  • Apple planning to ditch Intel chips in Macs for its own custom silicon in 2020

    My Python 3.6 plotting script execution time:

    2015 rMBP15 w/Intel Core i7-4980HQ (2.8/4.0 GHz): 91.1 sec

    2017 iPad Pro 10.5 w/Apple A10X (2.3 GHz): 91.5 sec

    This is 45 W vs a 10 W envelope or so. Use Pythonista on iPad. Terminal on macOS. Don’t know if the Core i7-4980HQ actually turbo-ed to 4 GHz. Who knows. That’s why you do a lot of testing.
    Typically python is single threaded. With cython you can use the OpenMP backend for multithreading anywhere Python api calls can be optimized out. Now Apple's version of Clang doesn't support OpenMP, so you are running on one core. Turbo varies. If you're using AVX extensions, it typically runs at native clock speeds. 

    Of course it's possible to be bound by something other than cpu. You can be bound by memory/cache bandwidth and other things. The test overall tells you a grand total of nothing without proper context.
  • Tim Cook sells 40k Apple shares worth nearly $5M

    This is a casual legal question and not an accusation:  How DOES an executive avoid charges of insider trading in a situation like this?  How big does a trade have to be before questions are raised?  Presumably buying shares TODAY is fine because (in theory) we're all on the same page with yesterday's disclosures, but YESTERDAY Tim knew more about Apple than any other investor and he was trading.  Again, I don't think Tim did anything wrong (and the dollar amounts are, for him, relatively trivial), but it seems like a very, very grey area.
    It's in the first line of the article. He set these trades up some time ago.
  • Apple and Foxconn weighing $7 billion display plant in U.S., report says

    Unfortunately the US has screwed itself because of it's education system. You go to a Ph.D program and pretty much 80-90% of the PhD candidates are foreign born. Americans are getting degrees in psychology and sociology instead of STEM creating a huge opportunity for foreign workers especially foreign Software Engineers. 
    A phd prepares you to work in academia or a research lab. Given the poor job market and outlook in these areas, fewer US students apply. Foreigners often use graduate school in the US as a means of immigration, although it has some obvious limitations. You shouldn't need a Phd to work as a software engineer.

  • Apple to offer 32GB of desktop RAM in top-end 2017 MacBook Pro, 16GB for 12" MacBook

    Different people have different needs!   Nothing really surprising there.    My problem with the mac Book is the small screen that is an issue only older people can really relate too.    Even my 13" MBP challenges me at times.
    I don't think I could ever use a 13" screen. I don't know how you do it. 
  • Apple to add some 2009 & 2011 Macs to vintage and obsolete list on Dec. 31

    Soon the current top of the line 2013 MacPro will be considered Vintage and its still for sale (as if it were new pricing). A wise man named Phil Schiller once said that its "really sad" that more than 600 million PCs still being used are more than 5 years old. I am really interested to know if he thinks its "sad" that Apple is selling their NEW MacPro's that soon will be heading into its fourth year without an update? or is it the people that buy them today will be considered "sad" in one years time because they own new 5 year old tech?
    That's incorrect. The vintage list doesn't always match the availability of software updates. Once something is marked vintage, it's not guaranteed to be repairable. Repairs are contingent on availability of parts. The 5 year timer typically starts when a model is replaced, not when it is released. The early 2011s macbook pros were replaced in October 2011, so they hit the list this year. The late 2011s will be in the next batch, as they were replaced in 2012.
