Radio Liferay Episode 60: Performance and Permissions with Preston Crary

  An episode on the "Per" things: Performance and Permissions. I spoke to Preston Crary, who amazingly was not mad at me for losing an earlier recording.

We're talking about these (and more) topics

  • We open with the attention to detail that's required for working on performance tuning and some short conversation about this topic.
  • Sadly, there's not often a single silver bullet, but many areas of dust.
  • Sometimes the fastest code is not the most optimal
  • Continuing with Preston's work on Permissions:
  • ResourceBlock is deprecated, and there's an easy migration path
  • The usecase for Resources, ResourcePermission, and ResourceBlocks (as they're not at all visible on the UI)
  • Preston's way through Liferay from Support to working on the topics that he's now working on
  • The new API for Permissions - and the documentation is also done already (as of me writing this article, not yet published, but available on github - should be a matter of days or hours)
  • Should you implement your own permission system? (and how the answer to this question might change in 7.1)
  • Upgrades are being performance tuned. I smell a future episode coming up. Paging the team that is working on this area
  • The remarkable memory savings that refactoring the UserBag introduced
  • What happend during login
  • Passwords are PBKDF2WithHmacSHA1/160/128000 hashed, a deliberately expensive password hashing algorithm.
  • LPS-75747 and an update to my hardball question: Document Library's default.xml is still in core, can't be updated through a module, just through an ext.

Radio Liferay Episode 46: Thomas Schweiger on Coffee

  The nerdiest topic so far: I'm speaking to Thomas Schweiger, german national barista champion 2010-2012. He was sponsored by our german partner Prodyna to prepare coffee during this years Devcon and Portal Solutions Forum Germany.

We talked about

  • What do you need to do to become Barista Champion?
  • Can you describe upfront what your coffee will taste like when you prepare it?
  • Importing coffee, roasting, drying, grinding and preparing
  • Latte Art (learn it by just listening to this episode):
    • Foam the milk to be a homogenous liquid - stop adding air at 30°C, then roll around the foam to get microbubbles. The really hard stuff is to determine when to drop the milk under the coffee's crema and start drawing images with the foam on top.
    • Find Latte Art tutorials on Youtube (or find out what it actually is and what pictures people actually do)
  • Shoutout to Wolfram Sorg, from Prodyna Sales, who is teaming up with Thomas
  • Did you know you can be a coffee consultant? Thomas is. He's consulting on coffee farms, cafés and barista training.

Everyone who has missed to taste his fabolous coffee, to spend time for a small talk has definitely missed an outstanding moment!

Cheers
