don't need to take notes no more! Just record or picture the info! You'll process it later anyway. ;) Moreover, when you really need to enter text (for email for example) you can always use T9. (That is for western countries with limited alphabets... :>>) However, for massive emailing, you'll probably want to get the external keyboard accessory. Plus, stylus technologies aren't so reliable anyway!

I am glad I managed to wait that long to replace my aging PDA and phone, because the SendoX is definitely going to replace them both at the same time, with increased efficiency on all my previous plans! ;D

Can't wait! Gotta check availability in France. :)
