Posted by jpluimers on 2017/11/29

[WayBack] Objective-See: tracking down the cause a serious authentication flaw in Mac OS X / MacOS / Mac OS 10: resetting the root password by just clicking OK.

Via: [WayBack] How the MacOS High Sierra ##IAmRoot bug actually works. ##insightful … TL;DR the return value of the verify password function is interpreted wrong. Fix looks trivial. But this IS a serious bug. – Jan Wildeboer – Google+

Note the bug was already revealed two weeks ago: [WayBack] … after updating to High Sierra, the two admin accounts on this machine are all of a sudden standard accounts …

Via: [Archive.is] Mike Myers‏ @fristle: Perhaps nobody noticed two weeks ago when the root login vulnerability in macOS High Sierra was shared as a helpful tip on Apple’s own Developer forums. https://forums.developer.apple.com/thread/79235

QA frustrations: waiting  almost a year for a resolution

Posted by jpluimers on 2017/11/29

A frustrating part of reporting issues to many companies is the time it takes to get a response at all or a response “maybe in the far future”.

Below is just an example, but I see this regularly, for instance another example (scheduled in a later security related post) a company that responds to a “welcome in the 21st century” complaint on enforcing a 16 character password limit by responding “maybe we are going to extend it in the 22nd century”.

[WayBack] why are the parameters in a reverse order.

Canonical Delphi Singleton Pattern – Stack Overflow

Posted by jpluimers on 2017/11/29

Though I try to refrain from using the singleton pattern when possible (I prefer dependency injection over accessing “globals” that usually tend up to be not so global after all), sometimes I need to.

In C# there has been a canonical singleton pattern implementation by John Skeet for a very long time at [WayBack] C# in Depth: Implementing the Singleton Pattern.

I just found out there has been similar implementations in Delphi both in this question (which like many useful questions is marked “closed”, oh the joy of StackOverflow): [WayBack] “Delphi Singleton Pattern – Stack Overflow:

I like both implmentation, but usually take the first as mostly locking has little overhead and sometimes two instances cannot co-exist (though that’s lessened when part of the singleton uses lazy initialisation, for instance from Spring4D).

tiOPF discussion thread

Posted by jpluimers on 2017/11/29

Sometimes the title of a G+ entry looks not so interesting, but then you read the comments. In this cast it’s about the mediator pattern support in the tiOPF object persistence framework, how it works very well from Free Pascal and both classic and  modern Delphi compilers and why developers dislike ARC. It’s cool as it allows you to decouple UI from business logic and separate out business logic from your application into a back-end.
