Justin and Jason discuss the move from Perioscope to Meerkat, Justin’s health update and why he got rid of his treadmill, how Colby blew the curve on the math final, the field trip to Caltech and the visit from the district superintendent, BVP’s anti-portfolio, how to keep from reverting to the mean, teaching kids about money and investments, the story behind CryptoIQ, Justin’s “billion dollar” secret project, Jason’s idea of how to build the Memory Hole on top of Instapaper, Kurzweil’s cyborg predictions, the MagicLeap platform, the possibility of doing another TechZing Summit, the Outernet and whether its signal could be jammed, low-power devices running off WiFi and uBeam’s ultrasound charging technology, ideas on how to interview technical candidates, the difficulty of learning advanced mathematics on your own and whether Justin’s obsession with taking shortcuts has hamstrung him in other ways.

    Hey guys, with these Perioscope and Meerkat streams, is there anyway I can view them after the stream is over?

    @Lee Not right now, but we’re looking into that…

    Hey guys, you should let everyone know at least a day before hand. I wanted to see the show, but it was so short notice

    I agree with Jorge, I’d appreciate it if you could sent a note to the email list the day before you stream!

    I’m looking forward to hearing about Justin’s secret project.

    @Jorge & @Joe – Will do! It would be fun to try to get a lot of people on the stream. It really seems to inject some energy into the show.

    Have you guys heard of http://katchkats.com. Add #Katch to your Meerkat video description tweet and the service will record and upload the live stream to YouTube.
    A nice implementation.

    @Edwin Thanks, I just set it up.

    Thank you for talking about https://cryptoiq.io on the show. If any listener wants to mess around with algo trading and needs bitcoin market data for training/backtesting please let me know. I will give free access to the data to anyone who mentions TechZing 😉

    do you have any advice in how to start out with getting up to speed in maths?

    I’d like to increase my maths knowledge but I’m not entirely sure where to start looking/

  10. Paul Cowan says:

    Or could you give a list of the math subjects that you think are important for a programmer.

  11. Jason says:

    @Paul Cowan – I think the most efficient way to get up to speed on math would be to just work your way through the Straight-Forward Math series (listed below), which contains pretty much everything from pre-algebra on up, so you can jump in wherever you feel comfortable. The books are simply fantastic and are primarily what I use for the accelerated math class I teach. They’re short and inexpensive, but are surprisingly comprehensive and contain lots of good problems (make sure you do them!). You can always refer to Khan Academy videos or sites like Math Is Fun (https://www.mathsisfun.com/) if you require additional explanation, but my guess is that you generally won’t. Assuming you remember fraction arithmetic and order of operations stuff and can start with algebra, I would estimate that with about 5 hours per week of study, you could probably complete everything up through calculus in roughly 6-9 months. Anyway, if you do decide to pursue this, please keep us posted on your progress!

    @jason first two books ordered. Our third child is due on 30th October.

    That is my deadline to get through this stuff.
