In “The Art of the Deal,” Tony Schwartz helped create the myth that Trump is a charming business genius. Now he calls him unfit to lead.

+David Weekly dream on; the message is a pull request for the upstream net-next tree for Linux; that's a step away from kernel.org. OnHub better be tracking kernel.org to see it quickly.

Toke is also making good progress on air-time fairness, which is cool.

Dave's work is vital, and your support appreciated....
 
https://www.gofundme.com/savewifi - I am one of the people that made wifi what it is - open, free, for anyone to use, any way they wanted - and it seems today  like every government agency and carrier - and even those making the chips - wants to kill it.

I spent the last 2 years of my life designing algorithms to make wifi a lot better than it is today, only to find out a few months back that both the FCC and the European commission, planned to make the results of my life's work, illegal for ordinary people, to install.

The CeroWrt project's letter to the FCC on how to better manage the
software on wifi and home routers vs some proposed regulations is now in last call for signatures. The final draft of our FCC submittal is
here:

https://docs.google.com/document/d/15QhugvMlIOjH7iCxFdqJFhhwT6_nmYT2j8xAscCImX0/edit?usp=sharing

And in PDF format: http://huchra.bufferbloat.net/~d/fcc_saner_software_practices.pdf

The principal signers (Dave Taht and Vint Cerf), are joined by many
network researchers, open source developers, and dozens of developers of aftermarket firmware projects like OpenWrt.

Prominent signers currently include:

Jonathan Corbet, David P. Reed, Dan Geer, Jim Gettys, Phil Karn, Felix
Fietkau, Corinna "Elektra" Aichele, Randell Jesup, Bruce Schneier, Eric S. Raymond, Simon Kelly, Andreas Petlund, Sascha Meinrath, Joe Touch, Dave Farber, Nick Feamster, Paul Vixie, Bob Frankston, Eric Schultz, Brahm Cohen, Jeff Osborn, Harald Alvestrand, and James Woodyatt.

If you would like to join our call for substituting sane software
engineering practices over misguided regulations, the window for
adding your signature to the letter closes at 11:59AM ET, today,
Friday, 2015-10-08.

Sign via webform here: http://goo.gl/forms/WCF7kPcFl9

We are at approximately 170 signatures as I write.

Grrr.... Telemarketers no longer even do us the courtesy of a "live person"....

Phone rings.  I answer: "Hello".
Phone replies, with clearly an automated voice: "Hello, this is Ray".
I don't say anything.
Phone says: "Are you there?"
I don't say anything for a couple seconds.
Phone hangs up.

The pieces fall into place. Now if we can get everyone to pay attention...
 
30x reduction in wifi latency, 5x improvement in throughput on a three station test. #bufferbloat is soon to be eradicated on at least some linux drivers. https://blog.tohojo.dk/2016/06/fixing-the-wifi-performance-anomaly-on-ath9k.html

$ lsmod | grep ath9k >/dev/null && echo "Attention got!"
Attention got!

Yep. I'm definitely paying attention.. In fact I feel the onset of a 'make-kpkg' coming on :-)

I like Vint's quote best: “We can't afford to let any part of the Internet's infrastructure rot in place." For the sake of a secure end to end Internet without bufferbloat, it is essential that systems be maintained and upgraded over the life of a device. They cannot be allowed to "rot in place", or innovation will die.

I love frequent security updates too. However, I want to keep my Personal Computer. The one where I the person is in charge when updates are applied.

Lets separate the security necessary updates from the frills and feature additions, that serve the company more then the user. This constant changing software landscape of the web and mobile based apps (incl. Chrome, Firefox, etc.) with auto updates that are not security relevant are a menace.

Stock firmware on almost all home routers is insecure, buggy, bufferbloated and obsolete at shipment and has no secure update stream. Tell me again, FCC why I should tolerate this in my house????
 
Such a rule is potentially disastrous from so many angles -- security, privacy, bug fixing, new applications -- on and on. This one must be stopped.
An anonymous reader writes: Hackaday reports that the FCC is introducing new rules which ban firmware modifications for the radio systems in WiFi routers and other wireless devices operating in the 5 GHz range. The vast majority of routers are manufactured as System on Chip devices, with the radio m...

+Brian Fitzgerald it is the opinion of many that the number one threat to the Internet is stale code.  The number one thing keeping the stale code in place are rules like the FCC one.  It therefore follows that the FCC is the number one threat to the Internet.  If the FCC were a foreign power, we'd be carpet bombing them.

This is so true, though I believe there are other solutions. Once I was a window system expert; now, my answer is I'm not and others are experts. Once I was an HTTP expert; now, don't ask me for my opinion of where it is, and so on. Experts should reinvent themselves periodically, and never stay the expert for too long.... Life is more fun that way, anyway.
 
Food for thought, especially for all us who are experts in their field...
