The Makers Phenomenon and Future Mobiles

Locally we have the Nottingham Hackspace in recent years seemingly appear from nowhere and continue to enthusiastically expand (with friendly cross-over with NLUG). Around the world, “Makers” are gaining greater prominence in the news media (including dedicated magazines such as Makezine). All the more so with the phenomenal success of the Raspberry Pi aided by . . . → Read More: The Makers Phenomenon and Future Mobiles

Gentoo kernel 3.6.11 webcams, V4L, UVC, video: kernel config

For those of us adventurous enough to upgrade to the Gentoo kernel 3.6.11 using their own custom kernel config… Beware that the config spec for the video modules and webcam modules including all of the USB UVC/video have been moved in the config hierarchy and may well need reenabling:

Unravelling an Enigma

What a blazingly good fun day at Bletchley! A ‘few’ pictures of the day are shown below (hi-res versions are available on request).

Well… Some of us were ‘keen’ and so we were there in the queue for when the gates opened at 9:30am. Various en-route txts from the rest of our group coordinated our . . . → Read More: Unravelling an Enigma

MTU – MSS – Kernel Compile and Networking Gem

Unbelievably, this is still a problem across the internet!

If your connection through to the internet is less than 1500 (bytes) MTU, or if the destination you wish to connect to is less than 1500 MTU, and there is a “brain dead” ‘block all ICMP‘ at that far end or anywhere else along the route . . . → Read More: MTU – MSS – Kernel Compile and Networking Gem

kernel-3.3.8-gentoo to kernel-3.4.9-gentoo

(This detail should not be a problem for you if for Gentoo you are using the default ‘genkernel‘.)

 

Here’s a ‘minor’ update foible to watch out for on Gentoo when moving from a compiled kernel-3.3.8-gentoo to kernel-3.4.9-gentoo and running Shorewall…

There’s a few new kernel config options and at least some of them must . . . → Read More: kernel-3.3.8-gentoo to kernel-3.4.9-gentoo
