- From the folks at Amazon
- AWS Activate
- A program to provide resources to startups: from free tier usage, labs, webinars, support and AWS credit
- Self-Starter Package: for any startups
- Portfolio Package: for startups in select accelerators or seed funds. Will be ‘audited’ by Amazon and will be given much better benefits vs Self-Start Package
Cloud Computing in Africa
- From Thomas Shaw, the tech man behind
- Providing unique perspectives with regards to security, reliability, scalability of AWS especially compared to local hosting.

28th July 2014 – Introduction to Chef held at Sacon Group for the Chef Meetup group
Chef and Chef DK: The Chef Development Kit
- by Michael Ducy (@mfdii), a Global Partner Evangelist at Chef
- PDF slides
- Chef essentially enables the “infrastructure as code” devops movement
- Versionable, testable, and repeatable as application code
- Relies on reusable definitions known as recipes to automate infrastructure tasks
- Recipes use building blocks called resources (e.g. file / template / package)
- Recipes are stored in cookbooks
- A cookbook is the fundamental unit of configuration and policy distribution
- Chef server stores your recipes as well as other configuration data
- Chef client is installed on each node in your network
- Chef client periodically polls the Chef server for new configurations and applies if necessary
- Chef DK
- A component of Chef to enable organizations to develop internal best practices for Cookbook development and testing
- A curated set of open source tools for Cookbook development
- Download at http://downloads.getchef.com/chef-dk
- chef – a new command to make development easier
- Berkshelf – automatically resolve cookbook dependencies
- Test Kitchen – framework for integration testing
- ChefSpec – unit testing of Chef cookbooks
- Food Critic – linting tool for Chef cookbooks
- Standard Chef tools – knife, chef-zero, ohai, chef-client

24th July 2014 MelbDjango Hackfest held at Common Code and hosted by Curtis Maloney for the MelbDjango Meetup group.
Mostly being newbies and with some people interested in testing, Curtis started off showcasing his new Django Classy Settings before covering some topics on testing and other miscellany
TAkeaways / Links from the night
USB battery packs / powerbanks (or whatever you call them) are great when you’re out and about and need to charge your devices but there are some features which you should look out for when buying one
- Buy from a reputable source
- Sufficient capacity
- You need a powerbank that is capable of charging all your devices and has enough juice to get you through the day
- Phones: ~2000mAH, 7″ tablets: ~4000mAh, 10″ tablets: ~8000mAh
(iPhone 5S: 1560mAh / HTC One M8: 2600mAh / Lumia 1520: 3400mAh / S5: 2800mAh / iPad Air 2013: 8820mAh / Nexus 7 2013: 3950mAh)
- Output Charge speed
- Ensure it can charge your device at the best and fastest speed
- Tablets usually 2A
- Phones usually 1A
- Passthrough ability
- When the powerbank is being charged when connected to a power outlet, passthrough allows it to charge any device connected to powerbank, straight from the power source and not from the powerbank itself: perfect if you want to leave all your other charges behind and charges all your devices with just a single power outlet! (Note: may want to ensure that it charges at full USB charge speed)
- Battery gauge
- Nice quick way to know how much capacity is left in your powerbank
- Allows rationing of your charge
- Charges via a standard USB cable
- Being able to charge your powerbank using a standard cable is ideal as proprietary charges can be hard to replace if lost
- Ideally the same cable as your other devices (my powerbank can charge via miniUSB but all my devices use microUSB so it is one extra cable to bring along)
- Multiple USB ports
- for those with multiple devices (or for sharing with others)
- Port positions
- Some USB cables may be bulkier than others and thus powers that are spaced out are useful so that you can utilise all ports at the same time
- Ideally all ports on a single side so it can be pocketable or just easily placed on a surface standing up if needed
- Charges quickly via USB
- If allows charging via several methods (e.g. proprietary cable as well as via USB), ensure that it can charge quickly over USB (my Sanyo powerbank charges very slowly over USB)
- If it supports passthrough, added bonus ability to maintain proper charge, amperage and voltage when plugged/unplugged from power source
- This use case comes from using your powerbank as the power source for devices like the Raspberry Pi: you want it to provide the power to the Raspberry Pi and if the power source gets disrupted and you do not wish for the device to get restarted, the powerbank must maintain a proper current/voltage so not to trigger a restart.
Note: a 4000mAh powerbank will not charge a 2000mAh phone battery twice due to inefficiencies, battery health and other factors.

Notes/Improvements for next year
- Power extensions & power strips for the workshops
- Ideally free Internet (unless Troy comes)
Turning on a device should be easy and simple and shouldn’t take a lot of effort. Physical buttons are the best: giving you tactile and instant feedback.
Which would you rather?
Devices with physical home buttons (e.g. iPhone / Samsung S series) are the ideal IMO while Nexus devices (e.g. Nexus 4 pictured above) force you to use ‘the claw’.
How does one pocket this?
- both USB/charging port and headphone ports should be on the bottom
- ensures pocketability when charging on the go with a USB battery pack while listening to music
- Nexus 5
- Samsung Galaxy S5
- Lumia 930
If you’re stuck on with a device with non optimal port placement, I suggest getting right angle connectors for your headphones as it at least allows the device to rest on the connector without straining anything too much (you could also get a right angled USB connector, but it is yet another thing to worry about if you care about USB charging speeds)
