Raspberry Pi Zero: the $5 computer

Of all the things we do at Raspberry Pi, driving down the cost of computer hardware remains one of the most important. Even in the developed world, a programmable computer is a luxury item for a lot of people, and every extra dollar that we ask someone to spend decreases the chance that they’ll choose to get involved.

The original Raspberry Pi Model B and its successors put a programmable computer within reach of anyone with $20-35 to spend. Since 2012, millions of people have used a Raspberry Pi to get their first experience of programming, but we still meet people for whom cost remains a barrier to entry. At the start of this year, we began work on an even cheaper Raspberry Pi to help these people take the plunge.

Below is the configuration for this new Raspberry

  • A Broadcom BCM2835 application processor
    • 1GHz ARM11 core (40% faster than Raspberry Pi 1)
  • 512MB of LPDDR2 SDRAM
  • A micro-SD card slot
  • A mini-HDMI socket for 1080p60 video output
  • Micro-USB sockets for data and power
  • An unpopulated 40-pin GPIO header
    • Identical pinout to Model A+/B+/2B
  • An unpopulated composite video header
  • Our smallest ever form factor, at 65mm x 30mm x 5mm

  • Raspberry Pi Zero runs Raspbian and all your favourite applications, including Scratch, Minecraft and Sonic Pi.

    Testing tools for Angular JS

    Karma is a great test runner made for Angular, but can also be used with any other Javascript framework. It supports any type of testing: unit testing, midway testing and E2E testing.

    Books on Java performance tuning

    We usually do a performance research by writing small stop watch and it will log time taken for each business methods. You create stop watch methods something like startWath and stopWatch to start and stop a timer. The performance tuning on web applications vary from server to server since there are some server level tuning also improves your application's performance.

    Below are some books which might help you.

    Java Performance: The Definitive Guide is a really good book and its quite latest as well - covers G1 GC in depth.

    Then there is another book: Java Performance by Charlie Hunt and Binu John even this book is good expecially the java performance troubleshooting guidelines are good.
