   QuickCheck is awesome and indispensable in the Haskell world. Instead of writing a single unit test with a hard coded example case, QuickCheck allows you to describe that unit test generically and it can randomly generate unit tests of the

   I've been wondering this for quite some time. Thanks for the clearly explained response. Is this documented somewhere or just something you've observed?

   Agreed. We're always trying to move Template Haskell code into new and more powerful type system features.

   Any reason this doesn't just integrate with Grafana?

   There have been numerous attempts at making a better Haskell prelude. Basically basic functions like getting the head of a list can have a runtime error (for example, the list is empty). That's unnecessary in Haskell (could return a `M

   Thanks for releasing this. Any plans to package via brew or apt?

    Turns out Microsoft is still accepting Bitcoin. The post was a mistake. http://www.cnbc.com/2016/03/14/microsoft-stops-accepting-bit...

    Microsoft did liquidate to USD right away using a company called BitPay. BitPay would take on the short term price risk and Microsoft would get exactly what they quoted in USD. Microsoft was not subject to BTCUSD price fluctuation in this s

    My guess is that they gave it a try and the purchase volumes never materially compared to credit card payments. Integration was done very poorly. You had to go to a special link "commerce.microsoft.com" and click on a small, un-st

    Good point. The Ansible community who happened to be talking to me on IRC about this basically said that at least at this point, you have to look at all your role code no matter what anyway. Meaning scope wasn't the core issue. But lac

    Some things I really like about Ansible are: - Super simple declarative yaml configs - Agentless. You needed to have SSH working anyway so Ansible just uses that. With ssh pipelining it's so fast. - The community support is huge and ex

    Agreed. In fact variables are scoped by "play" not by "role" which is almost weirder. For those who don't know the organizational structure from largest to smallest is playbook->plays->roles->modules/t

    I've wondered that myself. I think the reason might be monads are used to represent IO computations and state mutation so people are interested in jumping straight into that. Honestly I use functor as much/more than I use monad in

    Something that doesn't help the Math->CS understanding of Functors is, for example, that languages like C++ use "Functor" to mean other things (function pointer in this case).

    Doug Beardsley (mightybyte) is a very prominent Haskeller. A maintainer of the Snap Web Framework for Haskell and Co-organizer of the NYC Haskell group. Definitely worth reading his stuff. Great tutorial as well!

    Does anyone have a success story for this type of backup and retrieval on another service?
22. 52.▲
    by LukeHoersten 11y ago

    Yeah that's exactly what I think. Software forking (and even blockchain forking) allow us to "vote with our feet" so we don't need to mandate central control.

    Do you have connection pipelining enabled?: [ssh_connection] pipelining = True Ansible 2 is extremely fast for me.

    Same here. Ansible has been added to my short list of life changing programs in my tool belt along with Mercurial and Emacs. These types of applications come along every 10+ years or so for me.

    I was an avid Xmonad user on my Linux desktop but never was able to get it working quite right on OS X. I would love if that would change. Unfortunately I don't see anything new on the link posted here.
