An Initial Look at Grafting

Grafting Image - www.ces.ncsu.edu
Grafting Image – www.ces.ncsu.edu

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.

Interesting Finds Number 2

Tonight while googling some terms I ran across Daniel Bingham’s website http://www.theroadgoeson.com. This guy seems pretty cool and his website covers topics that I am interested in such as permaculture, programming to include game engine development and web design. The website isn’t perfect and has some broken links but interesting.

Funny enough I have the same Refactoring book pictured on the coding link. Its about the use of existing code.

Game Engine is called Middle Earth Mud and is described as “a multi-user dungeon written in C++, designed to be as flexible for in game building as possible”.

Opensource CAD Software

Archimedes OpenCAD
Archimedes OpenCAD

Archimedes is a free and opensource CAD software. The interface is comfortable, fairly easy to use and is similar to commercial platforms. Exportable formats are svg (vector), pdf, xml and arc which is Archimedes’ native format. The downside is that documentation seems to be lacking and I maybe wrong here but there doesn’t seem to be a way to change the unit of measurement. With that said I still love it and will be using it.

You can learn more and download Archimedes here http://archimedescad.github.io/Archimedes/

Combine 2 or more xml files, sort, dedup and display with php

Want to combine 2 or more xml/rss files with php? This commented code should get you started.

The 2 xml files will need to be structured the same in order for this to work without adding more code. The 2 in this example are from the same source with different filters selected. This allows me to sort, filter and dedup using my own methods. You can then re-create the xml or simply display it on the screen like the example does below.

If you still need help feel free to comment below.

Code and Example below

<?php
//Sort Function by title
function sortFunction( $a, $b )
{
return strtotime($b["title"]) - strtotime($a["title"]);
}

$urllist = array();
//Define new xml files here by adding a new line with different urls
$urllist[] = “http://www.instructables.com/tag/type-question/rss.xml?count=100&sort=RECENT”;
$urllist[] = “http://www.instructables.com/tag/type-question/rss.xml?count=100&sort=UNANSWERED”;

//Loop through urllist array adding each item to one multidimensional array
//Define array before populating
$items = array();
foreach($urllist as $url)
{
$feed = simplexml_load_file($url);

//these item names are the child names in the xml
//channel is the wrapper in the xml
foreach($feed->channel->item as $item)
{
$items[] = array(
‘link’ => (string)$item->link,
‘image’ => (string)$item->imageThumb,
‘title’ => (string)$item->title,
‘pubdate’ => (string)$item->pubDate,
‘author’ => (string)$item->author
);
}
}

//Sort by Title
usort($items, “sortFunction”);

//Remove Duplicates
$items = array_map(“unserialize”, array_unique(array_map(“serialize”, $items)));

//Loop through the list and display them
$ictr = 0;
foreach ($items as $item)
{
echo “<div style=’float:left; width:200px; height:300px; margin-right:15px; text-align:center;’>”;
echo “<a href='” . $item[‘link’] . “‘ target=’_blank’>”;

if(strpos($item[‘image’],”defaultIMG”))
{
echo “<img src=’http://www.instructables.com/static/img/footer/footer-robot.png’ />”;
}
elseif(strpos($item[‘image’],”com”))
{
echo “<img src='” . $item[‘image’] . “‘ />”;
}
else
{
echo “<img src=’http://www.instructables.com” . $item[‘image’] . “‘ />”;
}
echo ‘<br />’ . $item[‘title’] . ‘<br />’;
echo ‘By: ‘ . $item[‘author’] . ‘ On ‘ . $item[‘pubdate’] . ‘</a></div>’;
}
echo “<div style=’clear: both;’>&nbsp;</div>”;
?>

Microwave Deathray

Magnetron
There is something called a Magnetron, not to be confused with Megatron,  inside your microwave. This is the primary component that vibrates the molecules of what you are heating in your microwave to generate heat. Mmmm in the words of Jim Gaffigan Haaaot Pocket!

Ok so it’s not necessarily a death ray but I wouldn’t want to put my junk in front of one. Ever heard of a herf gun? A herf gun is a directed energy weapon. Boeing’s CHAMP recently put on a show taking out targeted computers using one. Supposedly a crude herf gun can be built attaching a waveguide or horn antenna to the output of the magnetron.

Original video was pulled from Youtube updated 7/10/2016

Someone else’s crazy project

Note from wiki “a 1.1 kilowatt input will generally create about 700 watts of microwave power”

What I’d like to do

  • Build a Faraday cage so that I can safely perform testing
  • Get one of these powered up with an inline dimmer switch so that I can control the output
  • Build a horn antenna to attach to the Magnetron so that I can control the direction of output
  • Use some equipment to measure the emitted power with in controlled area
  • Use a frequency counter to get a reading of what range is play
  • Cook food from a distance
  • Light up bulbs in a field
  • Destroy some electronics

Interesting Finds

I found some interesting software on an MIT website today. There were 3 on this page that grabbed my attention.

STARCluster
StarCluster
“StarCluster is an open source cluster-computing toolkit for Amazon’s Elastic Compute Cloud (EC2)”. First off I didn’t realize Amazon’s distributed computing could be used like this. Then again I haven’t done much with parallel computing since early days with Beowulf clustering. If that doesn’t give enough of an indication this will, I used to get frustrated with some of the machines I had because they did not have math co-processors and most linux distributions at the time required them.

STARHPC
StarHPC
“StarHPC provides a virtual machine image configured for parallel programming in both OpenMP and OpenMPI technologies.” I love tinkering with custom linux distributions especially on a virtual machine. My first thought is that this would be fun to run on various embedded devices around the house.

STARHydro
StarHydro

“StarHydro is an application for distributed hydrological analysis. It allows the user to delineate watersheds and explore various watershed statistics.” Ok so this is probably my favorite find today. I love data especially when it involves the earth. I can’t wait to see someone make a complete computer model of the earth loaded up with live data fed from sensors all over the world.

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
