Hope you will like it too!

Thanks everyone whom has attended my workshop session at IP3 Forum. Here’s my slides for you:

Interactive Ontario, in partnership with Bell, is pleased to present the Toronto iP³ Forum — a one-day event that will explore the changing mobile landscape and the business opportunities associated with Apple’s Touch Platform (iPhone, iPad and iPod touch), as business models adapt to a market where people are always connected.

iP³ Forum will be hosted on June 21, 2010 at Hilton Toronto, 145 Richmond Street West, Toronto, Ontario (map)

There will be two spread threads running at the same time, business and technology. I will present a tech session in the morning, the topic is “Mastering Xcode”, in which I’ll talk about the tips and tricks which I’ve discovered in the past years.

Actually, I would change the title to “Mastering Xcode 3″ as Xcode 4 is just around the corner. After play with Xcode 4 for couple of hours, I found that a lot of things have been changed. Luckily most of the tips and tricks I will present will still apply to Xcode 4.

The speakers list for iP³ Forum is pretty impressive, look forward to the event on the next Monday. Hope can see you there too!

Installation

By default it will install into /Xcode4, so you are safe to just click though almost blindly. This could change after the final release.

After install size is 5GB.

Launch

Very unstable, crashed on the first launch, the reason was because of all my existing Xcode 3 plugins.

Crashed again after removing all the plugins. Then succeed on relaunch.

Look and feel

As you’ve already see from the internet, the first reaction is this thing looks more like iTunes than Xcode 3.

Organizer

Organizer has been redesigned from ground up, it’s much easy to find the information you want.

Another very interesting thing for Organizer is Document has been merged into Organizer now, which will help me to have one less window open.

Preferences

Preferences window has been redesigned and simplified, there are only 7 icons you can click on:

Alerts, which is new. Documents, Fonts & Colors, Text Editing, Key Binding, Building and Source Trees.

Workspace

Favorites Bar is gone, replaced with much more useful Tab bar!

“Get Info” has been converted into “Utility” and put into the workspace as right sidebar.

Original “Project” Tree has been converted into tab based navigator as left sidebar.

Alerts

If you’ve already tried “GrowlCode“, this is not new for you. If not, you’ll love this feature.

iPhone Simulator

There’s one new default app in iPhone Simulator: Game Center, can’t get it working though.

All-in-all

Very well redesigned! Very buggy!

“Hacker News” from YCombinator is the major source where I get all the technology and startup news. I love reading it a lot, I’ve even created an iPad app “HackerNews for iPad” so I can enjoy it more.

Couple of days ago, the best update ever happened on Safari, so we can create Safari Extension now!

Here’s my 10 minutes work: “HackerNews OnePage” for Safari: HackerNews.safariextz

The extension only does one thing for now: provides users with the ability to browse Hacker News articles and comments without leaving the page.

How to use it after installation? Just refresh your hackernews page.

This is a port from the great work what Tim Dupree have done on his Chrome extension “Hacker News OnePage“. Thank you Tim Dupree!

Hope you enjoy it!

Short and sweet!

PCMag: Apple iPad video review from PCMag.com Reviews on Vimeo.

Peteris Krumins has done a great job on “Top Ten One-Liners from CommandLineFu Explained”. Here’s my short summary for quick reference:

#1. Run the last command as root

$ sudo !!

#2. Serve the current directory at http://localhost:8000/

$ python -m SimpleHTTPServer

#3. Save a file you edited in vim without the needed permissions

:w !sudo tee %

#4. Change to the previous working directory

$ cd -

#5. Run the previous shell command but replace string “foo” with “bar”

$ ^foo^bar^

#6. Quickly backup or copy a file

$ cp filename{,.bak}

#7. mtr – traceroute and ping combined

$ mtr google.com

#8. Find the last command that begins with “whatever,” but avoid running it

$ !whatever:p

#9. Copy your public-key to remote-machine for public-key authentication

$ ssh-copy-id remote-machine

#10. Capture video of a linux desktop

$ ffmpeg -f x11grab -s wxga -r 25 -i :0.0 -sameq /tmp/out.mpg

That’s it.
