An Initial Look at Grafting

I’ve said it before and I will say it again… a lot, I’m not an expert. This is my initial look at Grafting without having done it yet.

Just imagine having one tree produce peaches, plums and cherries or 3 different kinds of apples or a pecan being able to bear nuts without requiring 2 separate (male and female) trees or an established tree giving a jump start to production.

Grafting is the process of attaching a cutting of one tree to a rooted tree either as a limb, replaced at or just above root stock. This is done by exposing the cambium layer/vascular tissues of two different trees or exposing the cambium layer on the primary and harvesting a bud of another then joining the two together with a hormone and grafting compound (wax, rosin, natural oils) followed by taping/wrapping to protect the exposed woods.

The primary techniques I have found are Whipping, Budding, Cleft and Stubbing. Other techniques I have read about seem to be variations or combinations of those identified.

While not set in stone this doesn’t work with every species and typically only works if the 2 plants are from the same family.

Advantages of Grafting are use of disease-resistant rootstocks, small footprint diversity, and for having both male and female of one species on one graft for plants that require pollination in order to flower, bear fruit or nuts.

If you have some good knowledge on grafting, I’d love to hear from you or even interview you so please contact me via email mrredbeard AT MickRed dot com or call and leave a message at (747) 333-8145

More to come…..

Terms

Scion – a cutting from a woody plant

Rootstock – roots from an established plant

Grafting compound – sealant/protector

Grafting wax – bee’s wax/paraffin/tallow

Rooting Hormone – Salicylic acid that can be obtained from willow buds (highest and most effective concentration)/bark/leaves and is the active ingredient in Aspirin. Supposedly if you add honey it acts as a antiseptic/antibacterial that aids rooting and grafting.

Sony Google TV Box Hack Research

Sony NSZ GT1
Sony NSZ GT1

This project is still in the first stages of research.

After waiting forever for Google to make negotiations successful and continue to workout bugs some media sources still do not work such as Hulu.

I have a Sony Google TV box model NSZ-GT1. My box has the 20120917 update installed which may not be possible to downgrade.

Hack process involves downgrading and installing modified update files.

Notes

Looks like someone leaked HC for the Sony NSZ-GT1

Quote:
This is a HC update with root for the NSZ-GT1 GoogleTV Bluray Player
http://www.multiupload.com/1SU4ZPXQP5

from: http://www.reddit.com/r/GoogleTV/comments/lilis/hc_update/

This build works great and contains root (if you remount adb).

Install Instructions:
1.) Download update and place on a thumb drive (at least 512MB capacity) in the root directory of the device.
2.) Plug thumb drive into NSZ-GT1.
3.) Enter Sony Recovery by first unplugging the power from the box, then while holding the power button plug in the power cable. Continue to hold the power button until the Sony Recovery menu displays.
4.) Choose “System update with USB” option (option #3).
5.) The device will ask you if you would like to upgrade, choose 1 for yes.
6.) The device will present a progress bar and will reboot when completed. (Do not turn off the box during this period)
7.) Enjoy HC on the sony NSZ-GT1

Thanks,

Turns out there is a check in place to limit browser and flash from accessing Hulu/CBS/NBC/ABC. (1)

Update.zip exploit (1)

package_list_;cd tmp; cd mnt; cd diskb1; sh t.sh; .zip
/package-updater.sh -l 0 -p /tmp/mnt/diskb1/package_list_;cd /tmp;cd /mnt;cd /diskb1;sh t.sh;.zip

“The command above involved a t.sh bash script (to meet filename size limitations) which spawned a shell over UART and telnetd. From there we proceeded to dump the recovery file system.”

Unfortunately this exploit was patched in the 7/2011 update

 

Reboot
Apply Update from USB (update.zip)
Wipe data/factory reset
Wipe cache partition
All update files provided are RSA verified before the box attempts installation
