netcat ssh via http proxy connect on windows

I really don’t know if this is possible without the use of cygwin for [netcat/corkscrew] operation…

update: appears you can connect “via putty” through an HTTP proxy, and I suppose after that tunnel another local port through so that things like ssh on the command line [via your tunneled port] work.

They also mention that there are some other dedicated solutions for doing this tunneling, don’t know what they are/might be, please leave comments below!

google fiber how to disable wireless wifi

OK if you have the “advanced” interface enabled, basically, go to the wireless tab, and then at the bottom under virtual AP it will list one, click edit by it, then click disable.

Then, there’s *another* sub tab, middle top,there are two links:

 802.11an 5GHz Wireless  802.11bgn 2.4GHz Wireless


You need to click on both separately and disable both separately.

This can also explain how sometimes it is broadcasting with two separate SSID’s!

Yamaha YPG-235 flickering blue screen/audio phase out

If your yamaha synthesizer (in my case

Yamaha YPG-235 )

Has a “flickering” blue LED screen, and when it makes louder noise it fades out, double check your power supply and make sure you didn’t accidentally substitute it with another one that doesn’t give it enough power, should be  1.5A apparently)

TODO get more pictures [?] put in comment on adapter what it gives?


The power supply is a Yamaha PA-150 which can deliver 1.5 A. Which means that any polarity and plug-compatible power supply supplying >= 1500 mA at 12V would work. PA-150 can be found on Amazon (as below) and I am sure other places as well.
