Just buy a bunch of tp-link, replace its firmware with openwrt and do whatever you want: mesh, wds, etc...

Even if the hardware might not be as robust as a cisco, just multiply the number of units you buy. It's the same principle of RAID (redundant array of inexpensive discs). Just build an RMIR (redundant mesh of inexpensive routers)

Individual coherence makes collective incoherence.

It is logical to not migrate as it costs and nobody uses it yet (but me). It does not add a think to your service, except if your end-user is a technical one (that for some reason, want IPv6). However, the logical "not migrate" movement creates a great incoherence when it introduces extra costs in order to overcome the lack of IPv4 when bad times comes. At that time, CFO will start to worry when the cost of IPv4 get skyrocketed.

So, if you migrate now and nobody does, you gain nothing. It only costs. If you do not migrate now and everybody else does, you gain as you postpone an investment without immediate return. When you migrate, it will be easier and cheaper. Now, it nobody migrates, we get doomed.

Who migrated until now are just people that like new technologies because they are new, even if they are worse. I migrated to IPv6 but it introduced extra lag as my ISP does not provide it and I'm using a tunnel.

There must be some material that will reflect the laser beam. Isn't it necessary to generate the laser anyway? What about some lens shield that would use refraction with the help of some silver color? Ideally, it would be cool to see some counter-attack based on reflecting it back to source, varying a little bit around it. There must be something interesting to destroy around a laser cannon.

+ - First Alpha of Qt for Android Released-> 1

Submitted by Anonymous Coward
An anonymous reader writes "In the wake of the Nokia's announcement that it will be cheerfully throwing its existing developer community under a bus by not offering Qt for Windows Phone, a project to implement Qt on Android has announced its initial alpha release. Necessitas project lead Bogdan Vatra writes, 'I had a dream that one day, I'll be able to deploy existing Qt software on any Android platform. I had a dream that one day, all Qt applications will use system wide shared Qt libraries. I had a dream that one day, all Qt applications once compiled and deployed to one android platform, will run on any other newer android platform and will last for years without any recompilation. I had a dream that one day, I'll be able to create, manage, compile debug and deploy Qt apps using a first class citizen IDE. Now, those dreams become reality.' The Necessitas wiki offers some documentation on Qt for Android. A demo video of Qt for Android in action is also available."

OK, OK... now tell me if it makes any difference for your browser/app if the certificate is generated by some respected CA or a crappy one. There is no "trust level", just yes or no. Any CA can provide ANY certificate for ANY host. You control one CA, you control them all. If you can make any accepted CA generate the desired certificate, by bypassing identity validation, by political force, by social engineering, by whatever, SSL is just useless. It just protect you from someone a little more "powerful" than yourself. Correct me if I'm wrong but many respected CA can be persuaded by big countries, isn't it? How I love my PGP.

Money is the root of all evil, and man needs roots.
