YABI meets MobileMe Calendar Beta

Apple have recently released the beta version of new MobileMe Calendar: it’s cool, of course, but all calendars on your Mac won’t be local anymore, as they are replaced by CalDav ones.
Unfortunately the Calendar Framework provided by Cocoa doesn’t fully support CalDav: then YABI tries to recreate the calendar, a new local calendar is created instead of a CalDav one.

I’ve already wrote the solution to this bug and soon I’ll release the new version which also includes a way to exclude person from sync.

YABI 1.0.4 released!

“This changes everything. Again.”

YABI core functions have been totally reimplemented and, above all, completed.
This version addresses few bugs, which caused YABI Agent crashes (e.g. when an event name is changed in AddressBook).

I’ve also been asked for new interesting features, I’ll work on them in spare time:

use remote calendar as target
excluding birthdays
enhanced nickname support

Upgrade note
We suggest to deactivate YABI before upgrading; follow these few steps:

Open YABI preference pane
Click on Deactivate button and quit System Preferences
Upgrade YABI by double-clicking on the new icon

Download YABI at http://www.devzero.it/yabi/ and check it out!

Selectable boxes

If you had ever used iSync, probably you’ve been asked to resolve a sync conflict at least one time: the panel shown to the user contains two boxes , mutually excluded i.e. you can only choose one of them.

DZSelectableBox is a subclass of NSBox view which emulates this behavior. An instance of this class comes with one more variable member, the box state: when the box is marked as selected, an inner rounded path is drawn inside its bounds; DZSelectableBox honors title position, if it’s visible. You can use this class in two different manners: standalone or as part of a radio group.

Give me a… second chance!

As university assignment, I wrote a small virtual memory simulator which implements pagination; the algorithm chosen to replace a target page is the enhanced second chance, also known as “clock algorithm”: this solution comes out as natural evolution of FIFO algorithm, working out the problem of removing those pages which are frequently accessed.

In computing, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and logical operations. The ALU is a fundamental building block of the central processing unit (CPU) of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers.
