Quicksilver + ServiceAPI: the authentication issues

It’s possible to run Quicksilver and ServiceAPI on a same site, with some modifications, as I blogged here. However, if you go down that path, there is something you must keep in mind: They are not using the same authentication mechanism.

I’ve seen issues where Quicksilver implementations have some WebAPI controllers, which were working fine until ServiceAPI is installed. The controllers started returning null for CustomerContext.Current.CustomerContact, and so on, breaking some functionalities. It’s bad, yes, but it happens because of reasons.

How can Horizon: Zero Dawn be (even) better?

If you own a PS4, you might want to try out Horizon: Zero Dawn, and if don’t have a PS4, you might want to buy a PS4 Pro + a HDR TV to try it out. Yes, the game is a blast to play: vast, beautiful world – which will drop your jaw frequently, and fun, exciting combat with the dino-robots. The game is selling very well and an expansion is under the work already – and I’d not be surprised if a sequel Horizon: Zero Dawn is announced in the future. But, can it be better? Yes! How?

The super short review of Horizon: Zero Dawn

Plus:

  • The game is very well polished. Everything seems smooth, and I’m yet to see any game breaking bugs (I’m looking at you, Witcher 3, and XCOM 2)
  • A vast, beautiful open world. Probably the most beautiful ever in a game.¬†Even on the original PS4, it looks spectacular. PS4 Pro + HDR will blow your mind away – well, Sony made¬†sure the game is a showcase for PS4 Pro, so that’s expectedIf you think Rise of Tomb Raider was visually stunning, think again. HZD easily blows it out of water. In short, it will drop your jaw!
  • The combats versus machines are engaging and rewarding. The bigger, badder the robot, the more satisfying you’ll be after a battle. You will have to be both smart, and fast to win. The variety and diverAlso, the Critical Hit move feels both powerful and satisfying.

Neutral:

  • The story is fine, but not really ground breaking. Passable but don’t expect anything like The Witcher 3.
  • The open world settings get bored after a while. Still many things to do, but you’ll probably want more.

Minus:

  • The combats versus humans are … meh. It’s not that bad, but compared to the machines, humans are just boring enemies which bring very little enjoyment to the table.
  • The voice acting is underwhelming. In many cases, voice actors do not sound convincing as they should. The NPC faces are also quite generic and you’ll have hard time remember who is who.
  • Stealth action is a joke – you caused an explosion and your enemies are still acting like nothing happen. If you expect the level of Metal Gear Solid V depth – I have bad news for you.

Verdict:

9/10. Buy it! If you have PS4 Pro + HDR TV and it’s easily a must have. If you don’t, then this is a very valid reason to buy those!

Tale from inside TransactionScope

One of the last things you want to get from your Commerce site is that the order data is gone. What can be more confused than if your log shows that the cart has been converted into a purchase order, you even got the PO number, but after that, the order disappears? It’s nowhere to be found, even if you look into database. It’s kind of magic, but not the kind of magic you would want to have.

But everything happens for a reason. And actually it’s with a good reason: data consistency.

Episerver Commerce has the concept of TransactionScope. Simply put, it allows two or more database operations to be done as atomic: Either all of them succeed, or all of them will revert back. If a TransactionScope contains 3 operations A, B, C, then even if A, B succeeded, but C is yet to commit, and something goes wrong, then A and B would be reverted.
