Iteration & Generators: The Python Way

Speaker: Luciano Ramalho

Lazy Iterable: It’s iterable but only produces results when iterated on.

“__” = dunder.

protocal (synonmous with Java interface) e.g. collections.Sequence, your class can subclass this instead of object.

Title: How the Internet Works

Speaker: Jessica McKellar

Use scapy traceroute to see how your packets got to you. Then use geopy to geolocate them.

Software

• scapy
• geopy
• twisted – for server
• wireshark – capture and listen to network traffic. Can monitor your LAN with this tool.

Make More Responsive Web Apps with SocketIO and Gevent

Speaker: Luke Sneeringer

Can’t get socket.io directly from their site. Need to get from examples.

var socket = io.connect('http://example.com/namesapce')

Uses ‘emit’ and ‘on’ for events.

We did not have the lemon grass or kaffir lime leaves so we steeped some dried lemongrass in about a 1/4 cup of water and added a few teaspoons of lime juice. We also used chicken instead of shrimp. We are add about 3 tablespoons of brown sugar. Also we ended up using the full can of coconut milk.

It turned out pretty good. IT is still missing something, maybe next time I try with the lemongrass and kaffir lime leaves.

I want to use open-source design software on this thing, preferably Python based. I have been reading http://www.3dprinting-forums.com/ to learn more about 3D printing. This page has some useful links to design software for 3D printing.

Here are the short list of printers and software I have found so far.

Printers

Cubify ($1299)

http://cubify.com/PJP, Tough Recyclable Plastic printing material, 250 microns resolution, runs on windows and OS-X 10.8. Uses proprietory .CUBE files and software. Has a build space that is 14 x 14 x 14 cm or 5.5 x 5.5 x 5.5 inches.

Fab@home

http://fabathome.org/They have a kit and can suggest vendors that will sell completed ones. This looks more lie an open source project to develop a printer/design system. It might not be the best place to look to purchase a hobby printer.

Solidoodle 3rd Generation ($799)

http://store.solidoodle.com/index.php?route=product/product&path=59&product_id=79.These are on back order for 8-10 weeks. Has a build size of 8 x 8 x 8 inches. Has open source design software that is Windows, Mac, Linux compatible abd uses STL format.  Fused Filament Fabrication (FFF) a.k.a Thermoplastic Extrusion. Resolution .3mm normally, hi-res .1mm.

Makerbot Replicator 2 ($2199)

http://store.makerbot.com/replicator2.html100 micron resolution, 410 cubic inch build volume

I made some slight modifications.
1) I marinaded the meat using the entire sauce recipe for about 6 hours.
2) Added a few squirts of Sriracha to give it some kick.

We stir fried some red cabbage, broccoli, and celery with the left over marinade and served it all over Jasmine rice.
The meat2 turned out pretty good but not great. First, I think it has too much cumin. I’d take it down to 1/2 tablespoon. And secondly I would add some lime juice to give a little citrus acidity.

• 2 tablespoons vegetable oil
• 2 cloves finely minced garlic
• about 1 small onion, minced (1/2 cup)
• 1/3 cup ketchup
• 1/4 cup Sriracha hot sauce or any chili hot sauce (or more for a spicier sauce)
• 1 tablespoon vinegar
• 1 teaspoon fish sauce or soy sauce
• 1/4 teaspoon ground cumin
• 1/4 teaspoon ground cayenne

The great thing about smoking the turkey is that it will be done even if we lose power. Last year we had a big storm and lost power for a few days just before Thanksgiving and this year we just got the back back on Tuesday afternoon.

This year I will be smoking a 12.5lbs Fircrest Farms Free Range turkey that cost $23. I brined it in a 5 gallon bucket for about 36 hours. This year’s brine recipe came straight from a Kikkomans soy sauce label, slightly modified based on what we had in the spice rack. Here it is

• 2 gallons of water
• 1.5 cups soy sauce
• 1 1/2 cups kosher salt (I used sea salt because I had no kosher salt)
• 1/2 cup sugar
• 2 tbsp dried sage (I only had about 1 tbsp)
• 2 tbsp dried celery seed (I used a cap full of celery salt)
• 1 tbsp dried thyme

2012 Thanksgiving Turkey Brine

I put the bird in a 5 gallon Home Depot bucket and put in on the back deck with a tin foil lid for the night. I will probably throw it in the garage in the morning because that will be cooler than the deck during the day.

sudo indexer --all

This did not work. I kept getting an authentication error.

The solution was to edit the postgreSQL pg_hba.conf file to use the ‘md5′ authentication method, previously it was set to ‘trust’. This file is located at /etc/postgresql/8.4/main/.

# Database administrative login by UNIX sockets
local   all         postgres                          trust
 
# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD
 
# "local" is for Unix domain socket connections only
local   all         all                               md5
# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
# IPv6 local connections:
host    all         all         ::1/128               md5
host    all         all     96.41.170.7/7         trust

Don’t forget to reload the postgreSQL server

 sudo /etc/init.d/postgresql-8.4 reload

.

After configuring postgreSQL to use md5 passwords, I need to giv my postgeSQL user a password (by default the user’s password is set to null). To do this I logged in with the ‘postgres’ user and changed my accounts password.

psql -U postgres

ALTER USER username WITH PASSWORD 'password';

I then try to view the devices connected and get an empty list. Also ddms wil lstart but it’s not connected to anything.

My problem was that I didn’t enter my computer’s IP address properly in the Applications -> Development -> Debugger IP address section. After I put the correct IP address in, it worked.
