“He [Galton] even measured the life spans of sovereigns and clergymen, which, being similar to the life spans of people in other professions, led him to conclude that prayer brought no benefit.”
— Leonard Mlodinov

Mlodinov’s “The Drunkard’s Walk…” is a fantastically good book. I couldn’t pull myself away of it, I’d read it in the morning before the work starts and right after I wrap it up for a day. A captivating overview of mathematics of chance, random, and statistics put in a very comprehendible form and language, intertwined with amusing digressions into history of mathematical thought, it connects randomness with our everyday life.  Scientific American’s comment reflect my feelings: “Delightfully entertaining”.

Recommend it wholeheartedly:

  • Very handy github-hosted automatic page refresher, will update a given URL in an iframe at a specified interval.
  • For those who seldom face a task of configuring SSL, here’s an SSL config generator for various web servers. The point is this generator gives you a config that matches current demands in terms of security, i.e. vulnerable cyphers would be disabled, etc.
  • If you accidentally downloaded a huge file from an svn repo that you don’t want to keep in your working copy, you can remove and ignore them in the following

    You can later re-enable the folder with svn update --set-depth infinity bigFolder
  • This has been sitting in my notes for a long time: why DNS root record cannot have CNAME and how to live with it: CloudFlare’s DNS flattening. Frankly, they should just add this bit into DNS specification.
  • Bleep peer-to-peer instant messenger got released. It’s frustrating to see the industry failing at producing a modern advanced and convenient IM really. If Bleep is going to maintain (semi-)direct connections with your contact list, sending updates and notifications, that would dry your battery on mobile devices.
  • Reminder for myself: iOS firmware downloads.
  • And finally, meetup.com is a very odd platform. I’ve joined it few months earlier cause we organised a group and now for some reason, meetup.com decided I’m some sort of a fraudster or spammer and limited my account so I virtually cannot do anything, neither send a message, nor edit my profile. After googling I found I’m not the only one suffering: Meetup automatic fraud systems out of control. Support doesn’t seem to be cooperative at all with the only one suggestion: remove your existing account and register a new one. Well, thanks Meetup, I’ll remove my account; not sure I’ll be registering again though.

This has been a busy month and, what pleases me, very productive. Apple’s recent announcement managed to surprise in many ways, which is delightful as well; if you’re still on Mountain Lion consider upgrading, Mavericks got it right in so many places, that it’s even difficult to tell which changes are most compelling.

I’ve lagged on links, however, so catching up:


  • What nohup does:

  • Query against over 1500 global DNS servers



  • I’ve finally found where the phrase “With sufficient thrust, pigs fly just fine” comes from! Appears it’s from RFC1925:

(3) With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they
are going to land, and it could be dangerous sitting under them
as they fly overhead.

But references to flying pigs appear even in Lewis Carrol’s Alice:

"Thinking again?" the Duchess asked, with another dig of her sharp little chin.
"I've a right to think," said Alice sharply, for she was beginning to feel a little worried.
"Just about as much right," said the Duchess, "as pigs have to fly...." — Alice's Adventures in Wonderland, Chapter 9.
