How can Launchpad be configured to keep layout after reboot?

I updated to Yosemite. I organized my launchpad but when I turned my laptop on after shutting it down, my apps weren't grouped together like I did before.

What do I need to do to keep the layout I defined?

Ridiculous number of unnecessary empty birthday calendars that can't be deleted

I have an iPhone 5 running iOS 8.1.1. My Calendar app is showing me a ridiculous number of birthday calendars ("Friends' Birthdays" under Gmail, "Birthdays" under Facebook, and 8 separate calendars named "Birthdays" under "Other"). This is what the list of calendars looks like:

I have no idea how they got there. I am syncing the Calendar app with Google, Facebook, and Meetup, but I can't imagine how that would produce such a ridiculous number.

What can I do about these? I would like to delete or merge some of them but the app is not giving me the option. Is it possible to delete most of them without losing anyone's birthday?

If I look at the Calendar app on my Mac (which is running Yosemite), I don't see all of these calendars. I only see one under Google that says "Birthdays", another under Google that says "Friends' Birthdays", and one under Other that says "Birthdays".

EDIT: I did some looking around and it seems like the "Birthdays" calendar under Gmail has my contacts' birthdays and the "Friends' Birthdays" calendar has my Facebook Friends' birthdays. But all of those "Other" birthday calendars don't seem to have a single birthday in them. I think I can delete them safely without losing anything. I just need to know how.

I logged into iCloud using the iCloud website. I clicked on the calendar icon and all I saw was two empty calendars called "Home" and "Work". I did not see all the empty birthday calendars. I didn't see anything useful or meaningful, but I wouldn't expect to because I am syncing all of my calendar events with Google, not iCloud.

Paint.NET alternative for Mac OS

I would be extremely greatful to anyone pointing me in the direction of the Mac OS analogue for Paint.NET.

Basically the way I use it is I take lots of screenshots for work, then put arrows in there, some ovals and text - it's all for documentation purposes - mainly for Confluence.

The feature I can't live without is the arrows - they have points where you can easily curve them creating a very good visual e.g. for tutorials.

And of course it's great that you can do all of that in a lightweight app, couple of clicks manner.

Thanks in advance!

Purchasing iPhone from Canada AppStore with US credit card

I am looking to purchase an iPhone for a friend who stays in Canada. I am making the payment with my US credit card. So, I went to the Canada Apple store(apple.com/ca) to do the purchase. However,when I attempted to fill in the credit card billing address, it looks like they accept only canada-based billing addresses. Unfortunately, my friend doesn't have a credit card, so I must be the one to pay for it.

How do I get around this? I really need to complete the purchase as soon as possible, so any help would be greatly appreciated.

Open HTML files on Dropbox application

On my computer I'm developing some simple front-end web pages made of typical structure:

1. HTML source code for structuring the elements;


2. CSS classes linked to the HTML;


3. JavaScript files linked to the HTML as well.

I put everything on a Dropbox folder and I'm so able to view all these files from my Dropbox application on the iPhone.

If I open the HTML files from there, I'm only able to see its basic HTML structure: no CSS is called, nor Javascript functions. Clearly because I'm not opening on a browser, but on a simple file viewer.

MY QUESTION: Is anyhow possible to open HTML files with a browser (such as Safari) from the iPhone so to be able to see the whole result (CSS, links and JavaScripts included)? I've already tried the "Open this file on..." function on Dropbox, but it doesn't show me Safari as an app that accepts that kind of file.

Thanks in advance.

Scroll lock on USB keyboard does not enable scroll lock

I have a Windows keyboard that attaches to a KVM that I use to control my Macbook Pro and my desktop. Pressing scroll lock twice on the KVM switches between the two computers. On the Macbook scroll lock is mapped to the decrease brightness button, and pause/break is mapped to increase brightness. I can switch between the two machines, but the screen changing brightness is a bit of an annoyance.

Is there a way to map the scroll lock button to using scroll lock on just the USB keyboard?
