A lesson from a photographer

2012-01-25T08:32:00.004+02:00

"While working on my latest painting this month, the Cougar Totem in the video above, I woke up at 4:00am on a Sunday, because I knew that I only had a few hours left before the painting was done, and I was excited to finish it. When you find that which you would do even if nobody paid you, that creative work that feels indescribably right, then that is the work you’re supposed to be doing.

If you haven’t found it yet, keep moving forward. Challenge your own assumptions, be willing to experiment and get comfortable with rejection. I’ve always learned much more from my failures than my successes. Most importantly, keep trying new things, because the next one could be it. And even if you are lucky enough to find the work you’re meant to do now, it’s still only a stepping stone to the work you’re meant to do later."

A players hire A+ players

2011-11-03T23:47:00.003+02:00

"Actually, Steve believed that A players hire A players—that is people who are as good as they are.
I refined this slightly—my theory is that A players hire people even better than themselves.
It’s clear, though, that B players hire C players so they can feel superior to them, and C players hire D players. If you start hiring B players, expect what Steve called “the bozo explosion” to happen in your organization."

Create a Gmail POP3 account

2011-09-03T21:25:00.002+03:00

When creating a Gmail account using the Mail application that comes with Mac OS X 10.7 (a.k.a. Lion), it only allows you to create an IMAP account.

If you do not want that, hold the option button down until ‘Create’ turns into ‘Continue’ and you are done!

Running Lion

2011-09-02T10:25:00.004+03:00

Earlier today, my iMac started running Lion.
It was pretty tricky to do the clean install I wanted. I had to install Snow Leopard without any apps, update to Mac OS X 10.6.8 and then upgrade to Lion.

Everything looks fine until now. I am now installing MacPorts software. The two things left are SuperDuper! and LaTeX. I also have to find which version of MySQL I will install as Lion does not come with MySQL.

Installing Lion 10.7.1

Lion FAQ

2011-08-16T21:15:00.005+03:00

Have I already installed Lion?

No.

Why?

Because I have some work to do.

What kind of work?

I have to write articles (using MS Word) about WireShark, LaTeX and Octave and I do not want to have compatibility issues.

Will I install it?

Yes, possibly at the end of August or at the beginning of September 2011.

Anything else?

I do not find something in Lion that I desperately need, Snow Leopard is just fine for what I do (iOS programming, photography and writing articles). Nevertheless, I want to have the latest version of Mac OS X for programming reasons. I would also like to install the 10.7.2 version of Lion but I do not know when it will be available. This time I will do a clean install - install everything from scratch as I want a clean system.

I usually like to install combo updates on my iMac.
After downloading 10.6.8 combo the screen of my iMac went black and I had to turn it off (using the power button).

After that, although it looked like everything was fine, I successfully re-installed 10.6.8.

10.6.8 is available

2011-06-24T07:33:00.001+03:00

iPhone is case-sensitive

2011-05-30T18:42:00.018+03:00

I had a strange issue today while programming my iPhone. Although the application was running find on iOS Simulator, it crashed on my iPhone 4.

The iPhone was generating the following error:
2:53 unknown Pickers[15251] : *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:]: nil string parameter'

The problem was a wrongly typed file name. The "wrong" command was:
NSString *path = [[NSBundle mainBundle] pathForResource:@"Crunch" ofType:@"wav"];

and I had to change it to (notice the small __c__)
NSString *path = [[NSBundle mainBundle] pathForResource:@"crunch" ofType:@"wav"];

The funny thing was that both of them were working on the iOS Simulator but only the second one on my iPhone! So, iPhone is case-sensitive.

Tab bar items

2011-05-28T18:24:00.000+03:00

As I was reading a book on iPhone 3 development, I thought that it would be useful to point out the new way (in Xcode 4) of creating tab bar items.

In Xcode 3, this job was done from the Attributes inspector of the Tab Bar Controller.
You should now drag a Tab Bar Item from the library to a Tab Bar Controller.
