Earlier quoted context omitted.

Because it's Fabrice Bellard. Look at his ouerve, he doesn't bother integrating any of his projects into anything else, or put more charitably, dance to the politics of other peoples' projects. I don't blame him. Contributing to GNU projects as an outsider is a PITA.

> Contributing to GNU projects as an outsider is a PITA. Finally someone who has the guts to write this!!! So true, so true ...

Why would a semi-anonymous comment require guts?

As cool as this is, the title is a bit misleading. This setup requires a "low cost software radio frontend" costing about $2000 and the author is using a high end i7 processor.

Still a very cool use of SDR and probably considerably cheaper than the alternatives.

Very neat. Shame that 'interested companies can contact me'. Would be fun to know how such base-stations - when attached to antenna - can be used to spoof things and perform attacks. Lets hope that comes up at some blackhat conference soon...

Yes, it is a big shame that this is not open source. I wonder how much he plans on making from this?

Perhaps it is GPL license AND commercial software.

While it's a big technical achievement, in a world when companies are talking about 4G LTE bill of materials of $50 [1] for a picostation(roughly 20mhz) and vodaphone setting targets for $100(my guess for a full device) , where does this fit in ?

As a development platform for companies that want to experiment with new features prior to committing to design ASICs to support them, for example.

Considering that this is from Fabrice Bellard, I actually was quite disappointed that this isn't really software-only, i.e. uses the side effect radio waves generated by some standard hardware to do it. Talk about high expectations…

Fabrice?

Not sure what your comment means. Did you want a software EM field?

Actual hacker news on Hacker News!

I like the model Fabrice uses. He picks really meaty, technical projects which most individuals would not attempt alone, if they even think the project is possible. And he comes up with the goods. It would be interesting to know if this model works... umm financially. Very tempting to give it a try if it does.

Unfortunately actual hacks are scanty too!

How many people do you know can do all this. There are a few threads being posted these days about side projects/extra income projects/failed ideas. Nearly 99% of all ideas were designing HTML pages. Simple MVC apps.

How many things related to hard core development do you see these days?

Those people who do real hack work, pretty much keep silent and to themselves. Don't harp, tweet or blog every two minutes.

Wow, it's from Fabrice Bellard of QEMU and ffmpeg fame, excellent.

Not only that, but jslinux, qemacs, tcc. All by himself. He might be THE best software developer on earth!

Don't forget the singlehanded pi computation record. This guy is a serious heavyweight.
